GE Oven Error Code F79

F79 means the oven's control board has detected a fault with the T012 glass touch input panel. The board is not receiving a valid signal from the touch surface, which prevents the oven from accepting user input. The fault can stem from a loose wiring harness connection or a failed glass touch panel.

No. F79 locks out the touch interface, meaning the oven will not accept input commands for temperature or cook mode selection. Attempting to operate the oven in this state is not possible through normal controls. The fault must be resolved before the oven can be used safely.

A power reset by unplugging the oven or tripping the breaker for 30 seconds may temporarily clear the F79 display, but the code will return if the underlying problem with the T012 glass touch or its wiring harness is not corrected. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

Start by unplugging the oven or turning off the breaker, then accessing the control panel area to check that the harness plugs connecting the T012 glass touch are fully seated and that no wires are visibly damaged. If the connections are secure and undamaged, the next step is replacing the T012 glass touch panel. If replacing the glass touch does not clear the code, the main control board may need replacement.

If the fix is simply reseating a loose harness connector, there is no parts cost. A replacement T012 glass touch panel typically ranges from $50 to $150 depending on the specific GE model. If the main control board is also at fault, boards can range from $100 to $250 or more. Professional labor for this repair generally runs one to two hours, so factor in $100 to $200 for service if you are not doing it yourself.
