How to Fix / Troubleshooting
Safety: Unplug the refrigerator before opening control compartments.
Steps to diagnose:
- 1. Confirm power: Interior lights working indicate mains power is present.
- 2. Check temperature settings: Ensure the unit is not set to an 'off' or vacation mode.
- 3. Listen for relay click: After plugging in, listen near the control board for a click indicating a call for cooling. No click may indicate a control fault.
- 4. Sensor check: A sensor reading falsely low can prevent cooling. Test and replace suspect sensors as described in sensor-related entries.
- 5. Control board inspection: Access the main PCB and look for burnt or damaged components. If present, replace the board.
Recommendation: If you are not comfortable with electronic diagnosis, contact a technician to test the board and sensors.
