Samsung Refrigerator Error Code F-1 (C-FAN segment)

The F-1 code in the C-FAN segment indicates the main PCB has detected a problem with the machine room condenser fan motor circuit. The fault can be caused by a contact error in the feedback signal line, physical separation of the motor wiring, or a failed motor. The first step is to measure voltage at main PCB connector CN75 between the Sky-blue and Gray wires, which should read between 7V and 12V in a healthy system.

Continuing to run the refrigerator with a condenser fan fault is not recommended. The condenser fan removes heat from the machine room, and without it operating correctly, the compressor can overheat and sustain damage. Food safety may also be compromised if cooling performance drops. It is best to address the fault promptly.

A reset may temporarily clear the error code, but it will return if the underlying fault in the condenser fan motor circuit has not been resolved. The code is triggered by an active electrical fault, such as missing or out-of-range voltage on the CN75 feedback line, so clearing it without fixing the root cause only delays the diagnosis. Proper troubleshooting of the wiring, connectors, and motor is necessary for a permanent resolution.

Some causes of this error are DIY-friendly, such as reseating a loose connector at CN75 or repairing a visually damaged wire in the harness. If the issue is a failed condenser fan motor or a faulty main PCB, those repairs involve component replacement and require basic electrical testing skills using a multimeter. If you are not comfortable working near the machine room components or testing live circuits, a qualified technician should perform the repair.

Repair costs vary depending on the root cause. If the fix is a reseated connector or a minor wiring repair, costs may be minimal. A condenser fan motor replacement typically runs in the range of $50 to $150 for the part, plus labor if a technician is used. A main PCB replacement is more expensive, generally ranging from $150 to $400 or more for the part depending on the model.
