Possible Causes
Tripped circuit breaker, Loose power cord connection, Burned terminal block, Blown internal fuse on control board, Failed main control board
How to Fix / Troubleshooting
Safety first: Turn off the breaker before inspecting the rear of the range. High voltage is present at the terminal block.
- Check breaker: Verify the range breaker is not tripped. Reset if necessary.
- Inspect power cord and outlet: Ensure the cord is plugged in securely and the outlet has correct voltage.
- Check terminal block: Remove the rear cover and inspect the terminal block for burnt wires or melted plastic. Repair or replace as needed.
- Internal fuse: Some Blomberg models have an internal fuse on the control board. Check and replace with the exact type if blown, but investigate the cause of the failure.
- Replace control board: If power is present at the board but it remains dead, replace the main control/EOC.
