Step-by-Step Solutions

Wait for Defrost Cycle

Normal defrost cycles last 20-30 minutes. Wait to see if the code clears automatically after the cycle completes.

Safety: Do not open doors frequently during defrost cycle.

Check Defrost Timer

Locate the defrost timer (usually behind the kickplate or in the control panel) and manually advance it to see if the cycle completes.

Safety: Disconnect power before accessing internal components.

Test Defrost Heater

Use a multimeter to check the defrost heater for continuity. A reading of 0-50 ohms indicates a working heater.

Safety: Only qualified technicians should perform electrical testing.

Inspect Defrost Thermostat

Test the defrost thermostat with a multimeter. It should show continuity when cold and open when warm.

Safety: Ensure all power is disconnected before testing components.
