Push-Button Assembly - GE ZV800SJSS Technical Service Manual

FAN MOTOR TEST
The fan motor is a 2 pole induction capacitor motor. To test the resistance values of the fan motor windings:
1. Access the PCB, then disconnect the fan harness from CN1 (See
Note: Jump, then test each speed individually.
2. Jump fan harness wires, indicated in motor test chart, using appropriate jumper wire.
3. Check for proper resistance at the fan harness test wires.

RIBBON TEST
The ribbon is a 10-conductor connection between the push button and the PCB. To test the continuity of the
ribbon from the push button through the ribbon receptacle (located at the left side track) to the PCB location:
1. Access the PCB, then disconnect the ribbon from CN5. (See
2. Remove the push button, then disconnect the ribbon. (See
3. Check continuity of each individual ribbon conductor.
Note: Numbers in illustrations below represent and identify individual ribbon conductors.
