Refrigerator not cooling, interior light works, compressor does not start at all

Safety first: Always unplug the appliance before removing covers or touching wiring.

• Confirm power and lights: Verify that the interior light turns on when the door opens, confirming mains power is present.
• Check compressor temperature: Carefully touch the compressor shell at the back. If it is stone cold after being plugged in for over 30 minutes, it is likely not receiving power.
• Inspect wiring and overload: Remove the rear lower panel. Inspect the wiring harness to the compressor for burns or loose connectors. Ensure the overload protector (small device clipped to compressor) is firmly attached.
• Reset by power cycle: Unplug the fridge for 10 minutes, then plug it back in. Some control boards may reset and attempt to start the compressor again.
• Listen for relay click: If there is no click or hum from the compressor area at all, the main control board may not be sending power.
• Do not bypass safety devices: Never bypass the overload protector or relay; this can cause fire or compressor damage.
• Next step: If wiring and connectors look intact and the compressor is not attempting to start, the main control board or compressor windings need electrical testing with a multimeter. This should be done by a qualified technician.
