INSTRUCTIONS
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
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 radiation
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.
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
the wrist strap to a green ground con-
nection point or unpainted metal in the
appliance; or touch your finger repeat-
edly to a green ground connection point
or unpainted 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 the electronic
control assembly by the edges only.
•
When repackaging the failed electronic
control assembly in an antistatic bag,
observe the above instructions.
