Component Testing Procedures
Illustration Component Test Procedure Results
Oven light housing Disconnect connector and test
resistance of terminals ...........................
Measure voltage at oven light................. Verify bulb is plugged in properly.
Indicates continuity with bulb installed.
12 VAC, see wiring diagram for terminal
identification.
If no voltage is present at oven light,
check wiring or light switches.

Secondary Secondary
Step-down
transformer Measure voltage at:
Primary terminals ................................
Secondary terminals ...........................
120 VAC (tolerance: 108 to 127 VAC)
10W load (bulb): 11.4 to 11.8 VAC
20W load (bulb): 10.8 to 11.4 VAC
Door plunger switch Remove switch from unit and measure
the following points:
COM to NO .........................................
Plunger in continuity, plunger out infinity.
Autolatch assembly Disconnect wires and test for
continuity per wiring diagram.
Refer to Parts Manual for correct
autolatch switch associated with the
correct manufacturing number. See wiring diagram for schematic layout.
Access assembly by removing two
screws from the front and lowering
control panel.
Common is in neutral position unless
locking or unlocking autolatch assembly.
