What it is

The Ideal 171104 is a printed circuit board (PCB), designated MB1 and carrying the board reference 8805-5598. It is the main control board for Ideal Commercial combi appliances, handling ignition sequencing, fan and gas valve control, temperature regulation and the safety interlocks that shut the appliance down on a fault. The board is supplied as a complete assembly for direct replacement of the original unit.

Signs this part needs replacing

  • The display is blank, flickering or showing persistent error codes that return after a reset.
  • The fan or pump runs continuously when there is no call for heat.
  • The appliance behaves erratically, with intermittent heating or hot water delivery.
