GE Refrigerator Error Code F82

F82 on a GE refrigerator means the door board ice box thermistor is producing an invalid reading. The door control board cannot interpret the temperature signal from the sensor located in the ice compartment. This is typically caused by a failed thermistor, wiring issue, or connection problem between the sensor and the door board.

The refrigerator may continue cooling during an F82 fault, but ice production and temperature monitoring in the ice compartment could be affected. Running the unit long-term without addressing the sensor fault is not recommended, as the system may not accurately track temperatures in that zone. It is best to diagnose and resolve the issue promptly to avoid potential food safety concerns.

Repair costs vary depending on the faulty component. A replacement ice box thermistor typically costs in the range of $15 to $50 for parts alone. A door control board replacement can range from $80 to $200 or more for the part, with additional labor costs if a technician performs the repair. Wiring harness issues may only require a connector repair or minor parts at lower cost.

Some causes of F82 are DIY-friendly, such as reseating a loose connector or inspecting the wiring harness for visible damage. If the thermistor itself has failed, replacing it requires basic electrical knowledge and a multimeter to confirm the diagnosis. Door board replacement is more involved and may be better suited to a technician if you are not comfortable working with appliance electronics.

A reset may temporarily clear the F82 code, but the fault will return if the underlying problem is not repaired. Resetting without fixing the thermistor, wiring, or board does not address the root cause. Use a reset only as a way to confirm whether the fault is intermittent or persistent after completing a repair.
