The Control Board (PCB) on Your John Wood Boiler

The control board (PCB) manages ignition, modulation, pump and valve control, sensors, and safety logic. A failed board causes erratic behaviour, blank displays, communication errors, or a completely dead boiler.

On John Wood systems — including models such as Envirosense, JW Power Vent, JW Direct Vent — a failing control board (pcb) often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine John Wood part.
