What it is

The Baxi 5112380 is a printed circuit board (PCB) used to control the operating sequence of a range of Baxi, Main and Potterton gas boilers. It carries the boiler's control logic and switching, handling ignition sequencing, fan and pump control, temperature regulation and safety lockout. The board is supplied as a direct replacement for the original item fitted to the Combi and System models listed below.

Signs this part needs replacing

  • Boiler fails to fire or locks out with no fault code shown on the display
  • No heating or no hot water, with the pump or fan not running
  • Erratic behaviour such as the boiler cycling on and off without demand
  • Visible scorching, burn marks or a blown track on the board
  • Repeated lockouts that clear temporarily after a power reset

Before you order

  • Check the GC number on the appliance data badge against the list above, as the same part number covers several Combi and System variants
  • Confirm the boiler model and control version before ordering, since board layout differs between Combi and System appliances
  • Isolate the electrical supply to the boiler before removing or fitting the board
  • Inspect the wiring harness and plug connections for heat damage while the board is out

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.
