This single package includes the furnace limit switch that acts as a thermal safety cutoff for residential heating systems. You mount it directly onto blower housings and heat exchanger cabinets inside your ductwork to monitor airflow temperatures during normal operation. When your system pulls stale air or the draft motor slows down, the internal sensing element snaps open to shut off the ignition sequence. Most homeowners drop it into Trane, Carrier, and General Electric units to restore consistent warmth without calling a technician.
