GE Oven Error Code F5

The F5 error on a GE oven indicates a sensor circuit supervisor failure detected by the electronic control board. The control board continuously monitors the oven temperature sensor circuit through a supervisory function, and when it detects that the sensor circuit has fallen outside acceptable parameters, it triggers F5 and disables operation. This is a control-level fault, meaning the board itself has identified an internal or external supervisory failure rather than a simple open or shorted sensor reading. GE's first recommended action is control replacement, which points to the control board as the primary suspect.

For homeowners, the oven's main computer board watches the temperature sensor circuit to make sure it is reading correctly. When something goes wrong with how that circuit is being monitored, the board throws the F5 code as a safety measure and stops the oven from operating. In most cases, the control board itself has failed internally. Less commonly, the temperature sensor or its wiring is causing the supervisory circuit to fail. Either way, the oven will not function normally until the fault is corrected. Resetting the oven by cutting power briefly may clear the code temporarily, but F5 will typically return if the underlying component has failed.
