Jenn-Air Oven Error Code F2E4-1

F2E4-1 indicates an HMI over-temperature fault caused by an open circuit in the HMI temperature sensor. The oven's control panel assembly includes a sensor that monitors electronics temperature, and the main control board has detected that the sensor circuit has lost continuity. This can be caused by a loose connector, damaged wiring, a failed sensor, or a faulty control board.

It is best to avoid using the oven until the fault is diagnosed and cleared. The error indicates the control panel's temperature monitoring circuit is not functioning, which means the oven cannot properly protect its electronics from overheating. Continued use could risk damage to the control board or HMI assembly.

Repair costs vary depending on the cause. If the fix is simply reseating a connector, there may be no parts cost, though a service call typically runs between $75 and $150. If the HMI assembly requires replacement, parts can range from $150 to $400 or more depending on the model. Main control board replacement is generally in a similar price range, and total repair costs including labor can reach $300 to $600 in more involved cases.

In many cases, yes. Start by unplugging the range and inspecting the wiring connections at the HMI J1 connector and the main control board. Reseating a loose connector or cleaning corroded pins can resolve the fault without any parts. If the connections are secure, further diagnosis may require continuity testing of the harness or replacement of the HMI assembly, which is a more involved repair.

Disconnecting power may temporarily clear the display, but the code will return if the underlying open-circuit condition still exists. A reset alone does not repair a failed sensor, broken wire, or faulty connector. The root cause must be identified and corrected to permanently resolve the fault.
