To test the automatic oven light switch, per-
form the following steps:
1. Use an ohmmeter and set the range switch
to R x 1.
2. With no power applied, remove the wires
from the switch terminals.
3. Touch the leads of the ohmmeter to the
gold terminals of the switch and the meter
should indicate an open circuit (infinity
∞).
4. Press in on the switch button, and the
meter should indicate continuity.
5. Touch the leads of the ohmmeter to the
silver terminals of the switch and the meter
should show continuity.
6. Press in on the switch button and the
meter should indicate an open circuit (in-
finity ∞).
If the above results are not obtained, the switch
is defective and should be replaced.

MANUAL OVEN LIGHT SWITCH
(SOME MODELS)
Description
The automatic oven light switch contacts are
normally open when the oven door is closed
and the plunger is pushed in. When the door
opens, the plunger is pushed out, the contacts
close, and 120-volts is applied to the light,
which then turns on.
Test Procedure

Description
The manual oven light switch has two posi-
tions: one position is off, and the other is on.
When the switch is pushed to on, the colored
area of the switch rocker is exposed, and 120-
volts is applied to the oven light, which then
turns on.
Test Procedure
