Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the freezer before touching any electrical connections.
Steps:
- Check outlet: Test the wall socket with another appliance or a multimeter to confirm proper voltage and grounding.
- Inspect mains cable and terminal block: Access the rear lower or top electronics area and verify that the mains cable is firmly clamped and the terminal screws are tight.
- Look for burn marks: On the main PCB, inspect the power supply section for burnt components or cracked solder joints.
Remedy: If the household supply is good and connections are secure, the internal power supply on the control board may be faulty. Replacement of the main control board is usually required and is best done by a qualified technician.
