Error codeF3/E0
ApplianceRange
What the code says
F3/E0 tells a 665 series Kenmore owner that the sensor reading oven heat has gone bad, or that the wiring loop to it is open.
Manual checklist
Cut power or pull the plug.
A loose plug on the sensor’s harness gets pushed home.
A harness that is damaged is replaced.
Beyond the harness
Next a meter reads the sensor’s resistance, and a bad reading means a new sensor. When sensor and plugs both check out, the electronic oven control is what remains to be replaced. All of this is technician work.
Related Kenmore range codes
F3 covers the same sensor fault on 362 and 790 ranges.
F2/E0 is a keypad harness message on the same series.
Kenmore range service in the San Francisco Bay Area
Sensor circuit testing on a Kenmore oven is part of Kenmore range repair for San Francisco homes. Dial (415) 825-6393 with the 665 model number, the F3/E0 display and a mention of any harness plug you pushed back in.
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 is a defective oven temperature sensor or an open oven temperature sensor circuit on the Kenmore 665 model range.
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.
