• Failure can cause heavy frost on the evaporator/back freezer wall
• May lead to warmer temperatures, constant running, short cycling, or no-cool if stuck in defrost

• 1 defrost timer

• Disconnect power before servicing
• Access location varies by model
• Note wire positions and transfer them one at a time to the new timer
• Mount securely in the same orientation as the original and verify normal cycling after power is restored
