How to Fix / Troubleshooting
Safety: Unplug the unit before internal inspection.
- Usage pattern: Reduce door openings and avoid leaving the door open for extended periods.
- Check fan: Ensure the internal circulation fan runs regularly. Replace if intermittent or noisy.
- Sensor check: Compare displayed temperature with a reliable thermometer. Replace the cabinet NTC sensor if readings are inconsistent.
- Control settings: Some models allow adjusting hysteresis or differential; consult the manual and set to a smaller differential if possible.
- PCB: If all hardware is good but swings persist, the main control PCB may be faulty and require replacement.
