The signal/reset board is an electronic control component that manages boiler operations and safety functions. It processes signals from sensors and allows for manual reset after faults. This board is essential for regulating ignition, flame detection, and temperature control. A faulty signal/reset board can cause system shutdowns or erratic behavior. Replacing it with a compatible board ensures your boiler operates reliably and safely, restoring proper communication between components.
