TROUBLESHOOTING
PROBLEM: FAN MOTOR DOES NOT OPERATE
Corrective Action
Close the oven door.
Make sure oven is in an operating mode.
Test door switch. See page 8-5.
If necessary, securely connect Molex connector to motor.
Inspect bracket, and spacers between bracket and cavity
wall. Replace a distorted bracket and/or damaged
spacers.
Check motor windings resistance.
Check motor seals for wear or misalignment. Replace
seals if necessary. See page 8-41.
Disconnect oven from branch circuit and let motor cool.
Disconnect motor wires from harness. Refer to schematic
diagram and check continuity between thermal switch
terminals. Replace motor if ohmmeter reading is high.
See page 8-41.
Completely stop motor, then restart motor and measure
start windings (red wire) current. Current should be
approximately 6.0 amps then drop to 1.5 amps. If this
does not happen, harness or capacitor is defective.
When oven power is turned on, there is high
voltage present in the electrical components
compartment.
