The Fan board is a control component used in boiler and burner systems to regulate the operation of the fan or blower. It ensures proper air supply for combustion and helps maintain efficient system performance. This board is typically part of the electrical assembly and may include connections for speed control or safety interlocks. When servicing heating equipment, replacing a faulty fan board can resolve issues with airflow and system startup.
