How to Fix / Troubleshooting
Safety first: This involves high voltage. Turn off the breaker before opening any panels. If unsure, contact a qualified electrician or technician.
- Check breaker: Verify the oven's circuit breaker is not tripped. Reset if necessary.
- Verify outlet/junction: Confirm that the wall outlet or junction box is supplying power (use a multimeter if qualified).
- Inspect terminal block: With power OFF, remove the rear cover and check for loose or burned wires at the terminal block. Tighten or replace as needed.
- Internal fuse: Some Thermador ovens have internal fuses on the power input. Test and replace any blown fuses with the exact type and rating.
- Control board: If power is present at the terminal block but the display is dead, the EOC or power supply board is likely faulty and should be replaced.
