Freezer display shows CF1; some functions may be disabled

Safety first: Disconnect power before removing interior panels or handling wiring.

• Access evaporator area: Remove freezer drawers and the rear interior panel to expose the evaporator and fan assembly.
• Inspect wiring harness: Check the harness from the fan motor to the cabinet pass-through for damage, pinching, or ice intrusion. Reseat all connectors firmly.
• Check for ice buildup: Ice around the fan can stress the motor and wiring. Defrost the area completely using a hair dryer on low (do not overheat plastic) or by leaving the unit unplugged with doors open.
• Test fan motor: With the fan disconnected and power off, measure resistance across the motor terminals. An open circuit or obvious burn marks indicate a failed motor. Replace the evaporator fan motor assembly if defective.
• Control board consideration: If wiring and fan are good, the main control board may not be communicating properly. Board replacement is usually required and may be best left to a technician.
