Possible Causes

Weak run capacitor, failing compressor relay on control board, low line voltage, failing compressor drawing locked-rotor current

How to Fix / Troubleshooting

Safety: Unplug the unit. Capacitors and high-voltage components can be dangerous.

Steps:

  • 1. Check voltage and circuit: Ensure the unit is on a dedicated circuit with proper voltage. Avoid extension cords.
  • 2. Inspect capacitor: Access the electrical compartment and visually inspect the run capacitor. Replace if bulged or leaking.
  • 3. Listen to relay: If the relay on the control board clicks repeatedly, the board may be cycling due to overload or internal failure. Replace the board if the compressor and capacitor test good.
  • 4. Professional compressor test: If the compressor hums loudly and then clicks off, it may be locked. A technician can test winding resistance and advise on replacement.
