What Does Error F02 Mean?

The Ariston oven error F02 indicates a fault in the temperature sensor (NTC), which fails to provide accurate readings. This can prevent the oven from reaching the desired temperature, often resulting in erratic display values or unusual clicking sounds during operation. If the error appears after the oven begins heating, it suggests a malfunction in either the sensor or its connection to the control board. Regular checks may resolve minor issues, but persistent errors may require sensor replacement or professional diagnosis.

Common Symptoms:

  • Oven fails to reach set temperature before error appears
  • Temperature display jumps or shows incorrect values
  • Error appears after oven begins heating

Possible Causes

  • Faulty or open/shorted cavity temperature sensor (NTC) (medium)
  • Damaged wiring harness or poor connection between NTC sensor and control board (medium)

How to Fix Error F02

DIY Fix Basic checks and reset

  1. Turn off oven and isolate power at the mains.
  2. Wait a few minutes and restore power to see if the error clears.
  3. Observe if the oven begins a normal heating cycle without showing F02.

Technician Only Inspect and replace temperature sensor

  1. Disconnect oven from mains power.
  2. Remove oven back panel and locate the cavity temperature sensor (NTC probe) inside the oven cavity.
  3. Visually inspect sensor wiring for damage, burn marks, or loose connectors.
  4. Measure sensor resistance with a multimeter at room temperature to verify within specification.
  5. Replace sensor if readings are outside spec or sensor is damaged.
  6. Reassemble and test oven heating cycles for error recurrence.

Parts needed: NTC cavity temperature sensor, multimeter for diagnostics

🛑 When to Call a Pro:
  • If sensor tests normal but F02 persists, indicating possible control board fault
  • If internal wiring damage is found that requires professional repair
