WARNING
!
To avoid risk of electrical shock, injury, or death, make
sure these grounding instructions are followed.
Grounding Instructions
WARNING
!
Do not remove grounding prong when installing
grounded appliance in a home or business that does
not have three wire grounding receptacle, under no
condition is grounding prong to be cut off or removed.
It is the personal responsibility of the consumer to
contact a qualified electrician and have properly
grounded 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 grounded three prong
receptacle or the two prong adapter properly grounded
by a qualified electrician in accordance with appropriate
electrical codes.
Servicing of Grounded Products
The standard accepted color coding for grounding wires
is GREEN or GREEN WITH YELLOW STRIPE. These
ground leads are NOT to be used as current carrying
conductors. It is extremely important that the technician
replace any and all grounds prior to completion of the
service call. Under no condition should ground wire be
left off causing a potential hazard to technicians and
consumer.
Important Product Information
WARNING
!
Precautions to be observed before and during
servicing to avoid possible exposure to excessive
microwave energy.
(A) Do not operate or allow oven to be operated with
the 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, wave guide
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 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.

CAUTION
!
Do not become exposed to radiation from the
microwave generator or other parts conducting
microwave energy.
Basic design of this 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. Oven should never be operated if door does not fit
properly against seal, hinge/hinge bearings are
damaged or broken; 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. If any above
problems occur take the following steps:
• Tell the user not to operate the oven.
• Contact Amana mmediately.
4. If oven operates with door open and produces
microwave energy, take the following steps:
• Tell the user not to operate the oven.
• Contact Amana immediately.
5. Always have oven disconnected when 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 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 unit is
operating, keep 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.
Important Safety Information 9. 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
10.To ensure that 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.
Maximum leakage level allowed is 4mw/cm2 .
11.If servicer encounters an emission reading over
4mw/cm2, servicer is to cease repair and contact
Amana Service Department immediately for further
direction. Amana will contact the proper government
agency upon verification of test results.
