How to Fix / Troubleshooting
Safety first: Unplug and cool the unit before working near the fan.
Steps:
- 1. Access fan motor: Remove the top cover to reach the fan and motor.
- 2. Check for rubbing: Ensure the fan blades are not scraping the shroud or heater. Adjust position if necessary.
- 3. Attempt cleaning: Blow out dust and wipe away grease around the motor shaft area. Do not soak the motor.
- 4. Lubrication (if design allows): Some motors have accessible bushings where a tiny drop of high-temperature-safe oil can be applied. If the motor is sealed, do not attempt to open it.
- 5. Replace motor if noise persists: Persistent squealing usually indicates bearing failure. Replace the fan motor assembly.
