TESTING AN OVEN LIGHT SWITCH
The oven light switch can be a rocker-type, (see Figure 6-4A), or a pushbutton-type (see Figure
6-4B) switch. The rocker switch is manually operated, and the pushbutton switch is operated by
the oven door. The pushbutton switch may have more that two terminals, depending on the model.
The terminal callouts for the two types of pushbutton switches are shown below. NOTE: It may be
necessary to pull the range out of its location.
To test a switch:
1.
Turn off the gas and electrical power to the range.
2.
Set the ohmmeter to the R x 1 position.
3.
Touch the meter leads to the rocker or pushbutton switch terminals and operate the switch.
The meter should switch between
continuity
and
no continuity
as the switch is operated
(see the following illustrations). If the meter does not indicate a change, replace the switch.
