Display shows F5; compressor or fans may not run as expected

Safety first: Unplug the freezer before touching the compressor or electrical components. Capacitors can hold a charge; discharge safely if present.

• Listen for compressor: When powered, listen for a humming or clicking sound from the compressor area. Rapid clicking can indicate a failed start relay.
• Inspect relay and overload: Remove the cover on the side of the compressor to access the start relay and overload. Look for burn marks or melted plastic.
• Test relay (advanced): Use a multimeter to check for continuity according to the relay's specifications. Replace if open or rattling when shaken.
• Check harness: Ensure all connectors to the compressor and relay are tight.
• Call a technician: If the compressor windings test good but it will not start even with a new relay, the compressor or control board may be faulty and requires professional service.
