What Does Error F3 Mean?

The Hotpoint Oven F3 error indicates a malfunction in the temperature sensor, resulting in inaccurate temperature readings and potential failure to heat. This issue is typically caused by an open or shorted temperature sensor circuit, damaged wiring, or, less commonly, a misinterpreted error by the control board.

Common Symptoms:

  • Oven fails to heat properly
  • Oven displays F3 and shuts down
  • Inaccurate or wildly fluctuating temperature

Possible Causes

  • Open or shorted oven temperature sensor (RTD) circuit (medium)
  • Loose/damaged wiring between sensor and control board (medium)
  • Electronic control board may misinterpret open circuit (rare) (low)

How to Fix Error F3

DIY Fix Basic user-level checks

  1. Turn off power to the oven at the breaker or unplug.
  2. Visually inspect the oven temperature sensor (rear of oven cavity) and visible wires for obvious damage or disconnection.
  3. Ensure sensor isn’t touching oven wall and that connections appear seated.
  4. Restore power and see if error persists.

Technician Only Technician-level diagnosis and repair

  1. Disconnect power and access the oven temperature sensor assembly.
  2. Test the temperature sensor’s resistance with a multimeter to verify it’s within expected range (typically ~1100 ohms at room temperature, model dependent).
  3. Inspect and test continuity of wiring harness from sensor to control board.
  4. Replace faulty temperature sensor if test fails.
  5. If sensor and wiring are good but error persists, test and potentially replace the electronic control board input circuitry.

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

🛑 When to Call a Pro:
  • If you cannot safely access components or do not have the tools/experience to test electrical circuits
  • If after testing sensor and wiring the error persists indicating possible control board issue
