GE Range Error Code F125

F125 means the control board has detected a voltage signal from the Cancel touch key that is outside of its acceptable operating limits. The board monitors each key's voltage continuously, and when the Cancel key reads too high or too low, it triggers this fault. The most likely cause is a worn membrane keypad or a connection problem between the keypad and the control board.

It is generally not advisable to continue using the range while F125 is active. The fault indicates an issue with the control panel's touch key circuitry, which could affect your ability to cancel a cooking cycle or respond to other control inputs reliably. Discontinue use and diagnose the fault before operating the appliance again.

Replacing the membrane keypad is a repair many experienced DIYers can perform, as it typically involves removing the control panel fascia and disconnecting the ribbon cable connector. The critical steps are sourcing the correct keypad for your specific model and handling the ribbon cable carefully to avoid tearing it. If you are not comfortable working with appliance control panels or identifying the correct parts, a qualified technician is the safer choice.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F125 code, but it will typically return if the underlying hardware problem is not corrected. The Cancel key voltage must consistently fall within the acceptable range for the fault to stay cleared. A reset is useful for confirming whether the fault is intermittent, but it is not a permanent fix.

If the fix requires a new membrane keypad or touchpad assembly, parts typically range from around 50 to 150 dollars depending on the model, plus labor if you hire a technician. If the control board needs replacement, costs can range from 150 to 400 dollars or more for parts alone. Getting the ribbon cable connection inspected first is worthwhile since that repair may cost nothing if no parts are needed.
