Good To Know

Q: How does a sail switch work? A: A sail switch uses a physical vane that moves with airflow to detect low air conditions; if airflow drops, the switch opens the circuit, shutting down the furnace.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
