Error F7 is displayed and the compressor may not start, or the unit may click repeatedly without cooling.

Safety warning: Unplug the refrigerator before touching the compressor or its wiring. The compressor area can be hot and contains live electrical parts when powered.

Steps:

• 1. Access compressor compartment: Remove the rear lower cover to expose the compressor, start device, and wiring.
• 2. Listen and observe: After plugging in (for diagnosis only), listen for clicking from the start relay or inverter. Then unplug again before proceeding.
• 3. Inspect start device: Remove the plastic start relay/overload from the compressor pins. Check for burnt smell, rattling pieces inside, or melted housing. Replace if damaged.
• 4. Check wiring and terminals: Ensure all wires are firmly attached and terminals are not burnt or loose.
• 5. Inverter models: If your Ikea refrigerator uses an inverter compressor, inspect the inverter module for burn marks. Replacement of the inverter module is often required if faulty.
• 6. Compressor test: Measuring compressor winding resistance and insulation should be done by a professional. If the compressor is electrically open or shorted, it will need replacement by a licensed refrigeration technician.

Note: Sealed system and compressor work requires specialized tools and must comply with refrigerant handling regulations.
