Checks you can try yourself

  1. Confirm the clock/timer is set correctly. Some ovens will not heat if the timer is in an auto mode.
  2. Try different functions (bake, fan, grill) to see which elements still work.
  3. Visually inspect the main oven element for blisters, cracks or obvious breaks.
  4. If only the fan runs, the heating element circuit is likely at fault.

Always unplug the appliance and switch off the power at the mains before accessing internal parts, and do not work on gas appliances yourself.

Advanced checks

  • With the power isolated, a competent person can test the element for continuity with a multimeter.
  • If multiple functions fail, the problem may be with the selector switch or control board.

How to prevent this problem

  • Avoid slamming the door and keep the door seal clean so heat stays inside the cavity.
  • Do not run the oven with badly warped trays that can touch elements or sensors.
  • Use a gentle cleaner for the interior and avoid spraying directly onto elements or thermostats.

When to call a professional

If you are not comfortable working around mains wiring or if the element tests open circuit, arrange for an appliance engineer to replace the faulty parts safely.
