Possible Causes
Fan motor seized, Compressor locked rotor, Low supply voltage, Failed start components
How to Fix / Troubleshooting
Safety: Unplug immediately if you hear loud humming without normal operation to avoid damage.
Steps to diagnose:
- Check supply voltage: Ensure the outlet provides proper voltage and is not shared with heavy loads.
- Inspect fan: Try spinning the fan blade by hand (with power off). If it is stiff or stuck, replace the fan motor.
- Compressor check: If the fan runs freely but the compressor hums and trips, the compressor may be locked or the start relay faulty. Replace the compressor start relay / PTC first.
- Professional service: If a new relay does not help, the compressor is likely failing and requires a technician.
