PREFACE
This Handbook contains information and service procedures to assist the
service technician in correcting conditions that are not always obvious. Ser-
vice procedures considered obvious are intentionally omitted.
Using the information in this Handbook in conjunction with mini-manual,
which is included with the appliance (self clean models only) will provide
comprehensive information on your model.
Non-self clean gas range products do not have mini-manuals, but equivalent
information on gas adjustments, electrical wiring schematics, diagnosis,
and service procedures as included in this Handbook.
Range wiring and schematic diagram is supplied with user information for
all gas ranges.

IMPORTANT SAFETY NOTICE
Major appliances are complex electromechanical devices. General Electric
Company's Major Appliance Service Publications are intended for use by
individuals possessing adequate backgrounds of electrical, electronic and
mechanical experience. Any attempt to repair a major appliance may result
in personal injury and property damage. General Electric Company cannot
be responsible for the interpretation of its service publications, nor can 1t
assume any liability in connection with their use.
SAFE SERVICING PRACTICES
To preclude the possibility of resultant personal injury *and/or property
damage, **it is important that safe servicing practices be observed. The
following are examples, but without limitation, of such safe practices.
1. Before servicing, always disconnect the product from its electrical power
source by removing the product'’s electrical plug from the wall receptacle,
or by removing the fuse (or tripping the circuit breaker to OFF) in the
branch circuit serving the product.
NOTE: If a specific diagnostic check requires electrical power be applied
(e.g., a voltage or amperage measurement, etc), reconnect electrical power
only for the time required for such a check, and disconnect it immediately
thereafter. During any such check, ensure no other conductive parts (pans,
etc) — or yourself — come in contact with exposed current-carrying metal
parts.
2. Never interfere with or bypass the proper operation of any feature, part or
device engineered into the product.
3. If a replacement part is required, use the specified General Electric Company
part, or an equivalent which will provide comparable performance.
4. Prior to reconnecting the electrical power source to the appliance, be sure
that:
a) all electrical connections within the product are correctly and securely
connected,
b) all electrical harness leads are properly dressed and secured away from
sharp edges, high-temperature components (e.g. resistors, heaters, etc.)
and moving parts,
¢) any uninsulated current-carrying metal parts are secure and adequately
spaced from all non-current-carrying metal parts,
d) all electrical grounds — both internal and external to the product — are
correctly and securely connected,
Page 2
mip mgm,
e) all gas connections are properly tightened.
f) all panels and covers are properly and securely reassembled.
5. Read the SAFETY PRACTICES section in this Book for additional SAFE
SERVICING PRACTICES.
3. Don't attempt a product repair if you have any doubts as to your ability to
complete it in a safe and satisfactory manner.
PERSONAL INJURY, in the form of electrical shock, burns, cuts or abrasions,
etc., can occur spontaneously to the individual while attempting to repair
or service the product; or may occur at a later time to any individual in the
household who may come in contact with the product — unless safe servicing
practices are observed.
**PROPERTY DAMAGE, resulting from fire, smoke, etc, can occur immediately
or at a later time as a result of attempting to repair or service the product —
unless safe servicing practices are observed.

CONTINUOUS CLEAN OVEN CARE
The inside of the oven — usually the
top, back and sides — are finished with
a special coating which cannot be
cleaned in the usual manner with
soap, detergents, steel wool pads,
commercial oven cleaners, coarse
abrasive pads or coarse brushes. Their
use and/or the use of oven sprays will
cause permanent damage.
Note: On some models, the inside of
the door may also have the coating.
The special coating is a porous
ceramic material which is dark in color
and feels slightly rough to the touch.
If magnified, the surface would
appear as peaks, valleys, and sub-
surface “tunnels.” This rough finish
tends to prevent grease spatters from
forming little beads or droplets which
run down the side walls of a hard-
surface oven liner leaving unsightly
streaks that require hand cleaning.
Instead, when spatter hits the porous
finish it is dispersed and is partially
absorbed. This spreading action
increases the exposure of oven soil to
heated air, and makes it somewhat
less noticeable.
Soil may not disappear completely
and at some time after extended
usage, stains may appear which
cannot be removed.
The special coating works best on
small amounts of spatter. It does not
work well with larger spills, especially
sugars, egg or dairy mixtures.
The special coating is not used on
oven shelves. Shelves should be
cleaned outside the oven to avoid
Jamage to the special coating inside
‘he oven.
GENERAL
To Clean the Continuous — Cleaning
Oven:
1. Let range parts cool before handling.
It is recommended that rubber gloves
be worn when cleaning range parts.
2. Remove shelves and cookware.
3. Soil visibility may be reduced by
operating the oven at 400*F. Close the
door and turn OVEN TEMP knob to
400°F. Time for at least 4 hours.
Repeated cycles may be necessary
before improvement in appearance is
apparent.
REMEMBER: DURING THE OPERA-
TION OF THE OVEN, THE DOOR,
WINDOW AND OTHER RANGE
SURFACES WILL GET HOT ENOUGH
TO CAUSE BURNS. DO NOT TOUCH.
LET THE RANGE COOL BEFORE
REPLACING OVEN SHELVES.
4. If a spillover or heavy soiling occurs
on the porous surface, as soon as the
oven has cooled, remove as much of
the soil as possible using a small
amount of water and a stiff bristle
nylon brush. Use water sparingly and
change it frequently, keeping it as
clean as possible, and be sure to blot
it up with paper towels, cloths, or
sponges. Do not rub or scrub with
paper towels, cloths or sponges, since
they will leave unsightly lint on the
oven finish. If water leaves a white
ring on the finish as it dries, apply
water again and blot it with a clean
sponge, starting at the edge of the
ring and working toward the center.
Do not use soap, detergent, steel
wool pads, commercial oven cleaner,
silicone oven sprays, coarse pads or
coarse brushes on the porous surface.
These products will spot, clog, and
Page B-5
GENERAL
Enamelware: Under some con-
ditions, the enamel of some
cookware may melt. Follow cookware
manufacturer's recommendations for
cooking methods.
mar the porous surface and reduce
its ability to work.
Do not scrape the porous surface
with a knife or spatula — they could
permanently damage it.
RATING PLATE
The rating plate is located under the
lift-up cooktop, or on the front frame
behind broiler drawer. In addition to
model number, and serial number,
the rating plate contains information
regarding ... burner BTU ratings,
electrical rating, gas setting as left
factory, gas conversion, and mini-
mum horizontal clearance to vertical
combustable surface.
MINI-MANUAL
Most self clean ranges contain a
mini-manual. Non-self clean ranges
do not have mini-manuals. Location
of mini-manual:
e Gas manual — behind lower false
panel or drawer
e Microwave (Hi/Low) — In MW Con-
trol Compartment
TOP-OF-RANGE COOKWARE
Aluminum: Medium-weight cook-
ware is recommended because it
heats quickly and evenly. Most foods
brown evenly in an aluminum skillet.
Minerals in food and water will stain
but will not harm aluminum. A quick
scour with a soap-filled wool pad
after each use keeps aluminum cook-
ware looking shiny new. Use sauce-
pans with tight-fitting lids for cooking
with minimum amounts of water.
Cast Iron: If heated slowly, most
skillets will give satisfactory results.
Paye B-6
Glass: There are two types of glass
cookware — those for oven use only
and those for top-of-range cooking
(saucepans, coffee and teapots).
Glass conducts heat very slowly.
Heatproof Glass Ceramic: Can be
used for either surface or oven cook-
ing. It conducts heat very slowly and
cools very slowly. Check cookware
manufacturer's directions to be sure
it can be used on gas ranges.
Stainless Steel: This metal alone has
poor heating properties, and is
usually combined with copper,
aluminum or other metals for
improved heat distribution. Com-
bination metal skillets usually work
satisfactorily if they are used with
medium heat as the manufacturer
recommends.
BAKING PERFORMANCE
To insure good baking performance
a gas oven should be preheated at
least 15 minutes at the cooking
temperature before placing food in
the oven.
e Preheating is very important when
usingtemperatures below 225” F. and
when baking foods such as, biscuits,
cookies, cakes and other pastries.
e Preheating is not necessary when
roasting or for long-time cooking of
whole meals.
IMPORTANT - Two of the most
common customer education types
of baking complaints are:
1. Oven Temperature too low.
2. Takes too long to get oven up
to temperature.
Both problems can usually be
corrected by preheating oven for 15
minutes.
Common Baking Problems and
possible Solutions
Pies
Burning around edges
¢ Oven too full; avoid overcrowding.
e Edges of crust too thin.
e Incorrect baking temperature.
Bottom crust soggy and unbaked
e Allow crust and/or filling to cool
sufficiently before filling pie shell.
e Filling may be to thin or juicy.
e Filling allowed to stand in pie shell
before baking. (Fill pie shells and
bake immediately.)
e Ingredients and proper measuring
affect the quality of the crust. Use a
tested recipe and good technique.
Make sure there are no tiny holes or
tears in a bottom crust. “Patching”
a pie crust could cause soaking.
Pie filling runs over
e Top and bottom crust not well sealed
together.
e Edges of pie crust not built up high
enough.
e Too much filling.
e Check size of pie plate.
Pastry is tough; crust not flaky.
¢ Too much handling.
e Fat too soft or cut in too fine.
Roll dough lightly and handle as little
as possible.
CAKES
Cake rises higher on one side
GENERAL
e Batter spread unevenly in pan.
e Oven shelves not level.
e Using warped pans.
“® Incorrect pan size.
Cakes cracking on top
e Check oven temperature.
e Batter too thick, follow recipe or
exact package directions.
® Check for proper shelf position.
e Check pan size called for in recipe.
® Improper mixing of cake.
Cake falls
e Too much shortening, sugar or
liquid.
¢ Check leavening agent, baking pow-
der or baking soda to assure fresh-
ness. Make a habit to note expira-
tion dates of packaged ingredients.
e Cake not baked long enough or at
correct temperature.
e If adding oil to a cake mix, make
certain the oil is the type and amount
specified.
Crust is hard
e Check temperature
e Check shelf position.
Cake has soggy layer or streaks at
bottom.
e Undermixing ingredients.
e Shortening too soft for proper
creaming.
* Too much liquid.
COOKIES & BISCUITS
Doughy center; heavy crust on
surface
e Check temperature
e Check shelf position.
e Follow baking instructions carefully
as given in reliable recipe or on
convenience food package.
e Flat cookie sheets will give more
even baking results. Don't overcrowd
foods on a baking sheet.
Page B-7
GENERAL
e Convenience foods used beyond
their expiration date.
Browning more noticeable on one
side
* Oven door not closed properly,
check gasket seal.
® Check shelf position.
REMOVEABLE OVEN DOORS
The oven door is user removable on
all range models except for 20"
apartment size, and the top oven
door of Hi-Low ranges.
On some models the doors are
fastened to the hinge supports by
two screws on the inside door panel

SAFETY PRACTICES
SAFETY
In order for the appliance to function
properly, the factory makes a con-
siderable effort to see that a safe
appliance leaves the factory.
However, it must be installed
properly and used intelligently by the
customer.
In spite of all the precautions which
were designed into the range for
safety reasons, we must depend on
properly installed ranges and that the
customer is aware of the proper use
and care.
The information contained in this
section is to remind our service
personnel that the range is safe for
use by the user, and that the user
should be instructed to read the
User's Manual, so that he or she will
be able to operate the range
intelligently and obtain optimum
results.
Page C-1
SAFETY PRACTICES
SERVICE PRACTICES
Safe and satisfactory operation of a
gas range basically depends upon
its design and, to a great extent, upon
proper installation. However, there
is one more area of safety to be
considered: SERVICE.
Listed below are some general
precautions and safety practices
which should be followed in order
to protect the service technician and
the customer during service and after
service has been completed.
1. If you smell gas: Extinguish any
open flame, and open windows.
2. Turn gas off — Perform service to
range with gas turned off unless
needed for testing.
3. Checking for gas leaks — Never
check for leaks with a match, or
any other kind of open flame. A
soap and water (suds) solution
should be used for this purpose.
Apply suds to the suspected area,
and watch for air bubbles which
indicate a leak. Correct leaks by
tightening fittings, screws, con-
nections, applying approved com-
pound, or by installing new parts.
4. Using lights — Use hand flashlights
only when servicing a range or
checking for gas leaks. Electric
switches should not be operated
where leaks are suspected. (This
will avoid creating arcing or sparks
which could ignite the gas). If elec-
tric lights are already turned on,
they should not be turned off.
Page C-2
5. Do not smoke - Do not smoke
while servicing a gas range,
especially if working on piping or
components which contains or has
contained gas.
6. Check range when service
completed —- After service has
been completed, make electrical
connection, relight all pilots, and
check for leaks. Advise customer
of condition of range before
leaving.
7. Adhere to all local regulations and
codes when performing service.
CUSTOMER USAGE PRACTICE
IMPORTANT SAFETY INSTRUCTIONS
These safety instruction are in the
customer's use and care manual.
When You Get Your Range
o Have the installer show you the
location of the range gas cut-off
valve and how to shut is off if
necessary.
e Have your range installed and
properly grounded by a qualified
installer, in accordance with the
Installation Instructions. Any
adjustment and service should be
performed only by qualified gas
range installers or service
technicians.
* Plug your range into a 120-volt
grounded outlet only. Do not remove
the round grounding prong from the
plug. If in doubt about the grounding
of the home electrical system, it is
your personal responsibility and
obligation to have an ungrounded
outlet replaced with a properly-
grounded three-prong outlet in
accordance with the National
Electrical Code. Do not use an
extension cord with this appliance.
* Be sure all packing materials are
removed from the range before
operating it, to prevent fire or smoke
damage should the packing mater-
ial ignite.
* Be sure your range is correctly
adjusted by a qualified service
technician or installer for the type
of gas (Natural or LP) on which it is
to be used. Your range can be
converted for use on one type of gas
SAFETY PRACTICES
or the other. See Installation
Instructions.
e After prolonged use of a range, high
floor temperatures may result and
many floor coverings will not with-
stand this kind of use. Never install
the range over vinyl tile or linoleum
that cannot withstand such type of
use. Never install it directly over inter-
ior kitchen carpeting.
Using Your Range
e Don't leave children alone or unat-
tended where a range is hot or in
operation. They could be seriously
burned.
e Don't allow anyone to climb, stand
or hang on the door or range top.
They could damage the range and
even tip it over causing severe
personal injury.
e CAUTION: ITEMS OF INTEREST TO
CHILDREN SHOULD NOT BE
STORED IN CABINETS ABOVE A
RANGE OR ON THE BACKSPLASH
OF ARANGE- CHILDREN CLIMBING
ON THE RANGE TO REACH ITEM
COULD BE SERIOUSLY INJURED.
e Let burner grates and other sur-
faces cool before touching them or
leaving them where children can
reach them.
e Never wear loose fitting or hanging
garments while using the appliance.
Flammable material could be ignited
if brought in contact with flame or
hot oven surfaces and may cause
severe burns.
e Never use your appliance for
warming or heating the room.
Prolonged use of the range without
Page C-3
SAFETY PRACTICES
adequate ventilation can be
hazardous.
* Do not use water on grease fires.
Never pick up a flaming pan. Turn
off burner, then smother flaming pan
by covering pan completely with well
fitting lid, cookie sheet or flat tray.
Flaming grease outside a pan can
be put out by covering with baking
soda or, if available, a multi-purpose
dry chemical or foam fire
extinguisher.
e Do not store flammable materials
in an oven or near the cooktop.
* Do not let cooking grease or other
flammable materials accumulate in
or near the range.
* When cooking pork, follow our
directions exactly and always cook
the meatto atleast 170°F. This assures
that, in the remote possibility that
trichina may be present in the meat,
it will be killed and meat will be safe
to eat.
Surface Cooking
e Always use the LITE position when
igniting top burners and make sure
the burners have ignited.
e Never leave surface burners
unattended at HI flame settings.
Boilover causes smoking and greasy
spillovers that may catch on fire.
* Adjust top burner flame size so it
does not extend beyond the edge
of the cooking utensil. Excessive
flame is hazardous.
* Use only dry potholder — moist or
damp potholders on hot surfaces
Page C-4
may result in burns from steam. D'
not let potholders come near ope
flames when lifting utensils. Do nc
use a towel or other bulky cloth i
place of a potholder.
® То minimize the possibility of burns
ignition of flammable materials, an:
spillage, turn the cookware handle
toward the side or back of the rang
without extending over adjacen
burners.
e Always turn surface burner to OF
before removig utensil.
e Carefully watch food being fried a
HI flame setting.
e Never block the vents (air openings
of the range. They provide the ai
inlet and outlet which is necessar
for the range to opereate proper!
with correct combustion.
* Do not use a wok on the cooking
surface if the wok has a round meta
ring which is placed over the burne
grate to support the wok. This ring:
acts as a heat trap which ma
damage the burner grate and burne
head. Also, it may cause the burne
to work improperly. This may caus
a carbon monoxide level above tha
allowed by current standards
resulting in a health hazard.
e Food for frying should be as dry a
possible. Frost of frozen foods o
moisture on fresh foods can caus
hot fat to bubble up and over side:
of pan.
e Use least possible amount of fatfo
effective shallow or deep-fat frying
Filling the pan too full of fat car
cause spillovers when food is added
e |f a combination of oils or fat will
be used in frying, stir together before
heating, or as fats melt slowly.
* Always heat fat slowly, and watch
as it heats.
* Use deep fat thermometer when-
ever possible to prevent overheating
fat beyond the smoking point.
* Use proper pan size — Avoid pans
that are unstable or easily tipped.
Select utensils having flat bottoms
large enough to properly contain
food avoiding boilovers and
spillovers, and large enough to cover
burner grate. This will both save
cleaning and prevent hazardous
accumulations of food, since heavy
spattering or spillovers left on range
can ignite. Use pans with handles
that can be easily grasped and
remain cool.
¢ Use only glass cookware that is
recommended for use on gas
burners.
e Keep all plastics away from top
burners.
* To avoid the possibility of a burn,
always be certain that the controls
for all burners are at OFF position
and all grates are cool before
‘attempting to remove a grate.
® When flaming foods under the
hood, turn the fan off. The fan, if
operating, may spread the flame.
e |f range is located near a window,
do not use long curtains which could
blow over the top burners and create
a fire hazard.
e |f you smell gas, turn off the gas to
SAFETY PRACTICES
the range and call a qualified service
technician. Never use an open flame
to locate a leak.
Baking, Broiling and Roasting
e Do not use oven for a storage area.
e Stand away from the range when
opening the door of a hot oven. The
hot air or steam which escapes can
cause burns to hands, face and/
or eyes.
e Don’t heat unopened food con-
tainers in the oven. Pressure could
build up and the container could
burst causing an injury.
e Don't use aluminum foil anywhere
in the oven except as described in
this book. Misuse could result in a
fire hazard or damage to the range.
e Use only glass cookware that is
recommended for use in gas ovens.
e When using cooking or roasting
bags in oven, follow the manu-
facturer's directions.
* Always remove broiler pan from the
oven as soon as you finish broiling.
Grease left in the pan can catch fire
if oven is used without removing the
grease from the broiler pan.
¢ When broiling, if meat is too close
to the flame, the fat may ignite. Trim
excess fat to prevent excessive
flare-ups.
* Make sure broiler pan is in place
correctly to reduce the possibility of
grease fires.
e |f you should have a grease fire in
the broiler pan, turn off oven, and
Page C-5
SAFETY PRACTICES
keep oven door closed to contain fire
until it burns out.
Self-Cleaning Oven
* Do not clean the door gasket. The
door gasket is essential for a good
seal. Be careful not to rub, damage
or move it.
* Do not use oven cleaners. No
commercial oven cleaner or oven
liner protective coating of any kind
should be used in or around any part
of the oven.
* Remove the broiler pan and other
cookware before self-cleaning
the oven.
INSTALLATION
NOTE: IN SOME CASES. THE
POWER CORD OF THE RANGE IS
DRAPED AROUND THE OVEN VENT
ASSEMBLY WHEN THE RANGE IS
UNCRATED. BE SURE TO UNWRAP
THE CORD FROM THE OVEN VENT
BEFORE YOU INSTALL THE RANGE.
PROVIDE ADEQUATE GAS SUPPLY
This range is designed to operate
on natural gas at 4” of water column
pressure or on LP gas at 10" of water
column pressure. It is shipped from
the factory set for natural gas. If it
is to be used with LP gas, adjust-
ments must be made (see Gas
Conversions).
A convertible pressure regulator is
connected in series with the manifold
of the range and must remain in
series with the supply line regard-
less of whether natural or LP gas is
being used.
Page C-6
FOR PROPER OPERATION; THE
MAXIMUM INLET PRESSURE TO
THE REGULATOR MUST BE NO
MORE THAN 14" OF WATER
COLUMN PRESSURE. For checking
the regulator, the inlet pressure must
be at least 1” greater than the
regulator output setting. If the
regulator is set for4” of water column
pressure, the inlet pressure must be
at least 5”. If the regulator is set for
10”, the inlet pressure must be at
least 11”.
The gas supply line into the range
should be a %" or 34" |.D. flexible
metal appliance connector five feet
in length.
SEAL THE OPENINGS
Seal any openings in the wall behind
the range and in the floor under the
range when hookups are completed.
CONNECT THE RANGE TO GAS
Install a manual shut-off valve in the
gas line in an easily-accessible
location outside of the range. Be sure
you know and where to shut-off the
gas supply to the range.
ELECTRICAL REQUIREMENTS:
120-volt, 60 Hertz, individual,
properly grounded branch circuit
protected by a 15 amp. circuit breaker
or time delay fuse.
Extension Cord Cautions:
Because of potential safety hazards
under certain conditions we strongly
recommend against the use of an
extension cord. However, if you still
elect to use an extension cord. It is
absolutely necessary that it be a UL
listed 3-Wire grounding type appli-
ance extension cord and that the
current carrying rating of the cord in
amperes be equivalent to or greater
than the branch circuit rating. Such
extension cords are obtainable
through your local service
organization.
GROUNDING
IMPORTANT: (Please read carefully).
FOR PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY
GROUNDED.
The power cord of this appliance is
equipped ith a three-prong (ground-
ing) plug which mates with a
standard three-prong grounding wall
receptacle to minimize the possibility
of electric shock hazard from this
appliance.
The customer should have the wall
receptacle and circuit checked by a
qualified electrician to make sure the
receptacle is properly grounded.
PREFERRED METHOD
INSURE PROPER GROUND
EXISTS BEFORE USE.
Where a standard two-prong wall
receptacle is encountered, it is the
personal responsibility and obliga-
tion of the customer to have it
replaced with a properly grounded
three-prong wall receptacle. DO NOT,
UNDER ANY CIRCUMSTANCES,
CUT OR REMOVE THE THIRD
(Art Nos. WB983,984)
SAFETY PRACTICES
(GROUND) PRONG FROM THE
POWER CORD.
USAGE SITUATIONS WHERE THE
APPLIANCE POWER CORD WILL BE
DISCONNECTED INFREQUENTLY
For 15 amp. circuits only. Do not use
an adapter on a 20 amp. circuit.
Where local codes permit, a
TEMPORARY CONNECTION may be
made to a properly grounded two-
prong wall receptacle by the use of
a UL listed adapter available at most
hardware stores
The larger slot in the adapter must
be aligned with the larger slot in the
wall receptacle to provide proper
polarity in the connection of the
power cord.
TEMPORARY METHOD
(ADAPTER PLUGS NOT
PERMITTED IN CANADA)
ALIGN LARGE PRONGS/SLOTS.
a
INSURE PROPER GROUND
AND FIRM CONNECTION
BEFORE USE.
CAUTION: ATTACHING THE
ADAPTER GROUND TERMINAL
TO THE WALL RECEPTACLE
COVER SCREW DOES NOT
GROUND THE APPLIANCE
UNLESS THE COVER SCREW IS
METAL, AND NOT INSULATED,
AND THE WALL RECEPTACLE
IS GROUNDED THROUGH THE
HOUSE WIRING. THE CUSTO-
MER SHOULD HAVE THE
CIRCUIT CHECKED BY A
QUALIFIED ELECTRICIAN TO
MAKE SURE THE RECEPTACLE
IS PROPERLY GROUNDED.
Page C-7
SAFETY PRACTICES
When disconnecting the power cord
from the adapter, always hold
adapter with one hand. If this is not
done, the adpater ground terminal
is very likely to break with repeated
use. Should this happen, DO NOT
USE the appliance until a proper
ground has again been established.
USAGE SITUATIONS WHERE
APLIANCE POWER CORD WILL BE
DISCONNECTED FREQUENTLY.
Do not use an adapter plug in these
situations because disconnecting of
the power cord places undue strain
on the adapter and leads to eventual
failure of the adapter ground
terminal. The customer should have
the two-prong wall receptacle
replaced with a three-prong
(grounding) receptacle by a qualified
electrician before using the
appliance.
Installing the Range
Your range, like so many other
household items, is heavy and can
settle into soft floor coverings such
as cushioned vinyl or carpeting.
When moving the range on this type
of flooring, use care.
Do not install the range over kitchen
carpeting unless you place an
insulating pad or sheet of
Va-inch-thick plywood between the
range and carpeting.
When the floor covering ends at the
front of the range, the area that the
range will rest on should be built up
with plywood or similar material to
the same level or higher than the
floor covering. This will allow the
range to be moved for cleaning or
servicing.
Leveling the Range
Your range must be level in order to
produce proper cooking and baking
Page C-8
*
result. After it is in its final location,
place a level horizontally on an oven
shelf and check the levelness front
to back and side to side. Level the
range by adjusting the leveling legs
or by placing shims under the
corners as needed.
SAFETY PRACTICES
PRODUCT SAFETY DEVICES
Safety devices and features have been engineered into the product to protect
the user and the servicer. Safety devices must never be removed, by-passed,
or altered in such a manner as to defeat the purpose for which they were
intended.
Listed below are various safety devices together with the reason each device
is incorporated in the gas range.
Pressure Regulator Maintains proper and steady gas pressure for
operation of range controls. The regulator must be
set for the type of gas being used — natural or LP.
After servicing the regulator make certain it is set
properly before completing service.
Gas Burner Orifices Universal orifices are used on top burner valves and
oven valves. They must be adjusted or set for the
type of gas being used — natural or LP.
After servicing a valve or orifice make certain it is
adjusted properly before completing service.
Oven Safety Valve The oven valve is designed to be a safety valve. Two
basic designs are used in gas ranges.
Hydraulic type valve
Electric type valve
Both types are safety valves because they are indirectly
operated by the oven thermostat, which controls a
pilot flame or electric ignitor, to open and close the
oven valve.
Latch Assembly Locks the door during self cleaning cycle. Prevents
| possible injury to user by preventing door opening at
high temperatures where ignition of soil could take
place with the in-rush of air.
Grounded Range The ground prong of the gas range electric power
Frame cord is connected to the range frame-usually a green
lead fastened by a screw. In addition, any part or
component capable of conducting an electric current
is grounded by it's mounting.
If any ground wire, screw, strap, nut, etc. is removed
for service, or any other reason, it must be reconnected
to it's original position with the original fastener before
the appliance is put into operation again.
Failure to do so can create a possible shock hazard.

GAS DISTRIBUTION SYSTEMS AND COMPONENTS
THREE DISTRIBUTION SYSTEMS
GE and Hotpoint Gas Ranges have been sourced from several different
GAS Range Manufacturers — see model section for model numbers and
source listing. Other pertinent component information may also be iden-
tified in the listing.
Regardless of Gas Range manufacturer, there are three (3) basic types of
gas distribution systems used:
1. STANDING PILOT - COOKTOP AND OVEN
2. ELECTRIC IGNITION — COOKTOP AND OVEN (SPARK TYPE)
3. ELECTRIC IGNITION — COOKTOP (SPARK), OVEN (GLOWBAR)
NOTE: All Built-In Cooktops, Wall Ovens, and Hi/Low Top Ovens have
electric ignition:

GAS DISTRIBUTION SYSTEMS AND COMPONENTS
STANDING PILOT - TOP & OVEN
The gas supply line is connected to
the range pressure regulator which
is connected to the manifold.
NOTE: Depending on model, the
regulator is located at the end of the
manifold under the cooktop, or is
located behind the range and con-
nected to the manifold by a sepa-
rate tube. (See pressure regulator).
From the manifold gas is distributed
to the top burners through burner
valves, and to the oven burner
through the thermostat and oven
valve.
NOTE: Depending on model, the sur-
face or top burners connect directly
over the orifices on the end of the
top valves, or to separate orifices on
the bottom of the burner box and
connected to the top valves by sepa-
rate tubes. (see top burners).
Page D-2
The oven thermostat mounts to the
manifold, and it has two tubes which
go to the oven. The larger tube goes
to the oven valve, and the smaller
tube goes to the pilot assembly. A
small amount of gas supplies the
standing, or primary, pilot. When the
thermostat is turned to a cooking
temperature, a larger amount of gas
goes through the pilot tube and the
flame enlarges to a secondary pilot
The oven valve sensor senses this
secondary pilot flame, and the over
valve turns on gas to the oven burn.
er after about 30 seconds. Gas is
supplied directly to the oven valve
when the thermostat is turned to ar
“on” position.
STANDING PILOT COMPONENTE
Components associated with stand
ing pilot systems are outlined ir
the following information.
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
TOP BURNER PILOTS
The two top pilots and the oven pilot
must be match lit initially. The top
pilots are located between each pair
of burners. Raise the cooktop for
access to the pilots. The pilot flame
should be 1” or less if possible, with
a slight yellow tip. (see note) Adjust
the pilot by the adjusting screw on
the pilot filter.
NOTE: If pilot is too low, top burner
ignition may not occur. If the pilot is
too high, carbon (soot) will accum-
ulate under the cooktop and cooktop
may rust.
The pilot filter and adjust screw is
located under the cooktop.

OVEN STANDING PILOT
The oven pilot assembly works in
conjunction with the oven thermo-
stat, and oven safety valve.
Oven pilot and oven burner gas is
controlled by the thermostat. When
the thermostat is “off’’ all oven gas
is off. When the thermostat is set to
some temperature, gas flows to the
oven pilot and to the oven safety
valve.
(Art No. WB1375)
The oven valve is a hydraulic type
with a mercury-filled bulb which
mounts to the oven pilot assembly.
Gas is always flowing to the oven
pilot assembly to provide a stand-
ing pilot.
When the thermostat is turned “ON”
to any temperature setting, additional
pilot gas flows through the small
pilot line to the pilot assembly.
Immediately the standing pilot flame
should enlarge and extend down the
pilot assembly to engulf the bulb of
the oven safety valve. At the same
time, gas will flow through the large
line from the oven thermostat to the
oven valve. The valve however, is
closed to the oven burner until the
pilot flame (heater pilot) heats the
oven valve bulb enough to open the
oven valve and allow gas to flow to
the oven burner.

Oven Pilot Flame Adjustment
The oven standing pilot flame size
is not adjustable as such. If the pilot
does not extend down the pilot
assembly to engulf the oven valve
bulb when the thermostat calls for
“TURN ON,” then check the
following:
1. Turn oven thermostat to “OFF”
position.
2. Turn off range gas supply.
Page D-4
2. Disconnect pilot gas line at
thermostat and at pilot assembly
— blow through the tubing to clear
out any obstruction.
4. Remove the pilot assembly and
locate the hole in its side in front
of the pilot orifice. Carefully insert
a pocket size screwdriver in the
hole and push the “hat shaped”
orifice out of the pilot body — blow
through the orifice to clear any
blockage of the orifice — the orifice
is oniy .014” in size. Do not enlarge
the orifice.
5. Make certain pilot select screw is
set for type of gas being used.
Oven Thermostats
Two different type thermostats were
used on standing pilot ranges.
e “Robertshaw ELO” — used on
Tappan, Magic Chef, 8
Hardwick models
® “Harper/ Wyman — used on
Glenwood/Caloric models
Both types are basic gas hydraulic
type thermostats in which the stem
and core act as a manual shut off
valve for gas to the oven valve.
Robertshaw ELO Thermostat
Two things should be noted about
the “Robertshaw Model ELO"
thermostat used on the standing
pilot ranges:
1. To prevent pilot outage when the
thermostatis turned “on”, a small
orifice inside the thermostat
connects the main oven valve
chamber and outlet with the pilot
outlet. Withoutthisorificetherush
of gas into the thermostat inlet
would tend to lower pressure for
the gas going down to the small
standing pilot flame.

Typical electric ignition model with spark system — cooktop &

(Art No. WB1503) Page D-5
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
The gas supply line connects to the
pressure regulator which is con-
nected to the manifold.
NOTE: Depending on model, the
regulator is located under the cook-
top, or behind the range and is con-
nected to the manifold by a separate
tube. (See Pressure Regulator).
From the manifold gas is distributed
to the top burners through burner
valves, and to the oven burner
through the thermostat and oven
valve.
NOTE: Depending on model, the sur-
face or top burners connect directly
over the orifices on the end of the
top valves, or to separate orifices on
the bottom of the burner box and
connected to the top valves by sepa-
rate tubes. (See Top Burners).
The surface burner valves have elec-
tric ignition switches. The thermo-
stat is very much like the one used
on standing pilot models. The only
differences are: (a) No gas flows
through the oven thermostat (for a
standing pilot flame) when it is in
its “OFF” position, and (b) An elec-
tric ignition switch for the ovem pio
is mounted on the thermo tat sf
When the thermostat is turned from
“OFF” to any cooking temperature,
gas flows through the oven pilot tube
to the pilot assembly. At the same
time, the thermostat electric ignition
switch closes and this causes spark-
ing of the oven electric igniter, which
ignites the oven pilot secondary
flame.
Page D-6
The secondary pilot flame size is the
same as for the standing pilot sys-
tem. The hydraulic oven valve sen-
sor senses the secondary pilot flame,
and this turns on gas to the oven
burner after about 30 seconds.
The oven valve and oven pilot assem-
bly is identical to the ones used on
standing pilot models, and they oper-
ate the same — except no pilot flame
is present until the oven thermostat
Is turned “on” to some temperature
setting. The thermostat then cycles
the pilot flame from a standing pilot
size to a heater pilot size, to operate
the valve and burner.
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
Oven Thermostats
Two different type thermostats.
e “ROBERTSHAW ELO - Tappan,
Magic Chef, and Hardwick models.
e “HARPERWYMAN"” — Glenwood/
Caloric Models.
Important —- These thermostats are
not interchangeable with standing
pilot model thermostats.
Robertshaw ELO Thermostat
If the temperature is set above 400
degrees, when the temperature is
reached, the oven burner flame is
modulated down rather than going
off. The burner flame then cycles
from the low modulated flame to full
size to maintain an even temperature.
Electric Ignition —- Spark System
Top and oven (2 + 1)
This spark ignition system consists
of a solid state module, three
electrodes (2 for top burners & 1 for
the oven), and five switches to
energize the circuit — there is one
switch for each top burner valve and
one for the oven thermostat.
Note: This system is commonly
called 2 + 1 spark ignition.
The module is powered by 120 volts.
All input and output wiring connec-
tions are marked on the body of the
module.
Two different types (manufacturers)
of modules have been used (KIGASS
& HARPER/WYMAN). Both types
operate the same electrically, but are
not interchangeable due to mount-
ing. The terminal legends for each
type are as follows:

The module contains an electronic
circuit and pulse transformer within
the module which produces periodic
high voltage pulses to all electrodes
at a rate of approximately 2 pulses
(sparks) per second. The high voltage
pulses are about 13.5 KV but presents
no serious shock hazard because of
the very low current (3-4 milliamps).
CAUTION: While there is no serious
shock hazard involved, it should be

Two spark electrodes (ignitors) are
used for the top burners, one for each
pair of burners. The electrode is

IGNITION SWITCH
The top burner valve is a standard
type valve with a special micro
switch located on the shaft. The
switch terminals are on each side.
The hub of the switch rotates with
shaft to turn the switch “on” when
the knob is set at the “lite “ position.
When any switch is closed all
electrodes spark.
After the top burner is lit and the
knob is moved from the “lite”
position, the switch opens and the
sparking stops.
The switches merely slip over the
valve shaft, therefore service to the
switch is simple. The switches can
be continuity tested by removing the

terminals while turning the valve to
the “lite” position. Caution: Gas will
be flowing from the valve during the
test. Turn valve to “off” as soon as
possible.

Oven Burner Spark Ignition
The thermostat also uses an ignition
switch on the shaft. This switch
closes when the shaft is at any set-
ting execept “off” — There is no
“lite” position like on top burner
valves.
When the knob is turned to a
temperature setting, pilot gas flows
and the oven electrode “sparks’’ until
the pilot ignites. The electrode senses
the presence of the pilot flame and
stops “sparking” due to reduced cir-
cuit resistance. (Remember, when
the oven electrode ‘’sparks,’’ the
top burner electrodes do also, and
vice versa.)
OVEN PILOT ASM.
PILOT SENSING BULB
(OVEN VALVE)
ELECTRODE
The pilot assembly mounts to the
side of the oven burner and houses
the oven electrode and sensing bulb
of the oven safety valve. The oven
thermostat controls the gas flow to
the pilot. When the ovenis calling for
(Art Nos. WB1375,1622)
heat, the pilot flame is elongated and
envelops the safety valve bulb.
The safety valve opens and allows
main gas to the burner. When the
oven is at set temperature, the
elongated pilot flame reduces to a
small primary pilot flame — the
safety valve then closes.
NOTE: The oven has a reignition
(REIG) feature — if the oven pilot
blows out, the oven electrode will
automatically “spark” again to re-
light the pilot.

(Tappan self clean “J” model shown)
Page D-14 (Art No. WB1503)
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
This system uses spark ignition for
top burners, and a glowbar igniter
for the oven.
The gas supply line connects to the
pressure regulator which is con-
nected to the manifold
NOTE: Depending on model, the
regulator is located under the cook-
top, or behind the range and is con-
nected to the manifold by a separate
tube. (see pressure regulator)
From the manifold gas is distributed
to the top burners through burner
valves. Gas flow to the oven is
through an on-off valve mounted to
the manifold, (or on the pressure
regulator), and then directly to an
electric open valve. The oven ther-
mostat is electric and therefore has
no gas connections to it.
NOTE: Depending on model, the top
burners connect directly over the ori-
fices on the end of the top valves, or
‘to separate orifices on the bottom
of the burner box and connected to
the top valves by separate tubes. (see
top burners)
Top Burner Spark Ignition
This spark ignition system consists
of a solid state spark module, two
electrodes (spark igniters), and four
valve switches. To energize the circuit
— each top burner valve has its own
separate switch.

TOP BURNER SPARK IGNITION CIRCUIT
(Art No. WB1622)
Typical Top Burner (only) Spark
System
The spark module contains an
electronic circuit which produces
periodic high voltage pulses (apprx.
2 sparks per second) to both top
burner electrodes when the module
input is connected to the 120 volt
supply.
The module has four terminals:
| & N— 120 Volt Input
1 & 2- High voltage output leads to
spark electrodes.
The four top burner igniter switches
are connected in parallel in the line
(L) input. Each switch mounts on the
valve shaft. When a top burner valve
knob is turned “on” to the “lite”
position, the switch contacts close
and connects 120 volt power to the
spark module.
When 120 volts is supplied to the
module, the output at terminals “1”
to “2”, provides a high voltage pulse
which creates a spark between each
of the two spark gap electrodes and
ground. The spark then ignites the
burner. After the top burner is lit and
the knob is moved from the “lite”
position, the switch opens and the
sparking stops.

OVEN IGNITION
GLOW-BAR IGNITER
An oven glow-bar igniter mounts
parallel or adjacent to the oven
burner and, with voltage applied,
can reach temperatures in excess
of 2000 degrees F, which is well
above the temperature required to
ignite the burner gas.
The typical glow-bar ignition system
consists of a series circuit of the fol-
lowing components:
e Electric glow-bar igniter
e Electric gas valve
e Electric oven thermostat
Other components such as an oven
select switch, timer contacts, etc,
may be used, but does not change
the basic circuit operation. (Refer to
range schematic/wiring diagram for
details.

*TAPPAN MODELS ONLY 1.30
TYPICAL GLOWBAR IGNITION CIRCUIT
When the thermostat is turned to
cooking temperature, the switch con-
tacts close and applies 120 volts
across the series circuit. Current
flows through the glow-bar and
through the bi-metal heater coil
inside the oven valve which is nor-
mally closed. As the glow-bar heats
up, its resistance decreases, and
more current flows.
The gas oven valve is current oper-
ated and will not open until the ser-
ies circuit current increases to the
minimum operating current of the
valve.
(Art No. WB1622)
Important - Two different types of
glow-bar igniters (and matching val-
ves) have been used, and the min-
imum operating currents are
different:

dum (2.5-3.0A)
*¥Used on most ovens
NORTON GLOWBAR
CARBORUNDUM GLOWBAR
When the current reaches the oper-
ating range, the valve opens and
allows gas to flow to the oven bur-
ner which ignites. This generally
takes 30-60 seconds from cold start.
The glow-bar will cycle “on” and
Page D-17
. GAS DISTRIBUTION SYSTEMS AND COMPONENTS
“off” as the thermostat cycles to
maintain oven temperature.
CAUTION:
The glow-bar may glow red and
appear to be operating properly, but
the current through the series cir-
cuit may be too low to allow the
oven valve to operate. For a non-
ignition complaint, always check the
current through the glow-bar with
a clamp-on amp probe. THE CUR-
RENT MUST BE AT LEAST THE MIN.
CURRENT FOR THE TYPE OF GLOW-
BAR IN USE. If not — replace the glow-
bar not the valve.
Glow-Bar Igniter Service
Since the glow-bar igniter must be
located adjacent to the oven burner,
the igniter can be serviced by remov-
ing the oven bottom and burner baf-
fle. The igniter is usually mounted
to a bracket by two screws.
NOTE: Ovens with a separate bake
and broil burner will have separate
igniters. The broil igniter can be ser-
viced by removing the broil burner
baffle.
OVEN ELECTRIC GAS VALVE
An electrically operated oven gas
valve is used on all range ovens that
have a glow-bar ignition system. The
gas valve supplies gas to the oven
burner. For most ranges, which have
only one burner, the gas valve is
located directly under the oven
burner, and contains the burner ori-
fice and a single inlet gas line from
a shut-off valve.

Pressure Regulator
The pressure regulator is the heart
of the range operation.
The range controls and burners are
designed to operate at a steady
pressure for the type of gas in use —
Natural or LP.
A pressure regulator can only de-
crease the pressure — it cannot in-
crease it.
A typical pressure reguator is divided
into two (2) main sections — upper
and lower and are isolated and sep-
arated by a spring loaded diaphragm.
The gas flow is through the lower
section; and air and spring tension
in the top.

High pressure gas enters the inlet
end and passes through an opening
to the regulated lower gas pressure
outlet. The spring loaded diaphragm
moves up and down automatically
as needed to maintain a steady flow
and outlet pressure. The spring ten-
sion must be set for the type of gas
in use.
Important: For proper operation, the
input pressure must be at least 1”
higher than the regulated output
pressure.
{Art Nos. WB1375,1622)
Different types of regulators are used
and method of setting will therefore
be different. In any case LP gas
setting requires more spring tension
than natural.
(NOTE: Exposed end of cap and
plunger is marked NAT or LP)

ORIFICES
All range models use universal ori-

can be used on natural or LP gas.
A hollow needle in the end of the
valve allows gas to pass through it
and around it as long as the orifice
cap is not seated against the needle.
When the orifice cap is screwed
down against the needle, gas can
pass through the center of the nee-
die only. This feature therefore makes
the orifice adjustable so it can be
used on natural or LP gas.
Natural Gas — The orifice cap must
be unscrewed away from the needle
to allow gas to flow around the nee-
die as well as through it.

TOP BURNER VALVES
Top burner valves are basically two
types:
e Continuous or 90° Valves
e Hi-Med-Sim-Wm or 225° Valves
Both Types Are “Push-To-Turn”
Either type may be used on stand-
ing pilot or electric ignition type
ranges. In either case their opera-
tion is basically the same.
To Use:
e Standing Pilot Models — turn knob
to “Hi” or “Lite” position until burn-
er ignites, then turn knob to flame
size desired.
o Electric Ignition Models - Turn
knobto “Lite” position— pilotignitor
Will “spark”. When burner ignites,
turn knob to desired flame size.
(Art Nos. WB1450,1622)
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
90° Valve Operation
The 90° valve is very simple in con-
struction and operation. It can ro-
tate only 90°. The valve ‘stem’ has a
large opening or orifice which allows
gas to pass from the manifold
through the valve body and out the
orifice in the end of the orifice hood.

When the valve is in the “Off” posi-
tion, the stem hole is not in line with
valve body hole and no gas can flow.
When the valve is turned to “Hi”, all
of the stem hole is exposed for max-
imum gas flow. As the valve is turn-
ed less of the hole is exposed and
therefore less gas flow, and a small
flame.
225° Valves
This valve rotates about 225° as it has
several marked settings — HI, MED,
SIM, and WM.
The valve is constructed and oper-
ates exactly as the 90° valve except it
has three (3 separate holes or orif-
ices in the valve stem to provide all
of the settings.

Top Burner “Warm” Adjustment
Some top burner valves have a
“warm” setting which can be
adjusted.
To Adjust:
1. Turn knob to “lite” position until
burner ignites.
2. Quickiy turn knob to “warm”
burner flame should reduce to
small size but should not go out.
If burner goes out - remove knob and
adjust small screw in valve shaft to
increase or decrease the flame size
at “warm”. Adjust until the flame is
as small as possible without extin-
guishing when the valve is quickly
turned from “lite” to “warm”.
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
TOP BURNERS
WITH AIR ADJUSTMENT
All ranges, except Tappan “J’’ mod-
els, have adjustable air shutters on
the top burners.
Air Adjustment
An air adjustment shutter for each
surface burner regulates the flow of
air to the flame.
When the right amount of air flows
into the burner, the flame will be
steady, relatively quiet and have
approximately 34" sharp blue cones
without yellow tips. This usually
results when the shutter is about
halfway open.
With too much air, the flame will be
unsteady, possibly won't burn all
the way around, and wili be noisy,
sounding like a blowtorch.
With not enough air, you won't see
any sharp blue cones in the flame,
you may see yellow tips, and soot
may accumulate on pots and pans.
Loosen
/
Air Adjustment Shutter
The air adjustment shutters set on
the hood of the valve and are either
Page D-24
locked in place with Phillips head
screws or positioned on the burner
tubes by friction fit.
To adjust the flow of air to the burn-
ers, loosen the Phillips head screws
and rotate the shutters (or apply a
blade-type screwdriver against the
friction-fit shutters and push) to allow
more or less air into the burner tubes
as needed.

The valves are mounted to the man-

run under the burner box from each
valve to bring gas to the orifices. The

orifices are located in the bottom of
the burner box, one directly under
each surface burner head.
The orifice size of the hood is num-
ber 54 drill for NAT gas. The orifice
size of the inner needle is number

When gas leaves the orifice of the
mixer elbow it passes through the
air, and is injected into the bottom
of the top burner head. As the gas
passes between the orifice and the
burner head, air is mixed with gas
to form a combustible mixture. The
burner head disperses the gas air
mixture from around the top for the
burner flame, and from ports on the
side for ignition. The two lower ports,
on the side of the burner head, inject
gas down the flash tube to be igni-
ted by the pilot. The other three ports
one side to the burner head are to
allow the flame to climb the side of
the burner head to ignite the burner
gas.

(Art No. WB1503)
The reasons that no air shutter is
required for this system are:
1. The tolerances in the dimensions
and alignment of the orifice open-
ing to the bottom of the burner
head are controlled very tightly.
On prior designs, the air shutter
was needed to compensate for
dimension and alignment differ-
ences from orifice opening to the
end of the burner venturi tube.
2. The dimensions were designed
to give good performance on LP
gas, which is more critical than
NAT gas. Therefore, when the ori-
fice is set up for NAT gas, the per-
formance remains good.
The most critical dimension is the
distance from orifice to the bottom
of burner head. The most critical
alignments are (a) centering of ori-
fice to centerline of burner head, and
(b) vertical alignment of orifice spud.
If there are problems with the sur-
face burner flame, check that the
burner head has not been pushed
down, and that the orifice spud is
vertical and centered under the
burner head.
NORMAL TOP BURNER OPERATION
The following information appears in
the user book.
“Due to the unique design on the
top burners, you may at times exper-
ience a blowing or hissing sound
when burners are intially turned on.
This is a normal condition which is
due to improved injection of gas and
air into top burner and should not
be cause for concern. It does not
require a service call.
Page D-25
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
The blowing or hissing will occur for
a period of 30 to 45 seconds or until
burner heats up.
When a cooking vessel is placed on
top grate prior to turning on burner
or if burner flame is adjusted to
accommodate pan size, blowing or
hissing sound is greatly diminished.
Illustration 41 indicated how flames
would appear after initial turn on.
Flame would have slight lifting away
from burner and would be approx-
imately horizontal.
Illustration #2 indicates how flames
will appear after heat up or 30 to 45
seconds after turn on. Flames will
stabilize and curve upwards.”

OVEN THERMOSTATS
Gas range thermostats are basically
one of two types:
¢ Hydraulic gas type — with gas
connection
e Hydraulic electric type — no gas
connection
The hydraulic gas type thermostat is
used on non-self clean standing pilot
models and non-self clean spark
ignition oven models... these
Page D-29
GAS DISTRIBUTION SYSTEMS AND COMPONENTS
models use a hydraulic type oven
burner valve. The electric type ther-
mostat is used on ranges which have
‘“glow-bar’’ oven igniters — this
includes some non-self clean models
and all self-clean models ... these
models use an electric type oven
burner valve.
It is important to be aware that the
heating and temperature char-
acteristics vary considerably from
one manufacturers range to another.
These variations mainly involve the
initial heat-up, or bake preheat time
of the oven... this can be critical to
baking performance.
Important: In general, with foods
which require preheating, the oven
should be preheated for 15 minutes
before placing food in the oven.
The following temperature curves for
various ranges show the heating
characteristics and times for the oven
to reach the selected bake tempera-
ture. Understanding these charac-
teristics can prevent unnecessary
replacement of thermostats, and
solve many customer education type
problems:

MEASURING OVEN TEMPERATURE
It is absolutely necessary to use a
thermocouple type oven tester to
accurately measure oven tem-
perature. No other type of thermom-
eter can take its place.
NOTE: Before testing an oven to
check thermostat calibra-
tion, inspect the thermostat
capillary. It should be pro-
perly mounted in its clips
and should not touch the wall
of the oven liner.
1. Place rack in center position.
Remove all utensils and other
racks.
2. Clip unshielded thermocouple to
center of rack. Run leads out bot-
tom of door at hinge to preserve
top seal.
3. Place oven tester on floor or chair
next to range.
4. Turn oven to “BAKE”, and set con-
trol to 350 degree setting.
5. Allow oven to preheat for 15
minutes.

of the capillary/bulb should be avoid-
ed. If the assembly should be rup-
tured, a simple crimp made by pliers
on each side of the rupture will ade-

CLEAN CIRCUIT
To start a clean cycle the select
switch, thermostat, and timer must be
set for CLEAN, and door must be
latched.
With the select switch set at CLEAN,
the latch solenoid is energized and
allows the latch to be moved to the
clean or latched position - the CLEAN
indicator light also turns “on”. Inthe
latched position the latch operates a
door latch switch and completes the
circuit to energize the broil burner cir-
cuit. {The broil burner heat creates a
“stack” or “flue’ effect to insure vent-
Ing).
When the oven temperature reaches
approx. 550°F the thermal door
switch (located on the flue box) opens
the latch solenoid circuit, and turns
the lock light “on”. At about 650°
oven temperature, thermostat con-
tacts open at COM-NO, and close
COM-NC. This opens the broil burner
circuit and connects the bake burner
circuit.
From a cold start it takes about 45
minutes for the oven to reach clean
temperature (nominal 875°F). The
oven thermostat cycling contacts (1-
2) then cycle the oven bake burner
“off” and “on” to maintain tempera-
ture (approx. 3 min. “on” and 1 min.
“off” - 75% “on time”).

purpose is to connect the bake ther-
mostat circuit for cooking cycles, and
the clean thermostat circuit for clean
cycle. (See Circuit)
The bi-metal coil spring is located on
the bottom of the latch. lt is encased
in a metal case or cover, which is
positioned directly over the oven liner
so it is exposed to the oven heat. The

As the bi-metal coil is heated from
the oven, the coil rotates and turns
the latch arm stop to a point where it
blocks the latch arm and mechani-
cally prevents the ability to unlatch
the door - this “lock-up action oc-
curs at approx. 600° - 6b50°F oven

JGSP10GEK COMPONENTS
The self-clean oven has two burners
— a bake burner and a broil burner,
each with a separate igniter and a
dual section valve.
The components used in self-clean
consist of the following:
® Electronic Control System
— Electronic Control (ERC)
— Relay Circuit Board
— Oven Sensor
e Motorized Door Lock
— Latch
— Motor
— Door Switch
— Anticipator (Heater &
Switch)
— Lock Switches 1 & 2
® Fan - for Control
e Oven Valve
ELECTRONIC CONTROLSYSTEM
The Control System consists of three
(3) components:
1. Electronic Range Control (ERC)
2. Relay Circuit Board
3. Oven Temperature Sensor
The control system components pro-
vide the same functions as a conven-
tional clock, oven select switch, and
the oven temperature control or ther-
mostat.
ELECTRONIC CONTROL (ERC)
The ERC is a solid state smart board
and display which contains user
push-buttons to set the clock, timer,
bake, broil, and self-clean functions.
All temperature functions are con-
trolled by the oven sensor which
plugs into the control.

OVEN SENSOR
The oven temperature is measured
by an oven sensor located in the
upper rear wall of the oven. The sen-
sor increases In resistance as the
temperature increases, which redu-
ces current flow in the sensor circuit.
The ERC monitors the sensor current
and cycles the bake or broil relays on
and off — this in turn turns the oven
on and off.
Page E-21
SELF-CLEAN OVEN
SENSOR RESISTANCE TEST
REMOVE POWER FROM RANGE.
TO TEST AT ERC: Remove 2 wire sen-
sor harness disconnect at right side of
ERC. With oven at room temperature,
check resistance across two sensor
leads (should be approx. 1100 ohms).
If sensor circuit reads open or shorted,
test at oven disconnect to determine if
problem is in sensor or harness.
TO TEST AT OVEN DISCONNECT:
Remove 2 screws holding sensor at
upper right rear oven wall. Gently pull
sensor to expose wire harness dis-
connect. Disconnect sensor and test
sensor resistance (should be approx.
1100 ohms). If sensor checks open or
shorted, replace.
CAUTION: If improperly installed,
sensor disconnect will melt during
self-clean. Do not install against oven
cavity. Be sure to push sensor discon-
nect through cavity and mainback so
that it is visible from rear of range.
RELAY CIRCUIT BOARD
The relay circuit board contains the
step-down transformer which pro-
vides the low-voltage AC needed to
operate the electronic control (ERC). It
also contains the 3 relays which con-
trol bake, broil, and the lock motor and
fan. The relay coils are rated at 25V
DC supplied from the control.

MOTORIZED DOOR LOCK
The door locks automatically when
control is set for clean.
The lock assembly consists of a
motor, latch, 2-lock switches, door
switch, and an anticipator circuit.
The lock motor drives a cam, on top of
the motor, whichs operates the latch
arm and hook. The two (2) lock switch-
es are mounted on top of the motor
and are also operated by the motor
cam.
Page E-24
The door switch is located on the
right side of the motor and is oper-
ated by a spring-loaded activator rod
as the door is opened or closed—the
switch is closed when the door is

The anticipator circuit is used with
the Robertshaw motorized door lock
control system, as the programming
of the Robertshaw control requires
the door lock to cycle to the locked
position and back to the un-locked
position each time power is applied
to the control, regardless of the oven
temperature.
After approximately 5 minutes of a
clean cycle, the “Heat Anticipator”
has generated sufficient heat to open
the ”Bi-Metal Safety Thermostat.”
The cool down process, to close the
Safety Thermostat, can take up to 45
minutes depending on the location of
the Anticipator.
The "Safety Thermostat’ is in series
with the lock motor and provides an
additional safety to prevent the oven
door from unlocking during a clean
cycle. The open Safety Thermostat,
eliminates the possibility of the door
unlocking after a power failure or
momentary power loss.

CLEAN CIRCUIT
For approximately the first 30 min-
utes of the clean cycle the broil relay
is energized by the control which
turns on the broil burner only to start
the clean cycle.
After the first 30 minutes the control
de-energizes the broil relay and ener-
gizes the bake relay which turns on
the bake burner only.
SELF-CLEAN OVEN
The oven sensor tracks the oven
temperature during the clean cycle
and cycles the bake burner (relay)
“on” and “off” to maintain oven
temperature at approx. 875°F.
The fan stays “on” for the entire
clean cycle.

When the Clean Cycle is complete, 3. The lock motor will run until the
and the oven has cooled to approxi-
mately 375 degrees, the ERC re-
moves power from the Lock-Fan relay
coil. The following sequence unlocks
the door and resets all switches in
preparation for the next clean cycle.
1. When the ERC removes power
from the Lock-Fan relay coil, the
relay switch transfers from the
‘NO’ to the ‘NC’ position.
2. As the oven continues to cool, the
anticipator safety thermostat clos-
es. This completes the circuit,
shown below, through the lock

The Hi-Low Microwave Ranges re-
quire a 20-amp receptacle and sup-
ply circuit. A 20 amp receptacle is
supplied with the range and must
be used by the installer to match to
20 amp line cord of the range. (20
amp cords have one vertical terminal
and one horizontal terminal - will not
fit a 15 amp receptacle.)
The reason for the 20 amp circuit is
the microwave oven and the electric
ignition circuits exceed 15 amps
when used at the same time.

Control Functions
The touch control has three func-
tions:
® Cook 1 and Cook 2
Microwave for a preset amount of
time using Power Level 10 or
change power level after setting
time. Cook 1 and Cook 2 allow you
to program 2-stage cooking at two
different power levels.
Page G-2
® Temp Cook
Use the temperature probe to cook
with a preset temperature. You
can program any temperature from
100° to 199°F. Zeros as well as
100 are automatic. For setting a

COOLING FANS
There are two cooling fans used with
the microwave oven:
e Magnetron Fan
e MW Component Fan
The Magnetron Fan is inside the
microwave section directly under the
magnetron.
The Component Fan is located un-
der the microwave section.
Depending on model the component
fan operates as follows:
All Models - Fan is “on” anytime
microwave oven is in use—operated
by microwave oven ‘’on-off’’ switch
(see schematic).
J’ Self-Clean Models - Fan is also
“on” during self-clean cycle when
lock light is “on” —operated by relay
in control panel compartment (see
schematic).

STANDARD TEST LOAD —
POWER TEST
The standard test load is one liter
(1000 ml.) water with a starting
temperature of 59°-75° in a 1000
mi. beaker (WB64X73). (DO NOT USE
ANY OTHER LOAD OR DISH AS
RESULTS WILL VARY FROM STAND-
ARD.)
PERFORMANCE TEST
1. Measure line voltage (loaded). This
test is based on normal voltage
variations of 105V to 130V. Low
voltage will affect power and tem-
perature rise.
2. Place WB64X73 beaker contain-
ing exactly one liter (1000 ml.)
59°-75° water in center of shelf.
Record the starting water temper-
ature with an accurate glass ther-
mometer.
3. Set at HIGH (Power) - set timer
past 2-minute mark.
4. Turnoven “ON” and time for exact-
ly two minutes.
5. At end of two-minute period, re-
cord the water temperature. The
difference between the starting
and ending temperature isthe tem-
perature rise.
Depending on line voltage, the nor-
mal temperature rise should be:
Normal
Line Volts Temperature Rise
120V. 26°F. - 34°F.
(Art Nos. WB 1450, 843)
MICROWAVE SCHEMATICS
Simplified schematics are shown on
following pages. Basic differences
between “H” and “J” models are as
follows: |
“H' Self Clean Models - The micro-
wave oven cannot be used during
the self clean cycle. Line power is
connected to the microwave oven
through the gas oven door latch
switch only when the door is latched.
MICROWAVE
“JJ” Self Clean Models - The micro-
wave oven can be used during the
self clean cycle. A clean relay, con-
nected in parallel with the lock light,
turns on the component fan when
the lock light is energized by the
clean thermostat.

OVEN IGNITION “BOOM NOISE"
(TAPPAN “J” MODELS)
The loud “boom” noise is caused by
delayed ignition of second side of
oven burner on ranges with glowbar
igniter (generally occurs about 10
seconds after oven initially turned
on).
The basic source of the problem and
corrections are listed below:
e Flame cross-over ports in bur-
ner clogged - Can be corrected
by cleaning out grease.
e Burner to valve orifice out of
alignment - Bend/adjust oven
valve mounting to align with
orifice.
e Low gas pressure to oven valve
- Check for obstructions in tubing
- verify gas pressure with man-
ometer at oven orifice and incom-
ing line pressure. Make certain
pressure regulator at correct set-
ting (NAT-LP).

NO IGNITION — BAKE AND
BROIL BURNER
(TAPPAN “J” MODELS)
No ignition problems on models with
glowbar igniters can be caused by
blown 5 amp glowbar fuse due to a
short circuit - problem may be inter-
mittent. Check for:
® Aluminum foil of insulation short-
ing latch switch terminal to
ground.
® Oven select switch terminals
bent and shorted.
® Other glowbar circuit wiring
shorts.
TOP BURNER VALVES —
HARD TO TURN
(TAPPAN “J” MODELS)
Hard-to-turn valves are caused by
defective valve grease, or break-
down of valve grease due to exces-
sive valve temperatures caused by
insulation voids under burner box.
When replacing hard-to-turn valves,
disassemble burner box and add in-
sulation, if necessary, at valve area
and over flue box.
Note: Do not attempt to lubricate
valves - replace only.
TOP BURNER FLAMES
HAVE YELLOW TIPS — LP GAS
(TAPPAN “J MODELS)
Some yellow tip flames on top burn-
ers are normal for LP gas. Thisburner
is designed to provide good perfor-
mance on LP gas and no adjustment
is available.
Page H-2
TOP BURNER YELLOW FLAMES
AND CARBON BUILD-UP
(TAPPAN “J” MODELS)
Yellow flames and carbon build-up
problems with top burners are gen-
erally caused by mis-adjusted burn-
er orifices, low gas pressure, or bad
LP gas mixture.
Orifices - Make certain orifices are
turned all the way down against the
LP needle.
Gas Pressure - Check with manome-
ter at one top burner (with one other
burner “ON”). If pressure is low
(under 10” W.C.) problem is range
regulator or LP gas supply.
TOP BURNER NOISE —
BLOWING & HISSING
(TAPPAN “JJ” MODELS)
Blowing and hissing type noise from
top burners during the first 30-45
seconds of operation is normal for
this burner design. Noise will dimin-
ish after burner heats up (see Gas
Distribution Systems, Section D,
Page D-25).
This condition is normal - Do not
replace burner.
Note: If range is on LP gas and
burner noise persists for long period
of time, check orifice - it may not be
fully seated against LP needle, or
may be too tight and damaged needle.
TOP BURNER FLAME ERRATIC
WITH OVEN IN USE
(TAPPAN “J MODELS)
Erratic top burner flame or outage
during oven use can be caused by
oven flue gasses leaking under cook-
top. Check flue box — it should be
flush with vent openings in back-
guard above cooktop rear edge. If not,
bend to fit or replace flue box.
Note: If burner box very hot, check
for insulation void under burner box.
TOP BURNER VALVES —
ERRATIC “WARM FLAME
(TAPPAN “J” MODELS)
Erratic or no flame at “warm’’ setting
of 225° tri-set top burner valves can
be caused by defective valve grease,
and/or excessive temperatures as
result of insulation voids under burn-
er box.
These conditions cause the valve
core grease to soften, run, and clog
the internal “warm” port in valve.
Do not attempt to repair the valve
-replace only.
TOP BURNER VALVES —
GAS LEAK — WARM ADJ. SCREW
(TAPPAN “JJ” MODELS)
Gas leaks can occur at the “warm”
adjust screw in the shaft of 225” tri-
set valves due to a defective valve.
While the volume of gas is not great,
it can be detected by smell.
Replace any valve that leaks.
FIELD CORRECTIONS
TOP BURNER VALVES —
HI 8: MED FLAME
(TAPPAN “J” MODELS)
The flame size at “HI” and “MED”
settings are about the same size
which sometimes generates custo-
mer complaints.
This is a normal operation of this type
valve and should be considered as
customer education - Do not replace
the valve.
Since there is no detent action at the
“MED” setting, the user can turn the
knob to a slightly lower setting to get
the desired flame size.
GAP AT TOP OF
BLACK GLASS DOOR
(TAPPAN ‘’J’’ MODELS)
There is a 14-inch air gap (space) at
the top of the door glass between the
top edge of the glass and the door
frame.
The gap is part of the door design to
provide an air flow path through the
door. Cooling air enters the door
through slots at the bottom and exits
at the top of the black glass.
The gap is normal and no trim is
missing.
DOOR SPACE NOT SAME
ON BOTH SIDES
(TAPPAN “J” MODELS)
The spacing between the door and
the body side panels should be the
same on both sides as the R.H. and
L.H. hinges are the same.
Page H-3
FIELD CORRECTIONS
If spacing is considerably different
from one side to the other, the hinges
are not to specifications and should
be replaced as a pair. No in-out
hinge adjustment available. (The
door can be adjusted up-down at
each hinge - remove door for access
to adjustment screw).
DOOR HINGE NOISE
(TAPPAN “J”” MODELS)
A broken or missing movable plastic
slider in the hinge assembly will
cause the hinge to ““catch’’ and make
a loud noise when the door is opened
or closed.

To verify, remove the hinge assembly
(3 screws) — and inspect. The inside
end of the hinge arm should be en-
gaged in the slot of a black or dark
gray plastic movable slider. lf the
movable slider is broken or missing,
the metal hinge arm will scrape on
bare metal as the hinge arm moves.
TOP BURNER KNOBS —
HOT OR MELTING
(TAPPAN “J” MODELS)
Top burner knobs on non-self clean
ranges will get extremely hot and
deform (melt) if the door gasket is not
sealing across the top. A large gap
(78-747) between the gasket and the
front frame will cause the problem.
Page H-4
Possible causes are:
e Defective hinges — With door
removed and the hinges set in the
closed position, check for a maxi-
mum 8” space between the top of
hinge arm and front frame. If more
than 8", shim the hinge to rear at
the top screw, or replace the hinge.
e Oven door too high or low — Door
should be positioned so that gasket
fits into opening in front frame.
Adjust door up or down as needed.
Each hinge has an adjustment
screw. Remove door for access to
screws.
e Gasket bind at bottom — Some-
times the door gasket can bind at
the bottom and not allow the top to
close. If door gasket extends across
bottom of door, cut off each side of
gasket about 1%" from bottom of
door. (NOTE - shorter gasket started
production in October 1988.)
® Door insulation voids — Disas-
semble door and check insulation.

HOT COOKTOPS
(TAPPAN “J” MODELS)
Gas range cooktops are normally hot,
especially self clean models during
clean cycle or when broiling.
Possible causes of excessive surface
temperatures are:
® Oven vent alignment — If flue box
IS not positioned properly in back-
guard, oven vent heat will escape
under cooktop. Bend or replace flue
box to correct.
® Insulation voids under burner box
— Disassemble burner box and
check insulation as necessary to fill
any voids.
TOP OVEN TOO HOT
(TAPPAN ‘’J’’ MODELS)
Baking performance problems are
sometimes encountered with breads
and pastries in the top oven of Hi-
Low ranges. The complaints are gen-
erally “burned” or “overcooked” on
bottom of the food.
Possible causes are as follows:
e Black bottom pan being used —
Advise customer to use shiny sur-
face utensils to avoid heat absorp-
tion and over browning.
e Burner flame too hot for small
oven — If range is on natural gas,
try reducing the flame size down to
about % original size by turning
down the burner orifice.
TOP OVEN CORNER SAGS
(TAPPAN “JJ” HI-LOW MODEL)
The right front corner of the top oven
on hi-low ovens wili sag if the top
oven structure is not welded square,
or if the mounting screws are loose
inthe structure angle brackets or ver-
tical support posts.
FIELD CORRECTIONS
If the sag is greater than 4” repair as
follows:
1. Remove top oven sides and rear
panel.
2. Loosen all screws holding struc-
ture to angle brackets and both
vertical support posts.
3. Block up the side of the oven that
IS too low, and retighten all
screws.
4. Remove the support blocking and
check dimensions on both sides.
5. NOTE: In severe cases where the
above steps do not help the prob-
lem, it may be necessary to drill
new holes in the vertical support
post to raise the angle bracket
height on low side.
OVEN PILOT OUTAGE AND
OVEN POPPING NOISE
(TAPPAN “H1' MODELS)
Bowing of the oven back wall may
cause two problems on Tappan “H1"
model 30” and 36” standard ovens.
® Oven pilot outage — bowed back
wall causes “chimney effect’ of air
blowing on pilot as door is opened
or closed.
e Oven popping noise — occurs dur-
Ing baking as oven heats up (oil can
aftect).
Both problems can be corrected by
adding an angle bracket across the
the oven wall — drill 1/16” screw
mounting holes.

(TAPPAN “H” MODELS)
When replacing top burner chrome
bowls because of discoloration (turn-
ing blue) on “H” model ranges, the
following service procedure should
be followed:
1. Check burner types — two differ-
ent types were used:
e Original (Harper-Wyman)

OVEN BURNER WILL NOT
COME ON/PILOT GOES OUT
(ROPER “K” MODELS)
No oven ignition or oven pilot outage
(top burner OK) problems are usu-
ally caused by one of the following:
® Obstruction in oven pilot tubing
— disconnect both ends and blow
through tubing. Also check ends of
tubing for burrs.
® Pilot gas restriction inside ther-
mostat — can sometimes be
cleared by rotating NAT-OFF-LP
pilot select screw several times. If
pilot flame still too small, replace
thermostat.
® Defective oven valve — with ther-
mostat turned “ON”, if elongated
flame envelops sensor normally and
valve does not open, replace valve.
TOP BURNER —
DELAYED IGNITION
(ROPER К’ MODELS)
Delayed ignition of top burners, on
models with spark igniters, can be
caused by mis-alignment of burner
head.
Check burner head position with re-
spect to cooktop. Top of burner head
should be 1/16”-3/16" below cooktop
surface. Bend burner bracket if neces-
sary, to adjust height.

NO GAS FLOW
REGULATOR BACKWARDS
(ROPER “K”” MODELS)
When a new range does not operate
(oven and top burners) inspect the
pressure regulator for proper instal-
lation — it may be backwards.
Check the gas flow arrow on the
pressure regulator body — it should
be pointed towards the range mani-
fold. Another method for identifica-
tion, if the arrow is not visible, is the
location of the regulator vent. It
should be on the range side of the
regulator.
Reinstall the regulator if backwards.
ODOR — DURING OVEN USE
Odors emitting from a new range’s
oven should be considered normal.
Often the odor will be described as a
“burning”, “acid” or “oily” smell
that is more intense when the ovenis
turned on. This condition is more
likely to be noticed when using a new
range that has the self-clean feature
as opposed to a model that has a
standard oven. Self-cleaning ovens
have a heavier blanket of insulation
around the oven. During the produc -
tion procedure, chemical solutions
are used to aid in the installation of
the insulation blanket and oven cav-
ity. The odor caused by this solution
will usually wear off in a very short
time. To speed the process, the con-
sumer may set-up a self-clean cycle
lasting a minimum of 3 hours. The 3
hour self-clean will “break-in” the
oven faster than normal baking rou-
tines.
** These odors are not harmful to any
foodthat happens to be in or onthe
oven!
