The printed circuit board (PCB) is the electronic brain of a modern boiler or burner, controlling all electrical functions from ignition to temperature regulation. This board processes signals from sensors and sends commands to actuators, ensuring safe and efficient operation. A malfunctioning PCB can cause a wide range of issues, including failure to start, intermittent operation, or error codes. Replacing the printed circuit board is often the solution when other components test fine but the system still malfunctions. As a high-tech spare part, it is essential to choose a board that matches your equipment's specifications. Proper installation by a qualified technician is recommended to avoid damage and ensure reliable performance.
