The switch monitors supply-air temperature and opens the control circuit when the preset trip point is reached, shutting down the burner to prevent heat exchanger damage. This is a genuine OEM replacement part intended for licensed HVAC technicians performing component-level furnace repairs. It restores proper high-limit protection in systems where the original switch has failed an open or shorted condition.\u003c\/p\u003e\n\u003cp\u003eThis primary limit switch is designed for use in residential and light-commercial gas furnace applications. It installs in the furnace cabinet where airflow across the heat exchanger is monitored. A failed or nuisance-tripping limit switch is a common service call item, and replacing it with an OEM-spec part ensures the control board sees accurate thermal protection signals.
