How to Fix / Troubleshooting
Safety first: Unplug the dryer before accessing the motor.
Access the motor:
- Remove the rear or side panel to expose the drive motor.
- Locate the small tachometer coil or sensor at the rear of the motor.
Check connections:
- Ensure the tachometer connector is firmly seated.
- Inspect the wiring harness for damage.
Test tachometer:
- Measure resistance across the tachometer terminals; compare with service data. An open circuit indicates a failed sensor.
Replace the motor or tachometer assembly if defective. If wiring and sensor are good, the motor control circuit on the main PCB may be at fault.
