Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically from restricted airflow such as a clogged filter, closed registers, or a failing blower. Once the temperature drops back into range, the switch resets and normal heating resumes, protecting the heat exchanger from thermal stress and cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Furnace limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman VMSS960403ANAA and compatible 96% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162903 is set to the exact 150°F trip point Goodman engineered for this furnace, with the correct bracket and terminal layout.
