TROUBLESHOOTING
Before testing any of the components, perform
the following checks:
The most common cause for control failure •
is corrosion on connectors. Therefore,
disconnecting and reconnecting wires will
be necessary throughout test procedures.
All tests/checks should be made with a •
VOM or DVM having a sensitivity of 20,000
ohms-per-volt DC, or greater.
Check all connections before replacing •
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
Resistance checks must be made with •
power cord unplugged from outlet, and
with wiring harness or connectors
disconnected.

DANGER
Electrical Shock Hazard
Only authorized technicians should
perform diagnostic
voltage measurements.
After performing voltage measurements,
disconnect
power before servicing.
Failure to follow these instructions can
result in death or
electrical shock.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before
operating.
Failure to do so can result in death or
electrical shock.
When performing live voltage measurements, you must do the following:
Verify the controls are in the off position so that the appliance does not start when energized.
Allow enough space to perform the voltage measurements without obstructions.
Keep other people a safe distance away from the appliance to prevent potential injury.
Always use the proper testing equipment.
After voltage measurements, always disconnect power before servicing.
