A boiler PCB controls how the boiler runs. It manages ignition, sensors, pumps, fan, and safety checks. If the PCB fails, the boiler can lock out often. You may see random fault codes or a dead display. Heating or hot water may stop without warning. Replace the correct PCB's to restore stable boiler operation and proper control.
