Samsung Refrigerator Error Code FRIDGE-SENSOR ERROR

This error indicates that the fresh food compartment temperature sensor has failed or lost proper connection with the main control board. The board detects a temperature reading above 149°F (65°C) or below -58°F (-50°C), which signals an invalid sensor reading rather than an actual temperature condition. Possible causes include a loose sensor, a wiring fault, or a failed thermistor. The voltage at the sensor circuit on the main PCB should read between 1.0V and 4.5V under normal conditions.

The fresh food compartment may not maintain correct temperatures while the sensor error is active, because the control board relies on accurate sensor data to regulate the cooling cycle. Food safety can be compromised if temperatures rise into unsafe ranges without triggering a proper response. It is advisable to check actual compartment temperatures with a thermometer and address the error promptly rather than continuing to use the refrigerator without a functioning sensor.

A power reset may temporarily clear the error code from the display, but if the underlying sensor fault, wiring issue, or component failure remains, the error will return. The control board will continue to detect an out-of-range voltage reading at the sensor circuit and reactivate the error. A reset is useful for confirming whether the fault is intermittent, but it does not resolve the root cause.

Some causes of this error, such as a disconnected sensor housing or a loose wiring connector, can be corrected without specialized tools. Reseating the sensor in its mounting clip and firmly reconnecting the harness plug are reasonable first steps. If the thermistor itself has failed or wiring is broken, part replacement will be required. A multimeter is helpful for checking the voltage at the main PCB connector and confirming whether the fault is in the sensor or the wiring.

If only the temperature sensor needs replacement, parts costs are typically in the range of $15 to $60 depending on the specific model. Professional labor for diagnosis and sensor replacement generally adds $80 to $200. If the main PCB is the root cause, part costs are significantly higher, often ranging from $150 to $400 or more for the board alone.
