Baxi Control and Display PCB 130HE 5109761

The Baxi 5109761 is a control and display printed circuit board kit manufactured by Baxi for its Combi 130HE appliance. The board carries the boiler's electronic control circuitry together with the display interface that reports operating status and fault information at the fascia. It is supplied as a kit so the control and display functions are replaced together as one assembly.

• The display panel is blank, dark or shows only partial segments while the boiler is powered.
• The boiler does not respond to a call for heating or hot water, or the controls have no effect.
• Fault codes appear repeatedly and clear only after the power supply is cycled.
• The appliance locks out intermittently with no other obvious cause.
• Buttons on the control fascia fail to register presses.

• Confirm the appliance model and GC number against the compatibility list; the GC number is shown on the appliance data badge.
• Compare the board being removed with the alternative part numbers listed below to make sure the correct variant is supplied.
• Inspect any seals disturbed during access and replace them if they are damaged.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
