GE Refrigerator Error Code F510

F510 on a GE refrigerator means the door control board is receiving an invalid temperature reading from the icemaker mold thermistor. The thermistor monitors the temperature of the ice mold during the freeze and harvest cycle, and when its signal falls outside an acceptable range, the board logs this fault. This typically causes the icemaker to stop functioning until the issue is corrected.

The F510 fault specifically affects the icemaker system, so the refrigerator and freezer cooling functions typically continue to operate normally. It is generally safe to use the refrigerator for food storage while the error is present. However, ice production will likely be disrupted or stopped entirely until the fault is resolved.

Repair costs depend on the root cause. A replacement icemaker mold thermistor is typically an inexpensive part, often in the range of $15 to $50 depending on the model. If the door control board needs replacement, parts alone can range from $80 to $200 or more. Adding professional labor costs will increase the total, generally ranging from $100 to $300 or higher for a complete service call.

Some causes of F510 are DIY-friendly, such as reseating a loose connector or cleaning corroded terminals. If the thermistor itself has failed, replacing it requires purchasing the correct replacement part and disconnecting power to the refrigerator before starting work. If the door control board needs replacement, that repair is more involved but still manageable for someone comfortable with appliance repairs.

A power reset may temporarily clear the F510 code, but if the underlying issue with the thermistor or wiring is still present, the code will return once the control board runs its diagnostic checks again. A reset is a reasonable first step to rule out a transient glitch, but a persistent F510 requires actual diagnosis and repair of the thermistor or wiring.
