Important Safety Information

!
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 microwave oven to maintain this
safety. These are as follows:
1. Always operate unit from an adequately grounded
outlet. Do not operate on a two-wire extension cord.
2. Before servicing unit (if unit is operable) perform
microwave leakage test.
3. The oven should never to operated if the door does
not fit properly against the seal, hinges or hinge
bearings are damaged or broken; the choke is
damaged, (pieces missing, etc.); or any other visible
damage can be noted. Check choke area to ensure
that this area is clean and free of all foreign matter.
4. If the oven operates with door open and produces
microwave energy, take the following steps:
A. Tell the user not to operate the oven.
B. Contact Amana Refrigeration, Inc. immediately.
5. Always have oven disconnected when the outer case
is removed except when making "live" tests called
for in the service manual. Do not reach into
equipment area while unit is energized. Make all
connections for the test and check them for tightness
before plugging cord into outlet.
6. Always ground capacitors on magnetron filter box
and H.V. capacitor with an insulated-handle
screwdriver before working in high voltage area of
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
ground, etc.
8. Do not for any reason defeat interlock switches -
there is no valid reason for this action at any time;
nor will it be condoned by Amana.
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 handle is actuated. The monitor
switch MUST close at 1/4 inches when the door is
opened. (See Service Section for detailed
instructions.
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 Amana microwave oven should never be
operated with:
• Any components removed and/or bypassed.
• Any of the safety interlocks are found to be
defective.
• 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 Department of
Health and Human Services guidelines check oven
for microwave leakage using Narda Model 8100,
8200, Holaday HI1500, HI1501, or Simpson 380M
leakage monitor as outlined in instructions on the
following page. The maximum leakage level allowed
is 4mw/cm 2 .
13.If servicer encounters an emission reading over
2
4mw/cm the servicer is to cease repair and contact
Amana Service Department immediately for further
direction. Amana Refrigeration, Inc. will contact the
proper Government Agency upon verification of the
test results.
