What it is

The Baxi PCB/RDS key, part number 720844401, is an electronic control component used on Baxi Duo-tec 2 Combi 24 GA boilers. It forms part of the appliance's control and diagnostic circuit, and is supplied in an LPG specification. It is fitted to the boiler as a serviceable control part.

Signs this part needs replacing

  • The boiler fails to fire or will not run through its ignition sequence.
  • The appliance locks out repeatedly and requires resetting.
  • No display, blank display or erratic display behaviour on the control panel.
  • Fault codes relating to the control board are logged.
  • Intermittent operation, with the boiler cutting out without an obvious external cause.

Before you order

  • Confirm the boiler model is a Duo-tec 2 Combi 24 GA and check the GC number on the appliance data badge.
  • Confirm the gas type of the installation, as this part is the LPG specification.
  • Check the part number on the existing control component against 720844401 before ordering.
  • Isolate the electrical supply to the appliance before any work is carried out.
