COMPONENT DESCRIPTION & TESTING
OVEN LIGHT
Test Procedure
WARNING
Electrical Shock Hazard
Disconnect from electrical supply before ser-
vicing unit.
Failure to do so could result in death or
electrical shock.
If the oven light does not work:
1. Remove the oven light bulb and test it for
continuity. If the meter reads infinity, the
bulb is defective. If the meter shows con-
tinuity, reinstall the light bulb, and go to
the next step.
2. Disconnect power from the range, and
check the automatic oven light switch (and
the manual light switch, if one is installed)
for continuity with the switch contacts
closed. Also make sure that none of the
wire terminals are loose or shorted to the
chassis.
