Kenmore Range Error Code F3-E1

F3-E1 on a Kenmore range indicates a short circuit in the oven temperature sensor circuit. The control board has detected an abnormally low resistance reading from the sensor circuit, which prevents the oven from accurately measuring temperature. The fault can originate at the sensor itself, the wiring harness, the terminal connections, or in some cases the control board.

It is not recommended to use the oven when F3-E1 is active. Because the control board cannot reliably read the oven temperature, it cannot regulate heating accurately, which creates a risk of overheating. The oven should remain unused until the sensor circuit fault is diagnosed and corrected.

You can clear the F3-E1 code using the manual diagnostics screen on the control board, and a power reset may temporarily clear the display. However, if the underlying short in the sensor circuit has not been repaired, the fault will return as soon as the control board re-checks the sensor circuit. Clearing the code without fixing the root cause does not resolve the problem.

A knowledgeable DIYer can diagnose this fault by accessing the oven sensor, disconnecting it, and using a multimeter to measure resistance across the sensor terminals and from each terminal to the oven casing. If the sensor reads near zero ohms or shows a short to ground, replacing the sensor is a straightforward repair. Harness damage can also be repaired or replaced with basic tools, but if the control board is the cause, that repair is more involved.

If only the oven temperature sensor needs replacement, parts typically cost between $20 and $60 depending on the model, and the repair is relatively inexpensive. A wiring harness replacement can range from $30 to $80 for parts. If the control board is at fault, parts alone can range from $100 to $300 or more, and professional labor will add to that cost.
