Error codeF3
ApplianceWall Oven
An oven temperature sensor failure is what F3 stands for on a Kenmore wall oven. The listing covers manual-cleaning Kenmore wall ovens with model numbers starting 790, as well as Kenmore and Kenmore Elite self-cleaning wall ovens in that 790 range.
Owner action
Unplug the oven first. Everything beyond that in the manual relies on a multimeter, which makes it technician work.
The technician’s sequence
Measure resistance through the sensor circuit at the electronic oven control board. At room temperature, roughly 1,080 ohms is the expected figure.
A reading more than 200 ohms away from that sends the technician to measure directly at the sensor, and the sensor is replaced.
When the sensor itself reads correctly, the wire harness is replaced.
If resistance through the sensor wiring is right but the board-side reading is not, the electronic oven control board is replaced, since it is not reading the sensor properly.
Sensor codes carrying an E number
Pairs such as F3/E0 (open circuit) and F3/E1 (shorted circuit) split the sensor fault into two types, while F3/E2 is an over-temperature in Bake mode.
Kenmore wall oven repair in San Francisco
With F3 on the display, leave the multimeter work to Kenmore wall oven repair. From San Francisco or elsewhere in the Bay Area, ring (415) 825-6393 and read out the 790 model number and the code, and say that the oven has been unplugged.
Model compatibility: Kenmore reuses codes across series and model years, so F3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
