How to fix it
- Cut power at the breaker.
- Unplug the sensor connector at the rear of the cavity and measure across its pins — ~1080 ohms at room temperature is normal; near 0 ohms means replace the sensor.
- Check the sensor harness for pinch points, melted insulation, or staples through the wire.
- Replace the sensor (and any damaged section of harness) and reconnect.
- Restore power and run a 350F bake test to confirm the cavity reaches temperature.
- If F3E1 returns with a good sensor and harness, replace the electronic oven control board.
Why it happens
Typical signs: F3E1 on display · Oven won't preheat · On double ovens the code may specify the lower cavity
- Shorted oven temperature sensor Internal short in the RTD reads as zero or near-zero ohms instead of ~1080.
- Pinched or melted sensor wiring Insulation worn through against the cavity back lets the two leads touch.
- Failed control board input circuit Damaged input on the EOC can latch a sensor-short fault.
