What Does Error F4 Mean?

The Frigidaire oven error F4 indicates a failure in the temperature sensor (RTD), which can lead to erratic temperature readings or the oven failing to heat properly. This error may cause the oven to display F4 on the control panel, and it can occur intermittently during use or preheating, indicating a short circuit or fault in the temperature sensor's circuitry.

Common Symptoms:

  • Oven displays F4 on control panel
  • Oven may fail to heat correctly or shut down preheat
  • Error may occur intermittently during use or preheat

Possible Causes

  • Shorted or faulty oven temperature sensor (RTD) (high)

How to Fix Error F4

DIY Fix Basic Checks Before Repair

  1. Turn off power to the oven by disconnecting from mains or switching off the breaker.
  2. Allow the oven to cool fully before inspecting.
  3. Visually inspect the temperature sensor’s wiring harness for signs of damage or loose connections.

Technician Only Diagnose and Repair Temperature Sensor Circuit

  1. Disconnect power to the oven and remove access panels to reach the temperature sensor (RTD).
  2. Test the sensor’s resistance with a multimeter at room temperature and compare to expected values per model specifications.
  3. Inspect wiring harness for shorts to chassis or breaks; repair or replace wiring as needed.
  4. Replace oven temperature sensor if its resistance is outside expected range or if evidence of short is found.
  5. Reassemble and restore power; verify error no longer appears.

Parts needed: Oven temperature sensor (RTD), Wiring harness, Multimeter (for diagnostics)

🛑 When to Call a Pro:
  • If the sensor wiring is inaccessible or you lack experience working with live electrical components
  • If replacing the temperature sensor and checking wiring does not clear the error
