GE Refrigerator Error Code FRENCH DOOR ICE ROOM SENSOR

This error means the main control board has detected a problem with the ice room temperature sensor circuit. The board monitors a voltage signal between 4.5V and 1.0V from this sensor, and the error triggers when the signal falls outside that range or the reported temperature exceeds 122°F or drops below -58°F. The root cause is typically a failed thermistor, a wiring fault, or a connector issue.

The refrigerator may continue to run, but ice-making performance could be unreliable or stop entirely since the control board cannot accurately monitor the ice room temperature. Food stored in the main compartments is generally not at immediate risk, but you should address the error promptly to avoid ice system damage or further faults.

A power reset may temporarily clear the error code, but if the underlying fault in the sensor, wiring, or connector is still present, the error will return once the control board runs its diagnostic cycle again. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for proper diagnosis and repair of the root cause.

A knowledgeable DIYer can perform initial diagnostics such as inspecting the connector for corrosion or loose pins and checking wiring for visible damage. Measuring the voltage at the main PCB sensor connector requires a multimeter and basic electrical knowledge. Replacing the thermistor is generally a straightforward repair, but if the main PCB is suspect, professional service is recommended.

If only the thermistor needs replacement, parts typically cost in the range of $15 to $50, with professional labor adding $75 to $150 depending on your area. A wiring harness repair may fall in a similar range. If the main PCB requires replacement, total costs including parts and labor can range from $200 to $450 or more.
