Amana Oven/Range F3 Error Code
The oven temperature sensor circuit is open, so the oven cannot accurately measure temperature.
Common causes
- Faulty oven temperature sensor (RTD probe)
- Loose or broken wire connection to sensor
- Damaged wiring harness
How to fix it
- Unplug oven or turn off breaker.
- Remove the oven temperature sensor (located inside oven back wall).
- Measure resistance with multimeter at room temp (should be ~1090 ohms).
- If open or out of spec, replace sensor.
⚠ When to call a pro: If sensor tests good and wiring checks out, call a pro for control board diagnosis.
