Jenn-Air Oven Error Code F2E5-4

F2E5-4 indicates that the HMI 1 control module has detected a fault with the Secondary Cavity Camera function. The camera feature, which allows you to view the oven interior from the control panel or a connected device, is not operating correctly through the HMI. This fault points to a problem in the camera hardware, wiring connections, or the HMI board itself.

This fault relates specifically to the camera viewing feature and does not indicate a problem with the oven's heating or cooking functions. The oven should still be able to operate for baking and broiling. However, if you are unsure of the oven's overall status, discontinue use until the fault has been diagnosed.

Repair costs depend on which component has failed. Reseating a loose connector may involve only a service call fee, typically in the range of $75 to $150. Replacing a wiring harness or camera module can bring total costs to somewhere between $150 and $350 or more depending on parts and labor. An HMI board replacement tends to be the most expensive scenario, often ranging from $250 to $500 or higher depending on the specific model.

Start by unplugging the oven or shutting off the circuit breaker, then inspect all wiring connections between the camera and the main control board and HMI. Reseat any loose connectors and look for visible wire damage. If connections are secure and undamaged, further diagnosis will involve testing the camera module and HMI board, which typically requires a qualified technician.

Disconnecting power and restoring it may temporarily clear the error code, but the fault will return if the underlying cause has not been addressed. If the camera hardware, wiring, or HMI board has a genuine defect, the code will reappear during normal operation. A reset is a useful first step to confirm the issue is persistent, but it is not a repair.
