What it is

The Baxi 720841401 is a printed circuit board (PCB) manufactured by Baxi for use in its combi boiler range. It is the control board for the RDS Combi 24 platform, handling the electrical sequencing that keeps the appliance running through a heating or hot water demand. The board sits within the boiler's control circuit and supports the safe, dependable operation of the unit.

Signs this part needs replacing

  • The boiler does not respond to a heating or hot water demand.
  • Repeated lockouts or fault codes that clear only after the power is cycled.
  • A dead or blank control display, or no response from the boiler controls.
  • The fan, pump or ignition sequence fails to start when a demand is present.
  • Operation becomes intermittent, with faults appearing and clearing unpredictably.

Before you order

  • Check the appliance GC number and, where relevant, the serial number against the compatibility list. The 124 ErP Combi listing applies to serial numbers ending AC.
  • Confirm the number printed on the existing board. The alternative number 1119904 may be marked on the board currently fitted.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
