This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

Possible Causes

Blown low‑voltage fuse on control board, Failed internal transformer or SMPS, Loose connector feeding control board, Broken track on PCB

Safety first: Isolate the oven from mains before opening the control area.

Check supply to board: Verify that mains voltage reaches the control board input terminals.
Inspect onboard fuse: Look for a small fuse on the control PCB. Test and replace with identical rating if blown, but investigate for shorts first.
Connector check: Ensure the harness from the terminal block to the control board is firmly connected.
Board replacement: If the board receives mains but remains dead, replace the main control board.
