What is a Printed Circuit Board (PCB)?
A Printed Circuit Board or PCB is the 'brain' of the boiler. They control every action and can be found in most appliances from boilers to warm air units and fires. They are often referred to as a PCB, control box, mother board, driver board, sequence board, ignition board or power board. Conductive pathways are etched or "printed" onto board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits. Manufacturers Include Baxi, Ideal, Worcester, and Vaillant. We recommend that a Printed Circuit Board (PCB) is fitted by a fully qualified gas safe certified plumber.
