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

  1. Turn off power.
  2. Remove sensor and measure resistance at room temp (should be ~1090 ohms).
  3. Compare to spec (varies by model).
  4. 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.
