Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the unit before touching the fan or internal wiring.
- Check for obstructions: Remove the grille and ensure nothing is blocking the fan blades.
- Spin test: Try spinning the fan by hand. If it is stiff, the motor bearings may be seized; replace the fan motor assembly.
- Capacitor test: Locate the fan capacitor (if used) and test its capacitance. Replace with the correct value if faulty.
- Electrical test (advanced): With caution and proper isolation, verify that the fan motor receives voltage when it should be running. If voltage is present but the motor does not turn, replace the motor. If no voltage, suspect the PCB fan drive circuit.
