F3E2 — Oven Temperature Sensor (RTD) Fault
F3E2 indicates a problem with the oven temperature sensor (RTD) or its wiring — open, shorted, or out of range. It is not an over-temperature condition (that is a different F3-family code). Test the sensor (~1080 ohms at room temperature) and its harness.

How to fix it
- Cut power immediately at the breaker.
- Inspect the bake and broil elements — if they remain powered with the control off, a relay is welded.
- Test the temperature sensor (should read ~1080 ohms at room temp).
- Replace the control/relay board if a relay is stuck.
- Replace the sensor if it reads out of spec.
- Do not run the oven until the cause is fixed — risk of fire.
Why it happens

- Welded bake/broil relay Relay on the control board stuck closed, leaving the element powered.
- Failed temperature sensor Sensor drifting low so control over-fires the element.
- Door latch / self-clean fault Self-clean cycle ran with bad temperature data.
