Possible Causes
Faulty temperature control or thermistor, Weak compressor start relay, Overheating compressor, Incorrect thermostat calibration
How to Fix / Troubleshooting
Safety first: Unplug the freezer before accessing the compressor or control board.
- Step 1 – Check temperature setting: Ensure the setpoint is reasonable (around 0°F). Extremely low settings can cause frequent cycling.
- Step 2 – Clean condenser and ensure airflow: Overheating due to poor ventilation can cause the overload to trip repeatedly.
- Step 3 – Listen to compressor: If it clicks on and off quickly without running smoothly, the start device may be failing. Replace the compressor start relay/overload if suspect.
- Step 4 – If problem persists: A failing compressor or control board may be at fault and should be evaluated by a technician.
