GE Range Error Code F107

F107 indicates a loss of communication between the NIU (Network Interface Unit) and the OUI (Oven User Interface), two internal control modules that must exchange data for the range to operate. When the NIU stops communicating with the OUI, the system triggers this fault code. The range will not function normally until the communication link is restored.

Cycling power to the range by unplugging it or switching off the circuit breaker for a few minutes may temporarily clear the code, but it is very likely to return if the underlying communication fault is still present. A reset does not repair a failed board or a damaged wiring connection. The error will persist until the root cause is corrected.

Repair costs vary depending on which components need to be replaced and local labor rates. If only a harness connector needs reseating, the cost may be limited to a service call fee, typically in the range of $75 to $150. If one or more control boards require replacement, parts and labor combined can range from $200 to $600 or more depending on the specific model and board pricing.

A confident DIYer can start by checking that all wiring harnesses between the control boards are firmly seated and free of corrosion. However, if the connectors look intact, the fix requires replacing the electronic control boards, which involves working inside the control panel and sourcing the correct parts. Most homeowners will want a qualified appliance technician for the board replacement portion of the repair.

It is not recommended to continue using the range while F107 is active. The communication failure between control modules means the oven may not respond correctly to user inputs or may not regulate temperature properly. Discontinue use until the fault is diagnosed and repaired to avoid potential safety issues.
