CAUTION
• High voltages are present during the cook
cycle. Extreme caution should be ob-
served 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 deter-
gent or paper towels with spray glass
cleaner. Apply spray glass cleaner to pa-
per towel. Do not spray directly on oven.
• Before touching any oven component or
wiring, always unplug the oven from its
power source and discharge the capaci-
tor by using a 20,000 ohm discharge
resistor or use an insulated plastic handle
screwdriver to short across the capacitor
terminals.
• Check that the unit is grounded before
troubleshooting. 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 discharge
may damage the control circuit.
• Do not touch oven components or wiring
during operation. Attach meter leads with
alligator clips when making operational
tests.
• For continued protection against radia-
tion emission, 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-
VI6-FA-62 or VP-532A-OF; Oven Lamp
Switch: SZM-V6-FA-31 or VP-331 A-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.
• Disconnect the oven from electrical sup-
ply before 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.
Electrostatic Discharge (ESD)
Sensitive Electronics
ESD problems are present everywhere. ESD
may damage or weaken the electronic con-
trol assembly. The new control assembly
may appear to work well after repair is fin-
ished, but failure may occur at a later date
due to ESD stress.
• Use an antistatic wrist strap. Connect
wrist strap to green ground connection
point or unpainted metal in the appli-
ance, or touch your finger repeatedly to
a green ground connection point or un-
painted metal in the appliance.
• Before removing the part from its pack-
age, touch the antistatic bag to a green
ground connection point or unpainted
metal in the appliance.
• Avoid touching electronic parts or ter-
minal contacts; handle electronic con-
trol assembly by the edges only.
• When repackaging failed electronic con-
trol assembly in antistatic bag, observe
above instructions.
