Samsung Refrigerator Error Code FE

FE on a Samsung refrigerator indicates that the freezer room temperature sensor (F-sensor) has been detected in an open or short circuit condition by the unit's self-diagnosis system. The sensor is a thermistor that the control board monitors by reading its electrical resistance. When the resistance is outside the expected range for the current temperature, the board logs the FE fault. This typically points to a failed sensor, damaged wiring, or a loose connector.

Continuing to run the refrigerator with an active FE error is not recommended, especially for food safety. The freezer temperature sensor is what the control board uses to regulate the cooling cycle, and without accurate sensor data the freezer may not maintain adequate temperatures. Food stored in the freezer could be at risk if the cooling system is not operating correctly. Address the fault as soon as possible to avoid spoilage.

Repair costs depend on which component has failed. A replacement F-sensor thermistor typically costs in the range of $15 to $50 for the part alone. If professional labor is needed, diagnostic and repair fees can add $100 to $250 or more depending on your area and the service provider. A control board replacement, if needed, is the most expensive scenario and can range from $150 to $400 or higher for parts and labor combined.

Turning the main power off and back on will trigger a new self-diagnosis cycle and may temporarily clear the code if the fault was caused by a transient electrical issue. However, if the F-sensor or its wiring has a real open or short circuit condition, the code will return after the self-diagnosis runs. A power cycle is a useful first diagnostic step, but it is not a permanent fix for a hardware fault.

Start by cycling the main power off and then back on to allow a fresh self-diagnosis. Next, inspect the F-sensor's wiring connector for looseness, corrosion, or bent pins and reseat it firmly. Use a multimeter to measure the sensor's resistance and compare it against the temperature-to-resistance table to determine if the sensor has failed. If the sensor tests out of spec, replace it. If the sensor and wiring both check out correctly, the control board may need further evaluation.
