Refrigerator not cooling at all, interior lights work but both compartments are warm.

Safety first: Unplug the refrigerator and be cautious around high-voltage components. Sealed system work should be done only by certified technicians.

Steps:

• Listen for operation: Plug the unit in and listen for the compressor and fans. If only the interior lights work and no humming or fan noise is heard, proceed.
• Check condenser fan: Remove the rear lower panel and see if the condenser fan runs. If the fan is off and the compressor is silent, suspect the control board or power supply.
• Inspect start relay and overload: With power disconnected, remove the start relay/overload assembly from the compressor terminals. Look for burn marks or rattling parts. Replace with a Magic Chef-compatible start device if damaged.
• Test compressor (advanced): Measure resistance between compressor terminals. Very high or zero readings may indicate a failed compressor.
• Control board: If the compressor and start device test good but never receive power, the main control board may be defective and require replacement.

Warning: If the compressor is locked or shorted, replacement of the compressor and recharging the system is a professional job.
