Kenmore Wall Oven F3 Error Code

F3 on a Kenmore wall oven is an oven temperature sensor failure. It applies to Kenmore manual-cleaning wall ovens with model numbers starting 790, and to Kenmore and Kenmore Elite self-cleaning wall ovens with model numbers starting 790.

What you can do first

Unplug the wall oven before anything else. The remaining checks in the manual use a multimeter, so they belong to a technician.

What a technician checks

• Resistance through the oven temperature sensor circuit, measured from the electronic oven control board. Around 1,080 ohms at room temperature is expected.
• If that reading is off, resistance measured directly at the sensor decides whether the sensor itself is replaced.
• With a good sensor reading, a damaged wire harness is the next replacement.
• With correct resistance through the sensor wires, the electronic oven control board is replaced because it is not reading the sensor accurately.

Sensor codes with an E number

Ovens that show pairs such as F3/E0 or F3/E1 report whether the sensor circuit is open or shorted. F3/E2 is the over-temperature reading in Bake mode.
