What Does Error F3 Mean?

The Zanussi Oven F3 error indicates a malfunction in the temperature sensor or an internal fault detected during the oven’s self-test. This can lead to erratic temperature readings, failure to heat, or the oven not reaching the set temperature. Addressing this issue may involve inspecting the temperature sensor and its wiring for faults.

Common Symptoms:

  • Oven stops heating and displays F3
  • Error appears at power‑on or during self‑test
  • Temperature may not regulate or the oven fails to reach set temperature

Possible Causes

  • Self‑diagnostic failure detected during oven self‑test (medium)
  • Temperature sensor circuit fault (open or failed sensor) (medium)

How to Fix Error F3

DIY Fix Power reset and basic check

  1. Turn off the oven at the mains power supply or unplug the unit.
  2. Wait 5–10 minutes to allow the system to fully discharge.
  3. Restore power and check if the F3 error clears.

Technician Only Inspect temperature sensor and wiring

  1. Disconnect power to the oven.
  2. Access the temperature sensor (typically at the rear of the oven cavity).
  3. Check sensor connections and wiring harness for damage or disconnection.
  4. Test sensor resistance with a multimeter and replace if open or out of expected range.
  5. After repair, reconnect and test the oven for proper operation.

Parts needed: Temperature sensor (RTD), Wiring harness, Connectors

🛑 When to Call a Pro:
  • Error persists after reset and basic checks
  • If sensor testing and wiring inspection do not resolve the issue
  • If internal control board fault is suspected
