GE Range Error Code F720

F720 indicates an internal touch key chip signal error on the Main Logic Board of your GE range. The touch key chip processes input signals from the control panel, and this code means that chip has failed or is producing an unacceptable signal. The fault is internal to the board and requires Main Logic Board replacement to resolve.

It is generally not advisable to continue using the range while F720 is active. A logic board fault can cause unpredictable control behavior, which may result in burners or the oven not operating correctly. Until the board is replaced and the error is cleared, the range should be treated as unreliable.

A hard reset by disconnecting the range from power for several minutes is worth attempting as a first step, since a transient electrical glitch could theoretically trigger a one-time F720 code. However, if the code returns after power is restored, the touch key chip on the Main Logic Board has failed and the error will not clear until the board is replaced. A reset alone will not fix a physical board failure.

The only confirmed fix for F720 is replacing the Main Logic Board. If you are comfortable working with appliance electronics, disconnecting power and installing a replacement board is a task some experienced DIYers can perform. However, working on range electronics involves risk, and if you are not confident, hiring a qualified appliance technician is the safer choice.

The cost to repair F720 typically involves the price of a replacement Main Logic Board plus labor if a technician is hired. Board replacement parts for GE ranges generally range from roughly $150 to $400 depending on the model, and professional labor can add another $100 to $200 on top of that. Getting a repair estimate before committing can help you decide whether repair or replacement of the range makes more financial sense.
