Jenn-Air Oven Error Code F3E1-0

F3E1-0 means the oven's secondary temperature sensor circuit is open, indicating the control board is not receiving any signal from that sensor. This prevents the oven from accurately monitoring temperature. The fault is most often caused by a failed sensor or damaged wiring in the sensor circuit.

It is not recommended to use the oven while this error is active. Because the secondary temperature sensor is not providing a valid reading, the oven may not regulate heat correctly. Continuing to operate the oven under these conditions could lead to overheating or inconsistent cooking results.

Repair costs depend on what component has failed. A replacement oven temperature sensor typically costs between $20 and $75 for the part alone. If the control board needs replacement, parts alone can range from $150 to $400 or more. Adding professional labor charges generally brings the total repair cost to somewhere between $100 and $500 depending on the diagnosis.

A knowledgeable DIYer can check for loose connectors and visually inspect the sensor wiring, which requires no special tools. However, accurately testing the sensor's resistance and diagnosing whether the control board is at fault does require a multimeter and familiarity with appliance wiring. If you are not comfortable working inside the oven cavity, a qualified technician is the safer choice.

Resetting the oven by cutting power may temporarily clear the code, but it will return as soon as the oven attempts to read the sensor again. The underlying cause, whether a failed sensor, broken wire, or bad connector, must be repaired for the code to go away permanently.
