Possible Causes

How to Fix / Troubleshooting

Safety: Unplug before removing any covers.

Steps:

  • 1. Confirm outlet power: Test the wall outlet with another appliance.
  • 2. Check control settings: Ensure the freezer is not in an off or demo mode and that the temperature is set correctly.
  • 3. Inspect wiring at terminal block: Tighten any loose connections and look for burnt wires.
  • 4. Check thermal fuse (if fitted): Some IKEA freezers have a thermal fuse in series with the compressor circuit. Test for continuity and replace if open.
  • 5. Replace control board: If power is present and safety devices are intact but the compressor and fan never receive power, the main control board is likely faulty.
