Jenn-Air Oven Error Code F2E4-2

F2E4-2 indicates an HMI over-temperature fault caused by a shorted temperature sensor in the Human Machine Interface, which is the control panel assembly. The sensor short sends an invalid signal to the main control board, which triggers a shutdown to protect the electronics. This is a control panel electronics issue, not a problem with the oven's cooking temperature or heating elements.

The oven should not be used while this fault code is active, as the control panel is not functioning reliably and the oven has shut down as a protective measure. Attempting to bypass the fault and operate the oven could risk further damage to the control electronics. Disconnect power and have the unit inspected before resuming use.

Repair costs vary depending on whether the issue is a wiring connection or a failed HMI assembly. A wiring fix may involve minimal cost if done as a DIY repair. If the HMI board requires replacement, parts alone typically range from $150 to $400 or more depending on the model, with professional labor adding an additional $100 to $200. Getting a diagnosis from a certified technician first is recommended to confirm which component has failed.

Disconnecting power may temporarily clear the code, but if the underlying sensor short or wiring fault remains, the F2E4-2 error will return once the oven is powered back on. A proper repair of the shorted sensor circuit or faulty HMI assembly is required to permanently resolve the fault. Resetting without repair is not a long-term solution.

Start by unplugging the range or disconnecting power, then inspect the wiring connections at the main control board and the HMI J1 connector for loose, corroded, or damaged pins. Reseat any suspect connectors and check the harness for visible damage. If connections are intact, the HMI assembly is most likely the failed component and will need to be replaced, as the temperature sensor is integrated into that board.
