MANUAL OVEN LIGHT SWITCH (SOME MODELS)
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
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.
