The main printed circuit board (PCB) is the brain of modern boiler and burner systems, controlling ignition, temperature, safety functions, and more. When this board fails, the entire system may stop working or behave erratically. Replacing a defective main PCB with a compatible unit is essential to restore full functionality. Ensure the replacement matches your system's specifications for proper communication with other components.
