Error codeF3/E3
ApplianceWall Oven
When Clean mode runs too hot
Once CLEAN mode drives the cavity past 950 degrees F, a Kenmore 665 model wall oven puts F3/E3 on the display.
Owner steps
Begin by cutting power to the oven at the switch or the plug.
Inspect the oven temperature sensor wire and push it back on if it has worked loose.
Fit a fresh harness when the wire harness shows damage.
Resistance test and parts
Meter in hand, the technician tests the temperature sensor. Any value but 1080 ohms at 70 degrees F (room temperature) ends with a new sensor. Good readings and sound connections shift the blame to the electronic oven control (EOC).
Compare with these codes
F3/E2 is the Bake mode version of this overheating reading. F3/E0 points to an open sensor circuit.
Wall oven repair, San Francisco and Bay Area
To have F3/E3 looked at, book Kenmore wall oven repair by phoning (415) 825-6393. A written note of the code, your oven model number and what you tried makes the conversation short.
Model compatibility: Kenmore reuses codes across series and model years, so F3/E3 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/E3 means the oven temperature exceeded 950 F in Clean mode.
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.
