Component Testing Procedures

WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to oven before servicing, unless

testing requires power.

Component Testing Procedures

Illustration Component Test Procedure Results

Oven light housing

All models

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.

Primary

Secondary

Step-down

transformer

All models

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

All models

Remove switch from unit and measure

the following points:

COM to NO.........................................

Plunger in continuity, plunger out infinity.

Autolatch assembly

All models

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.
