What it is

The Baxi 237730 is an electric printed circuit board (PCB) manufactured by Baxi. It is the control board that carries the appliance's electrical logic, handling the switching and monitoring duties that keep the unit running through a demand cycle. It is supplied as a direct replacement board for the Baxi appliance range it was produced for.

Signs this part needs replacing

  • The appliance shows no display, no indicator lights and does not respond when a demand is called.
  • The boiler fires briefly, locks out or cycles erratically with no consistent fault pattern.
  • Fault codes appear that point to board communication, sensor input or ignition sequencing.
  • The fan, pump or diverter does not run when the board calls for it, despite the component testing correctly.
  • Visible damage on the board itself, such as a blown fuse, scorched track or swollen capacitor.

Before you order

  • Confirm the part number printed on the existing board matches BAXI237730 or 237730 before ordering.
  • Check the appliance model and GC number against the compatibility list, as board variants can look similar but differ in software and connector layout.
  • Note the wiring and connector positions before removal so the replacement board is refitted in the same configuration.

Not sure which part?

Tell the parts assistant what it's going into — the appliance make and model, or the GC number off the data badge — and it will check this part is on the fit list.
