Possible Causes
Failed run capacitor shared by fan and compressor, Seized fan motor, Seized compressor
How to Fix / Troubleshooting
Safety: Unplug the unit. Do not leave a humming, non-starting unit powered; it can overheat.
- Fan check: Try spinning the fan by hand. If it is stiff, replace the fan motor.
- Capacitor inspection: Locate the run capacitor (often metal or plastic can). If bulged or leaking, replace with the same µF rating and voltage.
- Compressor check (advanced): If the fan runs freely but the compressor only hums, the compressor may be locked. A technician should evaluate whether replacement is feasible.
