Why Replace the Sail Switch?

A failing sail switch is a common cause of furnace problems. This part ensures the blower is moving enough air before gas ignition occurs. If the switch becomes dirty, damaged, or misaligned, the furnace may:

• Fail to ignite
• Shut down shortly after startup
• Blow cold air only
• Lock out for safety reasons

Replacing it restores proper operation and safe performance.
