GE Range Error Code F8x

The F8x code on a GE range indicates a fault in the CLEAR/OFF touch key circuit. The control board has detected what it interprets as a short or persistent closed signal at that key position. The two components responsible for this fault are the touch film membrane assembly and the main logic board. Identifying which one has failed requires basic diagnostic isolation between the two parts.

It is generally not advisable to continue using the range while the F8x error is active. A shorted touch key circuit could interfere with normal control panel operation and may prevent you from properly canceling cooking cycles using the CLEAR/OFF function. Until the fault is diagnosed and resolved, the range should be used with caution or taken out of service.

Repair costs vary depending on which component has failed. A touch film membrane replacement typically costs less than a main logic board and may range from around $30 to $100 for the part alone, while a main logic board can range from $100 to $300 or more. If you hire a technician, labor costs will add to those figures. Getting a diagnostic service call can help confirm the faulty part before committing to a full repair cost.

A knowledgeable DIYer can attempt basic diagnostics, such as inspecting the control panel for visible moisture or damage and disconnecting the touch film to see if the fault clears. If the touch film is the problem, replacing the membrane is a moderately involved repair that requires disassembling the control panel. Main logic board replacement is also achievable for someone comfortable working with appliance electronics, but if you are unsure about working with the electrical components of a range, professional service is recommended.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F8x code, but if the underlying short in the touch film or a logic board fault is still present, the code will return. A reset alone does not repair the faulty component. Permanent resolution requires identifying and replacing the defective touch film or main logic board.
