Important Safety Information
! WARNING
Read the following information to avoid possible exposure to microwave radiation:
The basic design of the Amana Microwave Oven makes it an inherently safe device to both use and service.
However, there are some precautions which should be followed when servicing the Radarange to maintain this
safety. These are as follows:
1. Always operate the unit from an adequately
grounded outlet. Do not operate on a two-wire
extension cord.
8. Do not for any reason defeat the interlock
switches there is not valid reason for this action
at any time; nor will it be condoned by Amana.
2. Before servicing the unit (if unit is operable) perform
the microwave leakage test.
9. IMPORTANT: Before returning a unit to a
customer, be sure to check for proper switch
interlock action.
3. The oven should never be operated if the door does
not fit properly against the seal, the hinges or hinge
bearings are damaged or broken; the choke is
damaged, (pieces missing, etc.); or any other
visible damage can be noted. Check the choke
area to ensure that this area is clean and free of all
foreign matter.
4. If the oven operates with the door open and
produces microwave energy, take the following
steps:
A. Tell the user not to operate the oven.
B. Contact Maytag Amana Manufacturing
immediately.
5. Always have the oven disconnected when the outer
case is removed except when making the "live"
tests called for in the Service Manual. Do not
reach into the equipment area while the unit is
energized. Make all connections for the test and
check them for tightness before plugging the cord
into the outlet.
6. Always ground the capacitors on the magnetron
filter box with an insulated-handle screwdriver
before working in the high voltage area of the
equipment compartment. Some types of failures
will leave a charge in these capacitors and the
discharge could cause a reflex action which could
make you injure yourself.
10. The Amana Microwave Oven should never be
operated with any components removed and/or
bypassed or when any of the safety interlocks are
found to be defective, or when any of the seal
surfaces are defective, missing, or damaged.
11. All Amana microwave ovens meet all requirements
of the radiation control for Health and Safety Act of
1968. Due to measurement uncertainties, the
maximum leakage for the field will be 4mw/cm2.
12. To ensure that the unit does not emit excessive
microwave leakage and to meet the Department
of Health and Human Services guidelines, check
the oven for microwave leakage using the models
Narda 8110B, Holaday HI-1501, HI-1510, or
HI-1710 leakage monitor as outlined in the
instruction. The maximum leakage level allowed
when following those instructions is 4mw/cm2.
13. If servicer encounters an emission reading over
4mw/cm2, the servicer is to cease repair and
contact the Maytag Service Department
immediately for further direction. Maytag
Manufacturing will contact the proper Government
Agency upon verification of the test results.
7. Always remember that in the area of the
transformer there is HIGH VOLTAGE. When the
unit is operating keep this area clear and free of
anything which could possibly cause an arc or
ground, etc.

sure these grounding instructions are followed.
! WARNING
Do not remove grounding prong when installing
grounded appliance in a home or business that does
not have three wire grounding receptacle, under no
condition is grounding prong to be cut off or removed.
It is the personal responsibility of the consumer to
contact a qualified electrician and have properly
grounded three prong wall receptacle installed in
accordance with appropriate electrical codes.
! WARNING
To avoid the risk of electrical shock or death, do not
alter the plug.
! WARNING
To avoid the risk of electrical shock or death, this
equipment must be grounded.
This equipment MUST be grounded. In the event of an
electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the
electric current. This oven is equipped with a cord
having a grounding wire with a grounding plug. The plug
must be plugged into an outlet that is properly installed
and grounded.
Consult a qualified electrician or servicer if grounding
instructions are not completely understood, or if doubt
exists as to whether the equipment is properly
grounded.
Do not use an extension cord. If the product power cord
is too short, have a qualified electrician install a threeslot receptacle. This oven should be plugged into a
separate 60 hertz circuit with the electrical rating as
shown in the appropriate drawing. Models operate with a
120 supply voltage. When a microwave oven is on a
circuit with other equipment, an increase in cooking
times may be required and fuses can be blown.

Important Safety Information
Servicing of Grounded Products
Explanation
The standard accepted color coding for grounding wires
is GREEN or GREEN WITH YELLOW STRIPE. These
ground leads are NOT to be used as current carrying
conductors. It is extremely important that the technician
replace any and all grounds prior to completion of the
service call. Under no condition should ground wire be
left off causing a potential hazard to technicians and
consumer.
Polarization–This means that the larger slot must be
neutral and the small slot must be hot (live).
Mispolarized–The outlet is miswired so that the larger slot
is hot (live) and the smaller slot is neutral.
Grounded–This means the round hole connection is
connected to earth ground through a connection to the main
power panel.
Ungrounded–The round hole connection is not complete
to earth ground and/or the main power panel.
Wiring
A good service practice is never route wiring over
terminals and/ or sharp edges. This applies to any wiring
without regard to the circuit voltage. Wire installation
material and thickness is designed and regulated for
electrical spacing purpose only, but cannot always be
relied upon because of possible cuts and/or abrasions,
which can occur during servicing.
!
WARNING
To avoid risk of electrical shock, personal injury or
death; verify the oven is properly grounded and
polarized.
Test Procedures (2 Methods)
Method #1
Purchase and use a ground monitor which indicates a
correctly or incorrectly wired outlet by instructions
imprinted on the monitor body.
Method #2
Voltmeter - (Use scale over 125 Volts A.C.)
• Test A - "H" to "N" must indicate line voltage.
• Test B - "H" to "G" must indicate line voltage.
• Test C - "N" to "G" must indicate zero (0) volts.
If "N" to "G" indicates line voltage the outlet is improperly
polarized.
Proper Grounding and Polarization of
120 Volts Wall Outlets
For the safety of our customers and the service
technician ALL appliances have a three–prong power
cord and MUST be connected to a properly polarized and
grounded wall outlet.
If "H" to "G" indicates zero (0) volts the outlet is not
grounded.
This information was written for those who do not
understand grounding and polarization of a wall outlet.
A 120 volt wall outlet must always be wired as shown
below.
Neutral (N) - This slot is
the larger of the two and
should be neutral (dead)
with respect to ground.
Hot (H) - This slot is
the smaller size and
should always be hot
(live) with respect to
neutral (N) and ground(G).
H
N
!
CAUTION
To avoid risk of electrical shock, personal injury or
property damage; wiring changes or grounding of wall
outlet are to be made only by a qualified electrician.
G
Ground (G) - The round hole connection
is for the grounding circuit. Behind the
cover plate a green wire should be
connected to this terminal.

General Test Information
Most testing in the manual is conducted with an
ohmmeter using a multiplier scale of X 10k (k–thousand
ohms). When using this scale, it is important that your
fingers do not touch the metal parts of the test probes.
To do so will give a false indication of the ohm reading.

Microwave Power Test Procedures
!
WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
Power Test (Traditional 1 Liter Test)
Test equipment required is Amana power test kit R0157397 (Fahrenheit), or Menumaster power test kit M95D5
(Celsius).
1. Fill the plastic container to the bottom of the 1000 ml. line with cool tap water.
2. Using the thermometer; Fahrenheit or Celsius, stir the water, measure and record the water temperature.
Initial water temperature should be approximately 60°F.
3. Place container on the center of the oven shelf and heat the water for 63 seconds.
NOTE:
Use a watch second hand, not the oven timer.
4. Stir the water, measure and record the temperature of the water after heating time is complete.
5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the
temperature rise.
6. See the Temperature Chart provided below.
NOTE: Always perform power test three times for accuracy, changing the water after each test is performed.
NOTE:
Variation or errors in the test procedure will cause a variance in the temperature rise indication. Additional
power tests should be made if temperature rise appears marginal.
NOTE:
Low line voltage may cause lower power output (temperature rise).

Microwave Leakage Testing Procedures
!
WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
!
WARNING
Check for radiation leakage after servicing. Should
the leakage be more than 4mW/cm2 inform Maytag
immediately. After repairing or replacing any
radiation safety device, keep a written record for
future reference, as required by D.H.H.S. and
HEW regulations. This requirement must be strictly
observed. In addition, the leakage reading must be
recorded on the service repair ticket while in the
customer’s home.
Equipment
•
•
•
•
•
•
•
DANGER
Whenever you replace the magnetron, measure for
radiation leakage before the outer panel is installed
and after all necessary components are replaced or
adjusted. Special care should be taken in measuring
around the magnetron.
After all components including the outer panel are fully
assembled, measure for radiation leakage around the
door periphery, the door viewing window, the exhaust
opening, and air inlet openings.
Note before measuring -
•
!
Avoid contacting any high voltage components.
Measurement With a Fully Assembled
Oven
Electromagnetic radiation monitor
600 cc glass beaker
Procedure For Measuring Radiation
Leakage
•
Measurement With the Outer Panel
Removed
Do not exceed meter full scale deflection. Leak
monitor should initially be set to the highest scale.
To prevent false readings the test probe should
be held by the grip portion of the handle only.
The scan speed is equal to one inch per antenna
revolution or one inch per second if antenna speed
is unknown.
Areas to be checked are all door seal areas and
any venting parts.
Leakage with the outer panel removed
...4mW/cm2 or less.
Leakage for fully assembled oven with door
normally closed ...4mW/cm2 or less.
Leakage for a fully assembly oven (before the
latch switch (primary) is interrupted) while pulling
the door ... 4mW/cm2 or less.
Record Keeping and Notification After
Measurement
1. After any adjustment or repair to a microwave
oven, a leakage reading must be taken. Record
this leakage reading on the repair ticket even if it
is zero.
2. A copy of the repair ticket and the microwave
leakage reading should be kept by the repair
facility.
1. Pour 275 cc ±15 cc (9 oz ±1/2 oz) of 20°C ± 5°C
(68°F ± 9°F) water in a beaker which is graduated
to 600 cc and place the beaker in the center of
oven.
2. Set the radiation monitor to 2450 MHz and use it
following the manufacturer’s recommended test
procedure to assure correct results.
3. While measuring the leakage, always use the two
inch (5 cm) spacer supplied with the probe.
4. Press the start pad or turn on the timer and with
the magnetron oscillating, measure the leakage
by holding the probe perpendicular to the surface
being measured.

Cooking Guidelines
The Amana Microwave Oven can make your job easier.
You’ll cook ahead and pre-portion more. You’ll also spend
less time preparing special-order dishes.
To be sure of consistently good results, remember a few
simple guidelines.
How Microwave Ovens Heat Food
All food and liquid molecules have positive and negative
particles which are in constant, but slow, motion.
(Positive and negatives attract and repel each other like
magnets.) In microwave cooking this molecular action is
then accelerated. The instant microwaves bombard food
which agitate the molecules. Agitation causes friction as
molecules rub and bump into each other at an increased
rate. Friction results in heat that cooks food and boils
water.
Once the microwaves stop, this friction action continues
by itself, eventually tapering off and returning to normal
molecular action.
Microwaves penetrate food to a depth of ¾" to 1½". As
cooking begins, heat is spread by conduction to the
interior portion of the food just as in conventional cooking
methods.
Food Variables
Microwave cooking can be directly affected by different
food variables.
The shape of foods can greatly affect the amount of
cooking time. Foods that are flat and thin heat faster than
foods which are chunky. For example, a casserole will
cook faster in a flat dish, rather than if heaped in a small
dish. Foods cut into small pieces will cook faster than
large-shaped foods. Pieces should be of a uniform size
and shape for more uniform cooking, or the smaller
pieces will cook faster. The greatest amount of heating
takes place within ¾" of the food’s surface. The interior of
large food items, or dense foods, is heated by the heat
conducted from the outer food layer. The most uniform
heating occurs in flat, doughnut-shaped foods. For best
results, cook foods together which have similar sizes and
shapes.
The quantity or volume of a food can affect the amount of
cooking time. As the volume of the food is increased, the
time required to cook or heat the item increases almost
proportionately. If twice the amount of food is placed in
the oven, it will take almost twice as long to cook. To
determine the time for larger quantities, multiply the
individual serving time by the increased amount, then
reduce the total heating time by about 20%.
©2004 Maytag Appliances Company
The density of foods can greatly affect the amount of
cooking time. Porous foods, such as breads, cakes or
pastries, will heat much more quickly than dense meats
of the same size. Porous foods absorb microwaves
quickly throughout. Meats absorb microwaves mostly at
the exterior surface, and the interior is heated by
conduction, increasing the cooking time. Meats can be
cooked in a sauce, if desired. Due to the moisture
content, a sauce will heat rapidly. The heat will transfer to
the meat, so the meat will heat faster due to heat by
conduction as well as by microwaves.
The starting temperature of foods affects the amount of
cooking time. Each temperature degree that the food
item is to raise must be supplied with a definite amount
of energy. Lower initial starting temperatures require more
energy and more time to cook. Therefore, refrigerator
temperature foods require a longer cooking time than
room temperature foods. Foods already slightly warm will
heat very quickly in the oven.
The moisture content of foods affects the amount of
cooking time. The higher the moisture content is in a
food the longer the amount of cooking time.
The fat and sugar content of foods affects the amount
of cooking time. Foods containing high fat and sugar
levels heat very quickly and may reach much higher
temperatures than foods having low fat and sugar levels.
Foods having lower fat and sugar levels require longer
cooking times.
The arrangement of food within a microwave oven cavity
affects the way in which the food cooks. A “round”
arrangement is best. Use round utensils whenever
possible. Also, arrange foods such as baked potatoes in
a circle, rather than in rows, for cooking. When only one
food item is being cooked, place it in the center of the
oven glass shelf for cooking.
Manipulation of Foods
Sometimes recipes suggest manipulating or moving food
during cooking. There are several forms of manipulation:
Stirring is required less often in microwave cooking than
in conventional cooking. In conventional cooking, you use
a spoon to move food up from the bottom of a pan to
evenly distribute the heat. In microwave cooking, you still
stir to redistribute the heat within some foods, but you
need to stir from the outside of a dish toward the inside
or center. If a recipe states to stir once or twice during
cooking, stir at approximately even intervals. For
example, in a 12-minute cooking period, if a recipe states
to stir twice, stir after 4 minutes of cooking and again,
after 8 minutes of cooking. However, it is not necessary
to be precise. Stir only when necessary. When using
lower power levels or settings, less stirring is required.
Some examples of foods which may require stirring are
puddings, some casseroles, some sauces, some soups,
and some egg dishes. Some foods can’t be stirred.
These foods are rearranged or turned.
16023053 Rev. 0
A–7
Cooking Guidelines
Some foods can’t be stirred and should be repositioned
or rearranged during cooking. Some examples include
baked potatoes, cupcakes (in custard cups), and
chicken pieces. Rearranging allows for more even
cooking of foods. Foods which are cooked, covered or
which are cooked using lower power levels, usually
require little rearranging.
There are actually two types of turning. Turning is done
when foods cannot be stirred. Foods which are cooked,
covered or which are cooked at lower power levels
usually require little turning.
Turning foods over: Turning foods over is done to
distribute heat. Meat and poultry are two types of foods
which are sometimes “turned over.” Examples include
roasts, turkeys and whole chickens. Small meat items
such as poultry pieces may need to be turned over when
in casseroles, or when in a browning skillet.
Microwave Utensils
! CAUTION
To avoid burns, use protective gloves or pads when
removing dishes from oven. Some utensils become
hot while cooking.
Never use cooking containers or covers with any metal
content. This includes all metal and enameled metal-core
ware, foil, and metal-trimmed containers. Suitable
heating containers include those made of paper products,
glass, china, cloth, and wicker baskets.
Recommended
Glass/ceramic
Natural fiber cloth
Non-recycled paper
Plastic
Wood
A–8
Not Recommended
Aluminum foil
Grocery bags
Recycled paper
Lead crystal
Newspapers
Metal
Metallic trimmed china
Utensil Check Test
Use the following test to check utensils for microwave
safeness.
1. Place glass measuring cup of water next to
empty dish to be tested in microwave oven.
2. Heat on full power for one minute.
3. Check temperature of dish and water.
• If dish remains cool and water is hot, dish is
microwave safe.
• If dish is slightly warm, use for short term cooking.
• If dish is hot and water is cool, do not use. Dish
remains cool if not absorbing microwaves and
microwaves are being absorbed by water. Dish
becomes hot if absorbing microwaves.
Cooking Hints
Cover foods for faster, more even heating. Glass
lids, plastic wrap, plate covers or other paper products
may be used. Do not seal. Instead, allow for steamventing at all times.
Pierce pouches, plastic wrap covers and all foods
with a thin skin or membrane, such as potatoes, squash,
tomatoes, eggs, etc. This prevents an eruption in the
oven and allows for expansion and/or the escape of
steam.
Foods should be carefully arranged. For best results,
arrange food such as vegetables or casserole-type items
evenly around the edge of the plate with slightly less
depth in the center. The edges of food items should not
overlap or overhang the rim of the container. Cover meats
with gravy or au jus and moisten all dry foods other than
bread or pastry items.
Do not stack food or plated dishes in your oven.
Instead, when heating more than one serving or platters,
all plates should be placed at the same level in the oven,
with space between all containers.

reduce the total heating time by about 20%.

The density of foods can greatly affect the amount of
cooking time. Porous foods, such as breads, cakes or
pastries, will heat much more quickly than dense meats
of the same size. Porous foods absorb microwaves
quickly throughout. Meats absorb microwaves mostly at
the exterior surface, and the interior is heated by
conduction, increasing the cooking time. Meats can be
cooked in a sauce, if desired. Due to the moisture
content, a sauce will heat rapidly. The heat will transfer to
the meat, so the meat will heat faster due to heat by
conduction as well as by microwaves.
The starting temperature of foods affects the amount of
cooking time. Each temperature degree that the food
item is to raise must be supplied with a definite amount
of energy. Lower initial starting temperatures require more
energy and more time to cook. Therefore, refrigerator
temperature foods require a longer cooking time than
room temperature foods. Foods already slightly warm will
heat very quickly in the oven.
The moisture content of foods affects the amount of
cooking time. The higher the moisture content is in a
food the longer the amount of cooking time.
The fat and sugar content of foods affects the amount
of cooking time. Foods containing high fat and sugar
levels heat very quickly and may reach much higher
temperatures than foods having low fat and sugar levels.
Foods having lower fat and sugar levels require longer
cooking times.
The arrangement of food within a microwave oven cavity
affects the way in which the food cooks. A “round”
arrangement is best. Use round utensils whenever
possible. Also, arrange foods such as baked potatoes in
a circle, rather than in rows, for cooking. When only one
food item is being cooked, place it in the center of the
oven glass shelf for cooking.
Manipulation of Foods
Sometimes recipes suggest manipulating or moving food
during cooking. There are several forms of manipulation:
Stirring is required less often in microwave cooking than
in conventional cooking. In conventional cooking, you use
a spoon to move food up from the bottom of a pan to
evenly distribute the heat. In microwave cooking, you still
stir to redistribute the heat within some foods, but you
need to stir from the outside of a dish toward the inside
or center. If a recipe states to stir once or twice during
cooking, stir at approximately even intervals. For
example, in a 12-minute cooking period, if a recipe states
to stir twice, stir after 4 minutes of cooking and again,
after 8 minutes of cooking. However, it is not necessary
to be precise. Stir only when necessary. When using
lower power levels or settings, less stirring is required.
Some examples of foods which may require stirring are
puddings, some casseroles, some sauces, some soups,
and some egg dishes. Some foods can’t be stirred.
These foods are rearranged or turned.

Cooking Guidelines
Some foods can’t be stirred and should be repositioned
or rearranged during cooking. Some examples include
baked potatoes, cupcakes (in custard cups), and
chicken pieces. Rearranging allows for more even
cooking of foods. Foods which are cooked, covered or
which are cooked using lower power levels, usually
require little rearranging.
There are actually two types of turning. Turning is done
when foods cannot be stirred. Foods which are cooked,
covered or which are cooked at lower power levels
usually require little turning.
Turning foods over: Turning foods over is done to
distribute heat. Meat and poultry are two types of foods
which are sometimes “turned over.” Examples include
roasts, turkeys and whole chickens. Small meat items
such as poultry pieces may need to be turned over when
in casseroles, or when in a browning skillet.
Microwave Utensils
! CAUTION
To avoid burns, use protective gloves or pads when
removing dishes from oven. Some utensils become
hot while cooking.
Never use cooking containers or covers with any metal
content. This includes all metal and enameled metal-core
ware, foil, and metal-trimmed containers. Suitable
heating containers include those made of paper products,
glass, china, cloth, and wicker baskets.

Utensil Check Test
Use the following test to check utensils for microwave
safeness.
1. Place glass measuring cup of water next to
empty dish to be tested in microwave oven.
2. Heat on full power for one minute.
3. Check temperature of dish and water.
• If dish remains cool and water is hot, dish is
microwave safe.
• If dish is slightly warm, use for short term cooking.
• If dish is hot and water is cool, do not use. Dish
remains cool if not absorbing microwaves and
microwaves are being absorbed by water. Dish
becomes hot if absorbing microwaves.
Cooking Hints
Cover foods for faster, more even heating. Glass
lids, plastic wrap, plate covers or other paper products
may be used. Do not seal. Instead, allow for
steamventing at all times.
Pierce pouches, plastic wrap covers and all foods
with a thin skin or membrane, such as potatoes, squash,
tomatoes, eggs, etc. This prevents an eruption in the
oven and allows for expansion and/or the escape of
steam.
Foods should be carefully arranged. For best results,
arrange food such as vegetables or casserole-type items
evenly around the edge of the plate with slightly less
depth in the center. The edges of food items should not
overlap or overhang the rim of the container. Cover meats
with gravy or au jus and moisten all dry foods other than
bread or pastry items.
Do not stack food or plated dishes in your oven.
Instead, when heating more than one serving or platters,
all plates should be placed at the same level in the oven,
with space between all containers.
