What Does Error F3 Mean?

The Frigidaire Oven F3 error indicates a malfunction in the temperature sensor, often due to an open or shorted sensor or faulty wiring. This leads to erratic temperature readings, failure to preheat, and the oven shutting down unexpectedly. It is essential to diagnose whether the issue lies with the temperature sensor, its wiring, or the control board itself.

Common Symptoms:

  • Oven displays F3 error code when heating or during preheat cycle
  • Oven fails to reach set temperature or heats unpredictably
  • Oven beeps and shuts down heating
  • Temperature readings out of expected range on multimeter for sensor

Possible Causes

  • Open or shorted oven temperature sensor (RTD) (high)
  • Damaged or loose wiring/connectors between temperature sensor and control board (high)
  • Faulty main control board sensor input circuit (medium)

How to Fix Error F3

DIY Fix Basic Checks and Reset

  1. Disconnect power to the oven (unplug or turn off breaker) for 30 seconds and restore to attempt a reset.
  2. Ensure the oven is fully cooled before attempting further inspection.

Technician Only Diagnose and Repair Temperature Sensor and Wiring

  1. Disconnect all power to the oven.
  2. Access the temperature sensor located inside the oven cavity (typically rear wall).
  3. Visually inspect wiring and connectors for damage, looseness, corrosion, or burnt spots.
  4. Use a multimeter to test the sensor’s resistance; compare to specifications.
  5. Repair or replace wiring harness if damaged or replace the temperature sensor if out of spec.
  6. Reassemble and restore power to confirm F3 is cleared.

Parts needed: Oven temperature sensor (RTD), Sensor wiring harness or connectors

Technician Only Replace Control Board if Sensor/Wiring Tests Good

  1. After verifying the sensor and wiring are functioning, test control board input circuit.
  2. Replace the main control board if diagnostics confirm board failure.
  3. Reassemble and test oven for proper operation.

Parts needed: Main control board

🛑 When to Call a Pro:
  • If you are not comfortable working with electrical components or lack tools for testing
  • If sensor and wiring pass tests yet F3 persists, indicating possible control board fault
