Possible Causes
Defective tachogenerator on motor shaft, Loose tachogenerator connector, Broken wiring between motor and control board, Faulty motor control circuit
How to Fix / Troubleshooting
Safety first: Unplug the appliance before accessing the motor or control board.
- Access motor: Remove the rear panel and locate the motor. Identify the small tachogenerator module at the rear of the motor.
- Check connection: Ensure the tachogenerator plug is firmly seated and wires are not damaged.
- Test tachogenerator: With a multimeter set to AC volts, spin the motor shaft by hand and look for a small voltage output from the tachogenerator. No output indicates a faulty tachogenerator.
- Replace components: Replace the motor or tachogenerator assembly if defective. If the tachogenerator is good, the control board's speed sensing circuit may be faulty and requires professional service.
