I have a vaillant VCWGB 242EH Bolier - There is no power to the fan. I have 3 circuit boards but dont know which one is which. Does anyone have a diagram of the circuit boards or can anyone tell me which one is the ignition board.

The fan is good and all the fuses are ok. Thank-you for your help and assistance. Terry

The PCB with a black control mounted to / jutting out from the left hand side is listed as the flame supervision device (ignition).
Hope this helps
