Frigidaire Range Error Code F107

F107 indicates that the NIU (Network Interface Unit) has stopped communicating with the OUI (Operator User Interface), two internal control modules that must exchange data for the range to function. This is a control board communication fault, not a sensor or heating element issue. The recommended repair is to replace the electronic controls, which includes the OUI, GPU, and NIU.

The range should not be used while displaying an F107 fault. A communication failure between internal control boards means the range's controls may not function predictably or respond correctly to user input. Continuing to operate the appliance under these conditions could be unsafe. The fault should be diagnosed and repaired before resuming use.

A reset, such as unplugging the range for a few minutes and restoring power, may temporarily clear the F107 code, but the fault will typically return if the underlying hardware problem has not been fixed. Because F107 points to a hardware communication failure between control boards, a power cycle alone is not a lasting solution. The control electronics will need to be inspected and likely replaced to permanently resolve the error.

A technician with appliance repair experience can address this fault by first inspecting the wiring harnesses and connectors between the control boards for looseness or damage. If the wiring is intact, the repair requires replacing one or more of the internal control boards, specifically the OUI, GPU, and NIU assembly. This involves working inside the range's control panel area, so comfort with disassembly and handling electronics is necessary. If you are not confident working with internal electronics, a qualified appliance technician should perform the repair.

Repair costs vary depending on which control boards need to be replaced and whether you hire a technician or source parts independently. Control board assemblies for ranges generally fall in the range of $100 to $400 or more for parts, and professional labor can add $75 to $200 on top of that. Getting a diagnostic estimate from a technician before authorizing parts replacement is a good way to avoid unexpected costs.
