What Does Error F03 Mean?

The DeLonghi oven error F03 signifies a malfunction in the temperature sensor, resulting in inaccurate temperature readings and the oven's inability to reach or maintain the set temperature. This error may occur during preheating or while attempting to heat. It's often linked to a failure in the heating circuit, which includes the temperature sensor and heating elements. Addressing this issue typically requires inspection and potential replacement of these components to restore proper functionality.

Common Symptoms:

  • Error F03 shown during preheating or when attempting to heat
  • Oven fails to reach or maintain set temperature

Possible Causes

  • Heating circuit failure – likely related to temperature sensor or heating components (medium)

How to Fix Error F03

DIY Fix Basic checks and reset

  1. Turn off the oven and disconnect power at the breaker or plug for a few minutes and then restore power.
  2. Verify oven settings and ensure preheat is used properly.
  3. Observe if error reappears after reset.

Technician Only Inspect and test temperature sensor and heating elements

  1. Disconnect oven from power.
  2. Access internal temperature sensor (probe) and inspect wiring connections for continuity.
  3. Test sensor resistance with a multimeter and compare to expected values.
  4. Inspect heating elements for breakage or damage and test continuity.
  5. Replace temperature sensor or heating element if out of specification.

Parts needed: Temperature sensor (NTC or equivalent), Heating element(s)

🛑 When to Call a Pro:
