Reading the F3/E1 message
Kenmore 665 model ranges show their faults as an F-code followed by an E-code. F3/E1 on one of them points at the oven’s temperature sensing: either the sensor itself has gone bad, or the circuit it sits in has shorted.
Who does what
Owner: cut power by unplugging the range. If the sensor’s wire harness has worked loose, press it back onto its connector.
Technician: swaps out a harness that is damaged, reads the sensor’s resistance with a volt/ohm meter, and replaces the sensor. When both the sensor and its connections test fine, the electronic oven control (EOC) is the part that gets replaced.
Anything past reseating a loose connector means working inside the range, which makes it a technician visit.
Other sensor codes to compare
F3/E0: the open-circuit version of this same sensor fault.
F3/E2: the oven climbing past 575 degrees F in Bake mode.
F31: a shorted sensor circuit as worded on other Kenmore range series.

Model compatibility: Kenmore reuses codes across series and model years, so F3/E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
The oven temperature sensor is defective or its circuit is shorted.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
