Jenn-Air Oven Error Code F3E0-1

F3E0-1 means the control board has detected a short in the main oven temperature sensor circuit. The sensor, which monitors heat inside the oven cavity, is sending a signal that indicates an abnormally low resistance. The oven cannot operate safely without accurate temperature data, so it shuts down and displays this code. The sensor itself or its associated wiring are the most likely sources of the problem.

No, you should not attempt to use the oven while this error is active. A shorted temperature sensor means the control board cannot reliably monitor the oven's internal temperature, which creates a risk of uncontrolled overheating. Stop using the oven until the sensor circuit has been inspected and the fault has been resolved.

If only the oven temperature sensor needs replacement, parts typically range from $20 to $80 depending on the specific model, with professional labor adding $100 to $200 on top of that. If the wiring harness requires repair or replacement, costs increase moderately. A control board replacement, if needed, is the most expensive scenario and can range from $200 to $500 or more for parts and labor combined.

A knowledgeable DIYer can perform basic diagnostics such as entering diagnostics mode to check the sensor temperature reading and visually inspecting the sensor probe and wiring for obvious damage. If the sensor itself has failed, replacing the oven temperature sensor is a relatively straightforward repair on most Jenn-Air models. However, if the fault traces back to the main control board, professional repair is recommended.

Resetting the oven by cutting power at the breaker may temporarily clear the code, but it will return as soon as the control board checks the sensor circuit again. Because F3E0-1 indicates an actual hardware condition, a short in the sensor or wiring, the underlying problem must be repaired before the code will stay cleared.
