What it is

The BI1955100 is a Biasi electronic control and ignition printed circuit board used in the Garda M110B.24 and RIVA Advance HE M110B.24 gas boiler families. It manages boiler sequencing and provides the ignition control function within the appliance. The board is supplied as a printed circuit board spare for the models listed below.

Signs this part needs replacing

  • The boiler fails to ignite, with no spark at the electrode during a call for heat.
  • The appliance locks out repeatedly and requires resetting to restore operation.
  • Ignition is intermittent, with the boiler firing on some attempts and not others.
  • The boiler starts but shuts down shortly after, suggesting a loss of flame supervision or control signal.
  • Visible damage to the board, such as scorching, burnt tracks or swollen components.

Before you order

  • Confirm your boiler model against the fit list above, as the board is specific to these M110B.24 variants.
  • Check the part number printed on the existing board matches BI1955100 before ordering.
  • Verify the appliance's GC number against the boiler data badge to confirm the correct variant.
  • If the boiler is under warranty, check with the manufacturer before carrying out the repair.
