“DA GER” or “WAR I G.” These words mean:
DANGER
WARNING
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance
of injury, and tell you what can happen if the instructions are not followed.
You an be killed or seriously injured if you don’t
immediately follow instru tions.
You an be killed or seriously injured if you don’t
follow instru tions.

1-2
To avoid possible exposure to microwave ra-
diation or energy, visually check the oven for
damage to the door and door seal before
operating any oven. Use a microwave survey
meter to check the amount of leakage before
servicing. In the event the R.F. Ieakage ex-
ceeds 4 mw/cm2 at 5 cm, appropriate repair
must be made before continuing to service the
unit. Check interlock function by operating the
door latch. The oven cook cycle should cut off
before the door can be opened.
The door and latching assembly contains the
radio frequency energy within the oven. The
door is protected by three safety interlock
switches. Do not attempt to defeat them.
Under no ir umstan es should you try to
operate the oven with the door open.
• Proper operation of microwave ovens re-
quires that the magnetron be properly
assembled to the waveguide and cavity.
ever operate the magnetron unless it is
properly installed.
• Be sure the “RF” seal is not damaged and
is assembled around the magnetron dome
properly when installing the magnetron.
• Routine service safety procedures should
be exercised at all times.
• Untrained personnel should not attempt
service without a thorough review of test
procedures and safety information con-
tained in this Job Aid.
WARNING TO SERVICE TECHNICIANS
KitchenAid microwave ovens have a monitor-
ing system designed to assure proper opera-
tion of the safety interlock systems.
The monitor switch will immediately cause the
oven fuse to blow if the door is opened and the
primary door interlock switch and/or the sec-
ondary interlock switch contacts fail in a closed
position.
CAUTION: Repla e a blown fuse with a 20
ampere lass H fuse only.
Test the upper and lower door interlock
switches, cook relay, and monitor switch (middle
switch) for proper operation as described in the
component test procedures, before replacing
the blown oven fuse.
Do not attempt to repair sti king onta ts
of any interlo k swit h, safety swit h, or
Cook (Lat h) relay. The omponents must
be repla ed.
Any indication of sticking contacts during com-
ponent tests requires replacement of that com-
ponent to assure reliability of the safety inter-
lock system.
If the fuse is blown, the Monitor swit h, and
the Primary, and Se ondary interlo k
swit hes must be repla ed. Be sure they
are properly onne ted.

1-3
PRECAUTIONS TO BE OBSERVED BEFORE AND DURING
SERVICING TO AVOID POSSIBLE EXPOSURE
TO EXCESSIVE MICROWAVE ENERGY
A. Do not operate or allow the 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:
1)Interlock Operation
2)Proper Door Closing
3)Seal and Sealing Surfaces (Arcing,
Wear, and Other Damage)
4)Damage to or Loosening of Hinges and
Latches
5) Evidence of Dropping or Abuse
C. Before turning on the microwave power
for any service test or inspection within the
microwave generating components, check
the magnetron, wave guide or transmis-
sion 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, using procedures described in
this Job Aid, before the oven is released to
the owner.
E. A microwave leakage check to verify com-
pliance with the Federal Performance Stan-
dard should be performed on each oven
prior to release to the owner.
F. Do not attempt to operate the oven if the
door glass is broken.

1-4
R.F. LEAKAGE TEST
EQUIPMENT
• Electromagnetic energy leakage monitor
( ARDA 8100B, HOLADAY H 1501).
• 275 ±15 ML glass beaker.
TEST
On every service call, checks for microwave
energy emission must be made according to
the following manner.
1. Remove the cooking rack from the oven
cavity, if the microwave oven is so
equipped.
2. Place a 275 ±15 ML (9.3 oz.) glass of
water in the center of the oven bottom.
3. Select “HIGH” cook power, turn the micro-
wave oven on, and test for R.F. Ieakage at
the following locations:
a)Around the cabinet at the front.
b)Around the door.
c) Across the console panel.
d)Horizontally across the door.
e)Vertically across the door.
f) Diagonally across the door.
g)Across the air vents.
h)Across the rear air vent.
i) All lockseams.
j) Weld at bottom.
k) Bottom plate.
I) Oven feet.
4. The scan speed is one inch per second.
When checking for R.F. Ieakage, use an ap-
proved R.F. measuring device to assure less
than 4 mw/cm2 emission at 5 cm distance with
a maximum scan rate of 2.54 cm/second, in
compliance with U.S. Government Department
of Health, Education and Welfare 21CFR1030,
Performance Standard for Microwave Ovens.
A properly operating door and seal assembly
will normally register small emissions, but they
must be no greater than 4 mw/cm2 to allow for
measurement uncertainty.
NOTE: Enter leakage readings in space BE-
FORE and AFTER on the service document.
All microwave ovens exceeding the emission
level of 4 mw/cm2 must be reported to Dept. of
Service for Microwave Ovens immediately and
the owner should be told not to use the micro-
wave oven until it has been repaired com-
pletely.
If a microwave oven is found to operate with the
door open, report to Dept. of Service, the
manufacturer and CDRH* immediately. Also
tell the owner not to use the oven.
The monitor switch acts as the final safety
switch protecting the customer from micro-
wave radiation. If the monitor switch operated
to blow the fuse when the interlocks failed, you
must replace all interlock switches with new
ones, because the contacts of those interlock
switches may be melted and welded together.
If safety interlock/monitor switch replacement,
or adjustment, is required, you must reconnect
the circuit, and perform a continuity check on
the monitor circuit.
All repairs must be performed in such a manner
that microwave energy emissions are minimal.

PRECAUTIONS TO BE OBSERVED WHEN TROUBLESHOOTING
WARNING
DISCHARGING HIGH
VOLTAGE CAPACITORS
For about 30 seconds after the oven is
turned off, an electric charge remains in the
high voltage capacitors in the inverter power
supply circuit board.
When replacing or checking parts, remove
the power plug from the outlet. Use a screw-
driver with an insulated handle, and short the
inverter output of the magnetron filament
terminals to discharge it. Be sure to touch the
chassis ground side first, and then touch the
output terminals.
The microwave oven is a high voltage, high
current appliance. It is free from danger during
ordinary use, but extreme care should be taken
during repair.
CAUTION
Service technicians should remove their
watches whenever working close to or re-
placing the magnetron.
WARNING
There is high voltage present, with high
current capabilities in the circuits of the pri-
mary and secondary windings, the choke
coil, and the heat sink of the inverter. It is
extremely dangerous to work on or near
these circuits with the microwave oven ener-
gized. DO OT measure the voltage in the
high voltage circuit, including the filament
voltage of the magnetron.
WARNING
ever touch any circuit wiring with your
hand, or with an insulated tool during opera-
tion.
WARNING
Before touching any oven components or
wiring, always unplug the oven from its power
source, and discharge the line and high
voltage capacitors.

WARNING
GROUNDING INSTRUCTIONS
• For all cord co ected applia ces
The microwave oven must be grounded.
In the event of an electrical short circuit,
grounding reduces the risk of electric
shock by providing an escape wire for the
electric current. The microwave oven is
equipped with a cord having a grounding
wire with a grounding plug. The plug
must be plugged into an outlet that is
properly installed and grounded.
WARNING: Improper use of the grounding
plug can result in a risk of electric shock.
Consult a qualified electrician or service-
man if the grounding instructions are not
completely understood, or if doubt exists
as to whether the microwave oven is prop-
erly grounded.
Do not use an extension cord. If the power
supply cord is too short, have a qualified
electrician or serviceman install an outlet
near the microwave oven.
