F33Warning
KitchenAid Oven/Range F33 Error Code
The oven temperature sensor is reading an invalid resistance value.
Common causes
- Sensor drifted out of calibration
- Faulty sensor
- Loose connection
How to fix it
- Turn off power.
- Remove sensor and measure resistance at room temp (should be ~1090 ohms).
- Compare to spec (varies by model).
- If resistance is off by more than 10%, replace the sensor.
⚠ When to call a pro: If sensor tests correctly, the control board may be misreading; call a technician.
