What it is

The 93793778 is a control printed circuit board (PCB) manufactured by Valor for the AE125 Powerstar boiler range. It is the MK.2/MK.3 version of the board and governs the boiler's operating sequence and electronic control functions. It is supplied as a board assembly only.

Signs this part needs replacing

  • The boiler fails to respond to demand, with no ignition sequence or fan start.
  • Repeated lockouts that clear only after a power cycle, with no fault found elsewhere.
  • Erratic or intermittent operation of heating and hot water functions.
  • Visible damage to the board — scorching, burnt tracks, leaking capacitors or corrosion.
  • Fault codes or diagnostic indications pointing to the control board rather than a sensor or gas-side component.

Before you order

  • Confirm the boiler model is an AE125 Powerstar and identify whether the existing board is MK.2 or MK.3.
  • Read the board revision marking on the existing PCB and match it to this part number.
  • Check that the fault is not caused by a sensor, thermostat, fuse or wiring fault before replacing the board.
  • Isolate the electrical supply and follow the manufacturer's instructions for board removal and refitting.
