Possible Causes

Failed compressor start relay, Faulty main control board, Open thermal protector on compressor, Incorrect temperature sensor readings preventing start

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before accessing the compressor or control board.

Steps:

  • 1. Listen for clicks: Plug in and listen for a click from the compressor area. Repeated clicking suggests a bad start relay.
  • 2. Check start relay: Remove the relay/overload from the compressor and inspect for burning or rattling pieces. Replace with an OEM Ikea-compatible start device if faulty.
  • 3. Sensor check: Faulty temperature sensors can prevent the board from calling for cooling. Test sensors as described in sensor-related faults.
  • 4. Control board: If the start device and sensors are good but the compressor never receives power, the main control board may be defective and require replacement.

Note: Do not bypass safety devices to force the compressor on; this is dangerous.
