Jenn-Air Range Error Code F2E3

F2E3 indicates a keypad hardware failure on a Jenn-Air range. The control system has detected a fault in the physical keypad or its connection to the user interface board. The first step in diagnosing this code is confirming that the user interface board is receiving the correct +14 VDC supply voltage at connector J900 pins J900-11 to J900-1.

A keypad hardware failure means the control system may not respond reliably to input, which can create unpredictable oven behavior. It is best to avoid using the range until the fault is diagnosed and resolved. Continuing to operate the appliance with a confirmed keypad hardware fault is not recommended.

Repair costs vary depending on which component has failed. A replacement keypad membrane typically runs in the range of $30 to $100 in parts alone. A user interface board can cost between $100 and $300 or more depending on the model. Adding professional labor will increase the total, generally bringing a full repair estimate to somewhere between $150 and $500 depending on the specific fault and service rates in your area.

Some causes of F2E3 are accessible to experienced DIYers, such as reseating a loose ribbon cable at connector J900. However, replacing the keypad membrane or the user interface board requires disassembly of the control panel and comfort working with appliance electronics. If you are not confident measuring DC voltage with a multimeter, professional service is recommended.

Cycling power to the range by unplugging it or tripping the circuit breaker for 30 seconds may temporarily clear the F2E3 code, but if an underlying hardware fault exists in the keypad, ribbon cable, or user interface board, the error will return. A power reset alone is not a repair and should only be used as an initial diagnostic step.
