Samsung Refrigerator Error Code F-1 segment d

The F-1 segment d code indicates a freezer fan motor failure or a defect in the fan motor's feedback signal circuit on Samsung T/E/W model refrigerators. The main PCB monitors the freezer evaporator fan and triggers this code when it detects the motor is not operating correctly or the feedback signal is absent. The first step is checking the voltage between CN72 pins 5 and 4 on the main PCB, which should read between 7V and 12V.

Continued use is not recommended, as a non-functioning freezer fan will prevent proper cold air circulation throughout both the freezer and fresh food compartments. Food safety is at risk if temperatures rise above safe levels. Address the fault as soon as possible to avoid food spoilage or further component damage.

Repair costs vary depending on the root cause. If only the freezer evaporator fan motor needs replacement, parts and labor typically range from around $100 to $250. If the main PCB is the cause, costs can range from $200 to $400 or more depending on the model and labor rates in your area. A diagnostic visit from a technician is usually needed to confirm the exact cause before pricing can be finalized.

Some causes of this error, such as ice buildup blocking the fan blade, can be resolved by a homeowner through a manual defrost cycle. However, diagnosing electrical faults at the main PCB connector CN72 or replacing the fan motor requires a multimeter and basic wiring knowledge. If you are not comfortable working with appliance electronics, a qualified technician is recommended.

A power reset may temporarily clear the code, but it will return if the underlying fault with the freezer fan motor or its circuit has not been corrected. Resetting without repairing the root cause does not fix the problem and may delay necessary repairs while the refrigerator continues to operate outside safe temperature ranges.
