GE Refrigerator Error Code F10

F10 on a GE refrigerator indicates that the freezer icemaker mold body thermistor (MB) is sending an invalid signal to the control board. This code does not apply to Café models. The thermistor is a temperature sensor in the icemaker mold, and when its resistance falls outside the expected range, the board flags the error and may suspend icemaker operation.

A reset may temporarily clear the F10 code, but it will return if the underlying fault with the mold body thermistor or its wiring is not corrected. Unplugging the refrigerator for a few minutes can reset the control board, but this is not a repair. The thermistor or wiring issue needs to be diagnosed and resolved to permanently clear the code.

Repair costs depend on which component has failed. A replacement thermistor or icemaker assembly can range from roughly 20 dollars to 150 dollars or more for parts, depending on the specific model. If a technician is needed for diagnosis and installation, labor costs typically add another 75 dollars to 200 dollars. Replacing only the wiring harness or cleaning a corroded connector is generally the least expensive fix.

Start by checking the resistance of the mold body thermistor using a multimeter. If the reading is open (infinite resistance) or shorted (near zero), the thermistor needs to be replaced. Also inspect the wiring harness and connector between the thermistor and the control board for damage, corrosion, or loose connections. If all wiring is intact and the thermistor resistance is correct, the control board may be at fault.

F10 is not a safety hazard in the way that a gas leak or electrical fire would be. It is a component monitoring fault that affects icemaker operation. The refrigerator's cooling system should continue to function normally. However, leaving the fault unaddressed may keep the icemaker from producing ice, and in some cases the control board may restrict icemaker cycles to prevent damage.
