Important Safety Information
!
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.

CAUTION
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
1
close at a / –inch (0.5 mm) when the door is
64
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
/ –inch (0.5 mm) or less.
64
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/cm
13.If servicer encounters an emission reading over
2
4 mw/cm 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.
