Important Safety Information
!
CAUTION
Read the following information to avoid possible exposure to microwave radiation:
The basic design of the Maytag and 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 microwave oven 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.
2. Before servicing the unit (if unit is operable), perform
the microwave leakage test.
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 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 and H. V. Capacitor 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.
4
7. In the area of the transformer, capacitor, diode, and
magnetron there is HIGH VOLTAGE. When the unit is
operating, keep this area clean and free of anything
which could possibly cause an arc or ground, etc.
8. Do not for any reason defeat the interlock switches.
There is no valid reason for this action at any time;
nor will it be condoned by Maytag.
9. IMPORTANT: Before returning a microwave to a
customer, check for proper switch interlock action.
The primary and secondary switches MUST open
when the door is actuated. The monitor switch MUST
close at a 1/4 inch when the door is opened.
10.Before returning a microwave to a customer, verify
the door spacing is reasonably uniform along the
top, bottom, and sides, and that it measures 1/8 inch
or less.
11. The microwave oven should never be operated with:
• Any components removed and/or bypassed.
• Any of the safety interlocks failing.
• Any of the seal surfaces failing, missing, or
damaged.
12.To ensure that the unit does not emit excessive
microwave leakage and to meet the Department of
Health Human Service guidelines, check the oven
for microwave leakage using Narda Model 8100,
8200, Holaday HI1500, HI1501 or Simpson 380M
leakage monitor as outlined in the instructions. The
maximum leakage level allowed is 4mW/cm2.
13. If servicer encounters an emission reading over
4 mW/cm2 the servicer is to cease repair and contact
the Maytag Service Department immediately for
further direction. Maytag will contact the proper
Government Agency upon verification of the test
results.

Microwave Leakage Testing
!
Measurement With the Outer Panel
Removed
W ARNING
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.
Avoid contacting any high voltage components.
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.
Equipment
Measurement With a Fully Assembled Oven
• Electromagnetic radiation monitor
• 600 cc glass beaker
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.
Procedure For Measuring Radiation
Leakage
Note before measuring • 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 assembed oven (before the latch
switch (primary) is interrupted) while pulling the door ...
4mW/cm2 or less.
1 . Pour 275 ±15 cc (9 oz ±1/2 oz) of 20 ± 5°C
(68 ± 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.
©2004 Maytag Services
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.

General Information
Electrical Requirements
Grounding Instructions
The oven is designed to operate on a Standard 120 VAC,
60 HZ household outlet.
This appliance must be grounded. If an electrical short
circuit occurs, grounding reduces the risk of electric
shock by providing an escape wire for the electric current.
The cord for this appliance has a grounding wire with a
grounding plug. Put the plug into an outlet that is properly
installed and grounded.
Cleaning
Before cleaning the oven, unplug the power supply cord. If
impossible, open the oven door to prevent an accidental
oven start.
Inside of the Oven
Use a damp cloth to wipe out crumbs and spillovers. It is
important to keep the area between door and cavity front
clean to assure a tight seal. Remove greasy spatters with
a sudsy cloth, then rinse and dry. Do not use harsh
detergent or abrasive cleaners.
Glass Tray
The glass tray can be washed by hand or in the
dishwasher.
!
Ask a qualified electrician if you do not understand the
grounding instructions or if you wonder whether the
appliance is properly grounded.
Keep the electrical power cord dry and do not pinch or
crush it in any way.
Control Panel
Wipe with a damp cloth followed immediately by a dry
cloth. The Child Lock feature is also useful when cleaning
the control panel. Child Lock prevents accidental
programming when wiping the control panel
(if so equipped).
Properly Polarized and
Grounded Outlet
Door
If steam accumulates inside or around the outside of the
oven door, wipe the panel with a soft cloth. This may
occur when the microwave oven is operated under high
humidity conditions and in no way indicates a malfunction
of the unit.
Outside Oven Surface
Clean with damp cloth. To prevent damage to the
operating parts inside the oven, the water should not be
allowed to seep into the ventilation openings.
After cleaning the oven, be sure that the rotating ring and
the glass tray are in the right position. Press the STOP/
CLEAR pad twice to reset any accidental key setting.

Installation Instructions
READ CAREFULLY. KEEP THESE INSTRUCTIONS.
IMPORTANT SAFETY INSTRUCTIONS
WARNING
Before attempting the installation of this kit, be sure to unplug the oven from wall receptacle.
Your oven is designed to be installed under properly constructed, good condition wood or metal cabinets that are sturdy enough to support
the items you have in the cabinet, plus an additional 41 kg (90 pounds) from the cabinet bottom.
Empty the contents of your selected cabinet and the delicate items in adjoining cabinets.
(NOTE: When drilling the holes, the vibration could cause damage to fragile items such as crystal or china.)
Now, you must inspect your cabinets. If any of the following conditions exist, then it is your personal responsibility to test the cabinets or
contact a qualified cabinet maker.
1. Separation of joints between the bottom shelf and the cabinet structure.
2. Splitting, cracking or other signs of deterioration.
3. Check the number of screws used to install your cabinets. If your cabinet is attached to the wall with only two screws at the top, then
you must add two screws at the bottom to firmly secure your cabinet to the wall. When adding the screws, be sure that they enter wall
studs with at least 1.3 cm (1/2”) penetration.
4. On wood cabinets, the bottom shelf must be at least .48 cm (3/16”) thick masonite or plywood.
5. Be sure that the underside of the cabinet is at least 50 cm (20”) wide and 35.0cm (13 25/32”) deep. If the cabinet is less than
35.0cm(13 25/32”) deep, follow the cabinet mounting instructions catefully if you desire to mount your oven under cabinet.
To test your cabinets, place a 40 KG(90LB.) load, plus the equivalent weight of items normally stored on the shelf*, for a minimum of five
minutes.
*You may consider using jugs of water, bricks or books to obtain the test load.
PLEASE NOTE: If your cabinet is properly constructed and suitably installed it will withstand this test without any damage; however, there
is the possibility of damage should the cabinet be incapable of supporting the additional load.
The Maytag Company is NOT RESPONSIBLE FOR ANY DAMAGE OR OTHER CONSEQUENCES resulting from the performance of
this test.
If you are unsure that your cabinets are suitable for this type of installation you may use the oven on your countertop.

TWO MOUNTING METHODS
There are two mounting methods described in this booklet that can be used.
1. Countertop Method
You can use this method if you decide not to cabinet mount your oven.
To use your oven as a countertop model, simply position the oven on the desired counter and plug the electrical cord into a three
prong (grounded)wall receptacle.
2. Cabinet Mounting Method
This method is for mounting your oven under a cabinet and uses the template, 4-washers and one set of screws. Before using this method,
the 4 plastic plug buttons on the top of the oven must be removed. This can be done by placing a thin flat blade screwdriver between the
plug button and the oven top and raising gently, taking care to avoid acratching the oven top.
OVEN MAY BE MOUNTED TO CABINETS WITH OR WITHOUT A FRONT RAIL.

DRILLING APPROACH
You have two options for drilling the mounting holes for your oven.
First, you can drill from inside of the cabinet if you have adequate space and your shelves are removable.
Second, you can drill from the bottom.
If possible, it is generally easier to work from the inside of the cabinet. Use the instructions applicable to the approach you select. Make
sure you use the template properly depending whether you drill holes from the inside or bottom side of the cabinet.
INSTRUCTIONS FOR DRILLING FROM INSIDE
If you cannot drill from the inside, go to Instructions for Drilling From Bottom.
1. If your cabinet is less than 35cm(13 25/32”) deep, cut off the front edge of Template 2 the amount by which the cabinet depth is less
than 35cm(13 25/32”), using the template cut lines as a fuide. Place Template2 inside cabinet. Cut around door jam and if necessary,
corners to make template fit.(The front edge of template must be even with the front edge of the cabinet.) Place Template 2 in
cabinet.
NOTE: For cabinets with a recessed shelf you must measure the thickness of the front rail and cut that amount off the front edge of
Template 2 using the template cut lines as a guide. This will allow Template 2 to lay flat in the shelf.
2. If you have a partition in the cabinet, you must do the following:
• Cut Template 2 into two pieces to fit each side of the partition.
• Position one piece of Template 2 inside the cabinet, making sure that the front edge is even with the front edge of cabinet.
• Position Template 1 on front of the cabinet so that the arrow is aligned with the hole center line on Template 2.
• Position remaining piece of Template 2 inside cabinet and align the hole center lines with arrows on Template 1 so that
distance from right hole center to left hole center measures the distance indicated on the template. (You will have to cut
excess paper from the middle of Template 2 to make it lay flat.)
• Position the remaining piece of Template 2 inside cabinet.
• Check again to make sure that the hole center lines on Template 2 are straight and that the distance from the right to left
drilling holes measures the distance indicated on the template.
• Go to Drilling the Mounting Holes.
INSTRUCTIONS FOR DRILLING FROM BOTTOM
1. If you have a front rail, measure the thickness and cut that amount off the front edge of Template 2 using the template cut lines as a
guide.
2. Place cut edge of Template 2 against the back side of the front rail and position it flat against the bottom side of the cabinet.
NOTE: On some cabinets a small bracket or glue block is used between the overhang and the underside of the cabinet bottom. If this is
true of your cabinets, cut Template 2 to fit around the bracket or glue block so that it will be flat on the cabinet bottom when attached.
3. If you have a partition you must do the following:
• Cut Template 2 into two pieces to fit on each side of the partition.
• Position one piece of Template 2 under the cabinet. (The cut line along the front edge of Template 2 must be placed
against the back of the front rail.)
• Attach Template 1 to rear of cabinet and align arrows with hole center line on Template 2.
A–8
16022923 Rev. 0
©2004 Maytag Services
• Position remaining piece of Template 2 under the cabinet and align the hole center lines with arrows on Template 1 so
that the distance from right hole center to left hole center measures the distance indicated on the templates. (You may
have to cut excess paper from middle of the template to make it lay flat.)
• Position Template 2. (The cut line along the front edge of template must be placed against the back of the front rail.)
DRILLING THE MOUNTING HOLES
While drilling, it is recommended that safety glasses be worn to prevent possible eye damage from cabinet shavings.
1. Use a center punch or nail to make an indentation for centering the drill bit.
2. Drill through Template 2 at the four black drilling holes indicated on the template. (Drill should be held straight to ensure proper
alignment of bolts.)
3. After drilling the four holes, remove the template and clean the drill holes.
SELECTING YOUR MOUNTING BOLTS
1. You should have three sets of bolts of varying lengths in the installation package. select one bolt of each size.
2. Hold each bolt against the cabinet front rail. pick the bolt that extends beyond top of the bottom shelf by. 48 cm (3/6") to 2.54 cm (1").
this will be the bolt length needed for your cabinets.
2.54cm~0.5cm
(1"~3/16")
TOP OF BOTTOM SHELF
NOTE: It is important to pick the correct bolt length needed for your cabinets. If the bolt is too short it won't reach the oven. If the bolt is
too long, it will not permit oven to be drawn up to the cabinet snugly.
3. From inside the cabinet, insert the bolts through the mounting straps and then into the drilled holes.
MOUNTING THE OVEN
To aid installation, we suggest that you use some solid support such as books to hold the oven while you are securing it with the mounting
bolts.
Make sure that whatever you use is stacked or cut as close as possible to the height needed for the oven to reach the cabinet bottom.
1. Place the oven on the support and move into position. Lift oven, aligning the mounting holes on the oven with the bolts. Do not grip
the door handle to help lift the oven.
2. Insert bolts into mounting holes on the oven. Tighten the bolts to secure oven to the bottom of the cabinet.(Alternate between bolts so
that oven is drawn up evenly.)
3. Once oven is securely in place, plug power cord into three prong (grounded) wall receptacle.

Care and Cleaning
All Models
Care and Cleaning
Follow these instructions to clean and care for your oven.
• Keep the inside of the oven clean. Food particles and
spilled liquids can stick to the oven walls, causing the
oven to work less efficiently.
• Wipe up spills immediately. Ue a damp cloth and mild
soap. Do not use harsh detergents or abrasives.
• To help loosen baked on food particles or liquids, heat
two cups of water (add the juice of one lemon if you
desire to keep the oven fresh) in a four-cup measuring
glass at High power for five munutes or until boiling.
Let stand in the oven for one or two minutes.
• Remove the glass tray from the oven when cleaning
the oven or tray. To prevent the tray from breaking,
handle it carefully and do not put it in water
immediately after cooking. Wash the tray carefully in
warm sudsy water or in the dishwasher.
• Clean the outside surface of the oven with soap and a
damp clith. Dry with a soft cloth. To prevent damage
to the operatin parts of the oven, don’t let water seep
into the openings.
• Wash the door window with very mild soap and water.
Be sure to use a soft cloth to avoid scratching.
• If steam accumulates inside or outside the oven door,
wipe with a soft cloth. Steam can accumulate when
operating the oven in high humidity and in no way
indicates microwave leakage.
• Never operate the oven without food in it; this can
damage the magnetron tube or glass tray. You may
wish to leave a cup of water in the oven when it is not
in use to prevent damage if the oven is accidentally
turned on.
