Refrigerator not cooling in both fridge and freezer compartments, interior light works but temperatures are warm.

Safety first: Unplug the IceKing refrigerator before accessing the compressor compartment. High voltage is present when powered.

Steps:

• 1. Listen and feel: When plugged in, do you hear the compressor hum or click? If completely silent and warm inside, suspect the start relay or control.
• 2. Access compressor: Remove the rear lower panel. Locate the compressor, start relay/PTC, and overload protector.
• 3. Inspect relay and overload: Remove the relay/overload assembly from the compressor terminals. Check for burnt smell, discoloration, or rattling parts. Replace if damaged.
• 4. Test compressor windings: With the relay removed and power disconnected, measure resistance between compressor terminals and to ground. Open or shorted windings indicate a failed compressor.
• 5. Control check: If the compressor and relay are good, the main PCB may not be energizing the compressor. This requires further electrical diagnosis and likely PCB replacement by a technician.

Warning: Compressor replacement involves refrigerant handling and must be done by a certified refrigeration engineer.
