How to Fix / Troubleshooting
Safety first: Turn off power at the disconnect. Compressor terminals carry high current.
- Step 1 – Check capacitor: Test and replace the dual run capacitor as described previously.
- Step 2 – Listen for compressor: With power restored, listen for a brief hum or click from the compressor. If silent, it may be open or not receiving power.
- Step 3 – Technician testing: A professional should check voltage at compressor terminals and test winding resistance to determine if the compressor has failed.
