How to Fix / Troubleshooting
Safety first: Unplug the unit before working near the motor.
- Verify tach connector: Ensure the small tachometer connector on the motor is firmly attached and wires are not broken.
- Inspect motor: Check the rear of the motor for physical damage where the tach sensor mounts.
- Test tach output: A technician can spin the motor and measure AC voltage from the tach leads. No output indicates a bad tach/motor assembly.
- Replace motor or control: Replace the drive motor if the tach is faulty. If the tach signal is present but not recognized, replace the motor control or main control board.
