Jenn-Air Oven Error Code F3E0-0

F3E0-0 means the control board has detected an open circuit in the main oven temperature sensor. This tells the oven that it cannot read the cavity temperature, which prevents it from operating safely. The fault points to the sensor itself, the wiring connecting it to the board, or the connector terminals in that circuit.

No, you should not attempt to use the oven while this error is active. Because the control board cannot read the oven temperature, it has no way to regulate or limit the heat produced by the bake or broil elements. Continuing to operate the oven in this condition creates a risk of overheating.

If only the temperature sensor needs replacement, parts typically range from $20 to $80 depending on the model, and the total repair cost including labor from a technician usually falls between $100 and $250. If the control board is at fault, parts and labor costs can range from $200 to $450 or more. Diagnosing the fault before ordering parts helps avoid unnecessary expenses.

A knowledgeable DIYer can often resolve this fault by entering diagnostics mode to check the sensor reading, then inspecting the wiring and connectors for visible damage or loose connections. Replacing the oven temperature sensor is a straightforward repair that requires basic tools and a compatible replacement part. If the wiring harness or control board is involved, a technician may be needed for a more involved repair.

A power reset, such as unplugging the oven or tripping the circuit breaker for a minute, may temporarily clear the code. However, if the underlying fault in the sensor circuit is still present, the error will return as soon as the oven attempts to operate. A reset alone does not fix the problem and should not be used as a substitute for diagnosing the root cause.
