CAUTION
• High voltages are present during the cook
cycle. Extreme caution should be observed
at all times.
• Abrasive cleansers, steel-wool pads, gritty
wash cloths, etc. can damage the control panel
and the interior and exterior oven surfaces. Use
a sponge with mild detergent or paper towels
with spray glass cleaner. Apply spray glass
cleaner to paper towel. Do not spray directly
on oven.
• Before touching any oven component or wir-
ing, always unplug the oven from its power
source and discharge the capacitor by using a
20,000 ohm discharge resistor or use an insu-
lated plastic handle screwdriver to short across
the capacitor terminals.
• Check that the unit is grounded before trouble-
shooting. Be careful of the high voltage circuits.
Discharge any static charge from your body by
touching ground before handling any part of the
circuitry on the control board. Electrostatic dis-
charge may damage the control circuit.
• Do not touch oven components or wiring dur-
ing operation. Attach meter leads with alligator
clips when making operational tests.
• For continued protection against radiation emis-
sion, replace only with these types of switches:
Primary (Interlock) Switch: SZM-V16-FA-63 or
VP-533A-OF; Secondary (Interlock) Switch:
SZM-V01-FA-32; Interlock (Monitor) Switch:
SZM-Vl6-FA-62 or VP-532A-OF; Oven Lamp
Switch: SZM-V6-FA-31 or VP-331A-OD.
• It is neither necessary nor advisable to attempt
measurement of high voltage.
• Attaching the adaptor ground terminal to the
wall receptacle cover screw does not ground
the appliance unless the cover screw is metal
and not insulated and the wall receptacle is
grounded through the house wiring.
WARNING
• Disconnect the oven from electrical supply be-
fore servicing. Failure to do so could result in
electrical shock or death.
• Improper use of the grounding plug can result
in a risk of electrical shock. Do not, under any
circumstance, cut or remove the third ground
prong from the power cord plug.
Fire, Electrical Shock, Excessive
Exposure to Microwave Energy,
Personal Injury & Product
Damage Hazard
• Do not block the rear air intake openings or
exhaust vents. Allow a few inches of space at
the back of the oven where intake openings
and exhaust vents are located. Blocking the air
intake openings and exhaust vents can cause
damage to the oven and poor cooking results.
Make sure the microwave oven legs are in
place to ensure proper airflow.
• Do not install the oven next to or over a heat
source (a cooktop or range).
• Do not install oven in any area where exces-
sive heat and steam are generated. This could
cause fire, electrical shock, excessive exposure
to microwave energy, other personal injury or
damage to the outside of the cabinet.
