Possible Causes
Tripped internal thermal fuse, Blown line fuse on control board, Loose wiring to control, Failed electronic oven control board
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing internal components. Verify power is off with a non-contact voltage tester.
- Check breaker and supply: Confirm the oven’s breaker is ON and that 240V (or 120V for some models) is present at the terminal block.
- Access control area: Remove the back panel or control panel cover to expose the electronic oven control and wiring.
- Inspect fuses: Look for an inline thermal fuse or small glass/ceramic fuse on or near the control board. Test for continuity; replace any open thermal fuse or line fuse with the exact type and rating.
- Check wiring and board: Ensure all connectors are seated and there are no burned traces on the control board. If fuses and wiring are good but the display remains dead, replace the electronic oven control board.
If a thermal fuse has blown, investigate possible overheating causes (blocked vents, failed cooling fan) before restoring operation.
