Additional Product Information
How The Sail Switch Works: The sail switch works by sensing the airflow. If there is an insufficient amount, the switch will prevent the furnace from igniting and the fan will be running but you will get no heat. It typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it.
