The Control Board (PCB) on Your Laars 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 Laars systems — including models such as Mascot FT, Mascot HT, NeoTherm — a failing control board (pcb) often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Laars part.
