Read the following information to avoid possible
exposure to microwave radiation:
The basic design of the Amana and Menumaster
microwave ovens make it an inherently safe device to
both user and servicer. 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 earthed
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 this 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 earth 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.
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 earthing, 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 actuate
when the door is opened. The monitor switch MUST
close at a
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
/64–inch (0.5 mm) or less.
11. The Amana or Menumaster microwave oven should
never be operated with:
• Any components removed and/or bypassed.
• Any of the safety interlocks found to be
defective.
• Any of the seal surfaces defective, 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 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.
Precautions to be observed before and during
servicing to avoid possible exposure to excessive
microwave energy, or electrical shock, disconnect
power to oven.
(A) Do not operate or allow oven to be operated with
door open.
(B) Make the following safety checks on all ovens to
be serviced before activating the magnetron or
other microwave source, and make repairs as
necessary:
• Interlock operation
• Proper door closing
• Seal and sealing surfaces (arcing, wear, and
other damage)
• Damage to or loosening of hinges and latches
• Evidence of dropping or abuse
(C) Before turning on microwave power for any service
test or inspection within the microwave generating
compartments, check the magnetron, waveguide or
transmission line, and cavity for proper alignment,
integrity, and connections.
(D) Any defective or misadjusted components in the
interlock, monitor, door seal, and microwave
generation and transmission systems shall be
repaired, replaced or adjusted by procedures
described in this manual before oven is released to
the consumer.
(E) Check microwave leakage to verify compliance with
the federal performance standard. This should be
performed on each oven prior to release to the
consumer.
Wiring
Good service practice is to never route wiring over
terminals and/or sharp edges. This applies to any wiring
without regard to the circuit voltage. Wire insulation
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, make sure these earthing instructions are
followed.
Earthing Instructions
!
WARNING
Do not remove earthing prong when installing earthed
appliance in a home or business that does not have
three wire earthing receptacle, under no condition is
earthing prong to be cut off or removed. It is the
personal responsibility of the consumer to contact a
qualified electrician and have properly earthed three
prong wall receptacle installed in accordance with
appropriate electrical codes
Should a two prong adapter plug be required temporarily,
it is the personal responsibility of the consumer to have it
replaced with properly earthed three prong receptacle or
the two prong adapter properly earthed by a qualified
electrician in accordance with appropriate electrical
codes.
Servicing of Earthed Products
The standard accepted color coding for earthing wires is
GREEN or GREEN WITH YELLOW STRIPE. These
earth leads are NOT to be used as current carrying
conductors. It is extremely important that the technician
replace any and all earths prior to completion of the
service call. Under no condition should earth wire be left
off causing a potential hazard to technicians and
consumer.
• Inspect equipment for damage such as dents in door
or dents inside oven cavity.
• Report any dents or breakage to source of purchase
immediately. Do not attempt to use oven if damaged.
• Remove all materials from oven interior.
Equipment Placement
• Do not install equipment next to or above source of
heat, such as pizza oven or deep fat fryer. This could
cause microwave oven to operate improperly and
could shorten life of electrical parts.
• Do not block or obstruct air filter. Allow access for
cleaning.
• Install on level countertop surface.

Proper Handling of Magnetron Tubes
CAUTION
!
A magnetron tube, like a radio or television tube
must be handled with a reasonable amount of care.
When handling a tube, always handle by the housing
only. Use caution not to touch or strike the ceramic
portion at the top. The carton used to ship service
replacement tubes is reusable.
Magnetron Failure Modes
Magnetron failures that have been identified are
generally grouped into categories shown below.
1. Shorted
Air - This is a case where the tube has had the vacuum
envelope destroyed and air has entered the tube.
This will cause internal arcing and high secondary
current if high voltage is applied.
R.F. Capacitors - May short to chassis. This condition
will also cause loss of high voltage.
WARNING
2. Open Heater (Filament) - Can be determined by a
ohmmeter when transformer leads are
disconnected. Resistance is normally less than one
ohm; filament does not short internally. Any tube
removed should be checked since usage tends to
make the filament more fragile. Later handling and
shipping may open the filament and thereby mask
the true failure mode when checked at the factory.
3. Low Power - Caused by “wearout” of the emission
characteristics of the directly heated cathode.
Symptoms are: (1) tube current will take longer to
get to operating point then a new tube (normally
about 2 - 3 seconds), (2) tube current does not get
high enough to cause the tube to oscillate with
normal line voltage, (3) oven produces low power
into a load, two-thirds or less than normal.
4. Physical Damage - Caused by mishandling of
magnetron tube.
To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires power.

Measurement with the Outer Panel
WARNING
!
Check for radiation leakage after servicing. Should the
leakage be more than 4 mW/cm
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.

WARNING
!
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.
Measurement with a Fully Assembled
Oven
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/cm
less.
• Leakage for fully assembled oven with door normally
closed ...4 mW/cm
• Leakage for a fully assembled oven (before the latch
switch (primary) is interrupted) while pulling the door
... 4 mW/cm
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.

or
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.
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.
To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires power.

Purpose of these monitors is to check radiation
leakage around microwave oven door or other places
where radiation could possibly occur.

the oven and used as a load during leakage tests.
Operate the instrument on its internal 9 Volt battery
power supply. “Range” switch is used on low and high
while using test probe. On an oven with an unknown
leakage, use high scale then switch to low scale and
test for low leakage. “Bat Test” switch is used to
check the battery and probe on the Holaday
Instruments. If either is faulty, meter needle will not
read above “Test Minimum” or battery mark on meter.
Holaday Instrument has a probe test switch position.
Meter needle must indicate in the “OK probe test”
portion of the scale when in this position. Zero control
is used to zero the needle. “ON-OFF” switch provides
a means of turning the operating voltage on or off.
“Range Multiplier” switch provides a means of
selection either 0-2 or 0-10 and 0-100 on the Holaday

WARNING
Hold probe perpendicular to cabinet door. Place cone
of probe on the door and/or cabinet door seam and
move along the seam. If leakage of the oven is
unknown, move probe slowly. Proceed with care in
order not to exceed a full scale reading of meter.
When testing near a corner or access area of door,
keep probe perpendicular to the areas making sure
probe end at the base of the cone does not get closer
than 2” (5cm) to any metal. If it does, an erroneous
reading may result.
Always use the 2” (5cm) spacer with probe. Also,
always proceed carefully in areas of high leakage or
probe can be accidentally burned-out. Rotating
antenna causes high peaks of energy. Although meter
has averaging capabilities, probe will react
instantaneously to peak power changes which will
cause burn-out.
Test probe must be held by the grip portion of the
handle, otherwise a false reading may result if
operators hand is between the handle and probe.
If oven is likely to have a large amount of leakage,
approach oven slowly with the probe, while observing
meter. This is achieved by holding the probe two or
three feet from oven surface or gap between door and
oven body while observing meter. When high leakage
is expected, do not move probe horizontally along the
oven surface. This could cause possible probe
burn-out. Greatest leakage is generally found at the
corners. After maximum leakage is established to be
within the meter scale range, then probe may be
moved horizontally around the door surface.
To avoid risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitor
before servicing, unless testing requires power.
Remove diode lead from capacitor and
