Possible Causes
Tripped circuit breaker or blown fuse, Faulty power cord, Loose connection at terminal block, Failed main control board power supply section
How to Fix / Troubleshooting
Safety: Turn off the breaker before inspecting wiring. Only perform checks you are comfortable with; mains voltage is dangerous.
Steps:
- 1. Check household power: Verify the outlet has power by plugging in another device. Reset any tripped breakers or replace blown fuses.
- 2. Inspect power cord: Look for cuts, kinks, or burn marks. Replace the cord if damaged.
- 3. Check terminal block (if hardwired): Remove the cover and ensure all wires are tight and not burnt.
- 4. Test outlet voltage: Use a multimeter to confirm correct voltage at the outlet or junction box.
- 5. Inspect main control board: If power is present at the input but the unit is dead, the board’s power supply may have failed. Look for burnt components and replace the board if necessary.
Note: If you are not trained to work with live circuits, contact an electrician or authorized Gaggenau service technician.
