Possible Causes
Failing compressor, Defective start relay, Weak start capacitor, High head pressure from dirty condenser
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing compressor components. Capacitors can retain charge; discharge safely.
- Step 1 – Clean condenser: Ensure the condenser coil is clean and airflow is unobstructed to reduce compressor load.
- Step 2 – Inspect start components: Remove the start relay and capacitor from the compressor. Test them with a multimeter/capacitance meter and replace if defective.
- Step 3 – Listen after repair: Restore power and observe startup. If the compressor still hums and clicks off, the compressor may be locked and require replacement by a sealed system technician.
Do not repeatedly reset a tripping breaker or run a locked compressor; this can cause further damage.
