Frigidaire Range Error Code F65

F65 on a Frigidaire range indicates a keyboard short circuit or an internal Electronic Oven Control (EOC) board failure. The control system has detected an abnormal signal in the touch panel matrix circuit. This fault disables normal oven operation until the underlying issue is diagnosed and corrected.

It is not recommended to operate the range while F65 is active. A keyboard short circuit could cause unintended oven activation or erratic control behavior. Disconnect power to the range until the touch panel and EOC have been properly tested and the fault has been resolved.

Repair costs depend on which component is at fault. A replacement touch panel typically ranges from around $50 to $150 in parts, while a replacement EOC board can range from $100 to $300 or more depending on the model. Adding professional labor costs will increase the total, generally bringing a full repair into the $150 to $500 range depending on the part required and local rates.

Resetting the range by cutting power at the breaker for several minutes may temporarily clear the F65 code, but it will return if the underlying fault is still present. A shorted keyboard membrane or a failed EOC board will continue triggering the fault after each reset. A reset alone is not a repair.

The correct first step is to test the keyboard circuits using the touch panel test matrix to determine whether the membrane has a shorted zone. If the touch panel tests as defective, it should be replaced. If the panel tests correctly, the fault is internal to the EOC board, which will also require replacement. Both repairs involve disconnecting power before beginning any work.
