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

finity ∞).
If the above results are not obtained, the switch
is defective and should be replaced.

opens, the plunger is pushed out, the contacts
close, and 120-volts is applied to the light,
which then turns on.
