What F107 means on a GE range

The F107 error code on a GE range indicates a loss of communication between the OUI (Oven User Interface) and the NIU (Network Interface Unit). These two control modules work together to manage oven functions, relaying user inputs and operational commands across an internal communication network. When the NIU stops transmitting data to the OUI, the system detects the communication break and triggers the F107 fault to alert the user and halt potentially unsafe operation.

This type of communication failure is most commonly caused by a fault within one of the control boards themselves, though wiring harness issues between the modules can also disrupt the data signal. Connector corrosion, a damaged ribbon cable, or a loose harness pin can all interrupt the communication link without a complete electrical failure of either board. Power surges or fluctuations can also corrupt the firmware or damage the communication circuitry on either the OUI or NIU.

Because the diagnostic path points directly to replacing the electronic controls, including the OUI, GPU (General Processing Unit), and NIU as a set, the failure is generally not considered field-repairable at the component level. Technicians should inspect wiring and connectors first, as a loose or corroded connection is a simpler and less costly fix. If harnesses and connectors check out, board replacement is the recommended corrective action.

Common causes of F107

  1. 01

    Failed NIU or OUI Control Board

    Part replacement

    One or both of the communication boards has internally failed, preventing data from being transmitted or received. This is the most common root cause and typically requires board replacement.

  2. 02

    Loose or Disconnected Wiring Harness

    Wiring / connection

    The harness connecting the OUI and NIU can work loose over time due to vibration or heat cycling. Inspect all connectors between the boards for secure seating and signs of physical damage.

  3. 03

    Corroded or Damaged Connector Pins

    Wiring / connection

    Moisture or heat exposure can cause pin corrosion at the board connectors, degrading the communication signal. Visually inspect pins for discoloration, oxidation, or bent contacts.

  4. 04

    Power Surge Damage

    Part replacement

    A voltage spike can damage the communication circuitry on the OUI, GPU, or NIU without visibly burning the board. If the error appeared after a power event, board damage should be suspected.

  5. 05

    Damaged Ribbon Cable or Signal Wire

    Part replacement

    A pinched, cut, or heat-damaged signal cable between modules will break the communication link. Carefully trace and inspect any ribbon or data cables for visible damage.

Frequently asked questions about F107

What does F107 mean on a GE range?
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.
Can I fix the F107 error myself, or do I need a technician?
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.
Will resetting the range clear the F107 error code?
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.
Is it safe to use my GE range while F107 is displayed?
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.
How much does it cost to repair the F107 error on a GE range?
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.
