What it is

The Baxi 720842301 is a printed circuit board key (PCB key) set up for LPG operation, manufactured by Baxi for its Neta-Tec and Neta-Tec Plus combi boiler range. The board carries the control logic that governs ignition sequencing, fan and pump operation and the appliance's safety interlocks, and it reports fault codes back to the boiler display. Because the key is matched to the appliance's gas type, an LPG board must be used on an LPG boiler. It is supplied as a service replacement board for these combi models.

Signs this part needs replacing

  • The boiler locks out or fails to ignite, and the fault returns after a reset.
  • A blank or dead display, or the board failing to power up.
  • Erratic fan, pump or ignition behaviour that does not follow the call for heat.
  • Repeated fault codes or intermittent shutdowns during operation.
  • Visible scorching, moisture tracking or component damage on the board.

Before you order

  • Check the boiler's GC number and, where applicable, the serial number against the compatibility list before ordering.
  • Confirm the board being replaced carries part number 720842301 or the alternative number 1119906.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
