What Does Error F3 Mean?

The Kelvinator Oven F3 error code signals an open oven temperature sensor (RTD) fault. This means the control board has detected a broken or disconnected sensor circuit, leading to improper heating or erratic temperature readings. Users may notice the F3 code displayed on the control panel, along with symptoms like uneven cooking or the oven not heating at all. Troubleshooting can begin with a visual inspection of the sensor and its wiring.

Common Symptoms:

  • F3 code displayed on the oven control panel
  • Oven fails to heat properly or at all
  • Temperature regulation errors or uneven cooking

Possible Causes

  • Open or failed oven temperature sensor (RTD) (medium)
  • Loose or disconnected sensor harness or wiring between the temperature sensor and control board (medium)

How to Fix Error F3

DIY Fix Initial checks and safe reset

  1. Power off and unplug the oven or turn off its circuit breaker
  2. Visually inspect the oven temperature sensor harness connection at the sensor and control board (ensure power is off)
  3. Check for obvious wiring disconnections or loose plugs
  4. Restore power and check if F3 reappears

Technician Only Sensor and wiring diagnosis and replacement

  1. Disconnect oven from power.
  2. Locate the oven temperature sensor.
  3. Test the sensor’s continuity with a multimeter; replace if open or outside spec.
  4. Inspect and test wiring harness continuity between sensor and control board; repair or replace as needed.
  5. Reassemble and test oven operation.

Parts needed: Oven temperature sensor (RTD), Wiring harness/connectors

🛑 When to Call a Pro:
  • If replacement of sensor or wiring does not clear F3
  • If testing reveals control board faults or further electrical issues
