Error codeF3/E0
ApplianceWall Oven
Open circuit in the temperature sensor wiring, or a bad sensor outright: that is the meaning of F3/E0 on a Kenmore 665 model wall oven.
What the owner can try
Switch off power to the oven or pull its plug.
Push the oven temperature sensor wire harness connection firmly home if it is loose.
Swap the wire harness out when it looks damaged.
Meter work for a technician
Using a volt/ohm meter, the technician reads the sensor at room temperature (70 degrees F). Anything other than 1080 ohms condemns the sensor. A sensor and harness that both check out move the replacement to the electronic oven control (EOC).
Close relatives of this code
F3/E1: the same sensor, but with a shorted circuit.
A technician visit is the next step when F3/E0 stays after the harness is reseated. Request Kenmore wall oven repair for San Francisco and Bay Area homes at (415) 825-6393, quoting the code, your model number and whether the harness connection turned out loose.
Model compatibility: Kenmore reuses codes across series and model years, so F3/E0 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/E0 means a defective oven temperature sensor or an open 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.
