What it is

The Baxi 7679744 is a printed circuit board (PCB) supplied by Baxi for use in its Combi 30 appliance range. The board is the control centre of the unit, handling the electrical sequencing that governs ignition, burner modulation, pump and fan operation, and the delivery of domestic hot water and central heating. It is a direct replacement component, identified by the part number 7679744.

Signs this part needs replacing

  • The appliance fails to fire, with no ignition sequence on a call for heat or hot water.
  • The display is blank, shows a persistent fault code, or the boiler locks out repeatedly after reset.
  • Heating and hot water run intermittently, or the pump and fan do not start when demanded.
  • The board shows visible damage such as scorching, burnt tracks, swollen capacitors or corrosion from water ingress.
  • Blown fuses on the board recur after replacement, indicating a fault on the control circuit.

Before you order

  • Read the part number from the existing board and match it to 7679744 before purchase; boards for different Combi variants are not interchangeable.
  • Check the appliance data plate and any GC number to confirm the model and variant.
  • Inspect the surrounding harness, sensors and electrode leads for damage, as these can cause symptoms that mimic a failed board.

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.
