Possible Causes
Blown thermal fuse or safety thermostat, failed main oven element, faulty function selector, defective main control board
How to Fix / Troubleshooting
Safety first: Turn off the oven at the mains before any internal checks.
- Confirm power: Check that the display and oven light work. If not, see the 'Oven completely dead' scenario.
- Test multiple modes: Try fan oven, conventional, and grill. If none heat, a common supply or safety device is likely open.
- Check safety thermostat: Access the top or rear of the oven and locate the thermal cut-out. Test for continuity; replace if open.
- Element tests: Test the fan oven, top, and bottom elements for continuity. Replace any open-circuit element.
- Selector and PCB: If all elements and thermostats are good, the function selector or main PCB may not be supplying power and may need replacement.
