Important Safety Information
!
CAUTION
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 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 Appliances, Inc.
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.

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 Maytag microwave oven should never be operated
with:
• Any components removed and/or bypassed.
• Any of the safety interlocks are found to be failed.
• Any of the seal surfaces are 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 Narda Model 8100, 8200,
Holaday HI1500, HI1501 or Simpson 380M leakage
monitor as outlined in the instructions. The maximum
leakage level allowed is 4mW/cm
13. If servicer encounters an emission reading over
4mw/cm 2 the servicer is to cease repair and contact
the Amana Service Department immediately for further
direction. Amana Appliances, Inc. will contact the
proper Government Agency upon verification of the test
results.
