Refrigerator not cooling at all; both fresh food and freezer sections warm, interior lights work but no cooling.

Safety first: Unplug the refrigerator before removing the rear access panel. Do not attempt to open sealed system lines; refrigerant work must be done by a licensed technician.

• 1. Listen for operation: With the unit plugged in, listen at the back. A quiet hum from the compressor and condenser fan indicates they are running. Total silence suggests a control or power issue.
• 2. Check condenser fan: Remove the rear lower panel and verify if the condenser fan runs when the unit calls for cooling. If the fan is off and the compressor is off, suspect a control issue.
• 3. Verify basic power: Confirm the outlet has power and the cord is firmly plugged in. Check the household breaker.
• 4. Inspect main control board: Look for burned components or loose connectors. Reseat all plugs.
• 5. If compressor is hot and clicking: A failed start device or inverter is likely. These can often be replaced without opening the sealed system.
• 6. Call a technician: If the compressor does not start even with a new start device/inverter, or if it runs but no cooling occurs, sealed system diagnosis and repair are required.
