Reading F3/E1
For owners of a Kenmore 665 model wall oven, these characters point at the oven temperature sensor: either the sensor is defective, or its circuit has shorted.
Parts and checks in order
Remove power by switching off or unplugging the oven.
Press a loose sensor wire harness connection back together.
Replace the harness when it is damaged.
Technician step: a volt/ohm meter reading the sensor at 70 degrees F. If it is not 1080 ohms, a new sensor goes in.
With sensor and harness connections sound, the electronic oven control (EOC) is the replacement.
Where this code sits among its neighbours
The open-circuit counterpart is F3/E0. A temperature over the limit in Clean mode is F3/E3, and the plain F3 is the general sensor failure code on the 790 models.
Kenmore wall oven help in the Bay Area
San Francisco households can arrange Kenmore wall oven repair by calling (415) 825-6393. Before dialling, jot down F3/E1, the oven’s model number and anything you did to the sensor harness.
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.
Plain language
What this code means
F3/E1 means a defective oven temperature sensor or a shorted sensor circuit.
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.
