which is turned on by an oven light switch located on the air
intake panel.
If the oven light will not turn on:
1. Check the oven light bulb and replace if necessary.
2. Check the oven light switch for continuity. If none,
replace the oven light switch.

of this service manual. Replace by process of elimination
to locate any faulty parts.
