How to Fix / Troubleshooting
Safety: Turn off power at the breaker before opening any panels.
- Confirm mains: Check that the circuit breaker is on and that other functions (like oven light) operate.
- Inspect terminal block: Ensure mains connections are tight and not burnt.
- Check internal fuse: Locate any fuses on the main control board or separate power module and test for continuity. Replace only with identical type and rating.
- Check UI connections: Reseat the connectors between the main board and the display/UI board.
Note: If fuses blow again immediately or the power supply section is visibly damaged, the control board must be replaced by a professional.
