What it is

The Baxi 720842601 is a printed circuit board (PCB) used to control the operating sequence of the appliance. It manages ignition, fan operation, gas valve sequencing and the safety interlocks that sit behind them, and it reports faults back through the boiler's status or fault display. This board is specified for the RDS Combi 28 LPG platform and the related Neta-Tec combi range.

Signs this part needs replacing

  • The boiler shows no display or fails to power up when demand is called.
  • Repeated lockouts or fault codes that clear and then return shortly after reset.
  • The fan, pump or gas valve does not respond to a call for heat.
  • Ignition sequence starts but the burner does not light, or lights and drops out.
  • Erratic behaviour that changes with temperature or after the board has been running for a while.

Before you order

  • Check the appliance GC number and model against the compatibility list, as several Neta-Tec variants use different boards.
  • Confirm the board currently fitted carries the number 720842601 or the alternative number 1119946 before ordering.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
