Mounted to the heat-exchanger vestibule, it monitors supply-air temperature and cuts the gas valve if airflow is lost or restricted (dirty filter, failed blower, closed registers), protecting the heat exchanger from overheating. It automatically resets once temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit switch, auto-reset\u003c\/li\u003e\n\u003cli\u003eTrip point: 150°F (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eCircuit: Normally closed\u003c\/li\u003e\n\u003cli\u003eFit: Goodman \u0026amp; Amana gas furnaces incl.

This genuine OEM switch matches your furnace's designed limit exactly. A generic switch with a different setpoint or mounting bracket can cause nuisance lockouts or fail to protect the heat exchanger — not worth the risk on a safety device.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Usually two screws and two spade terminals.
