Mounted on the heat-exchanger plenum, this 150°F auto-reset control opens the gas circuit if supply-air temperature climbs too high — the classic protection against a stuck blower, dirty filter, or restricted ductwork. A failed limit switch causes no-heat lockouts or dangerous overheating, so a genuine spec-matched replacement is essential.\u003c\/p\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 Temperature:\u003c\/strong\u003e 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Dual spade connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Plenum \/ heat-exchanger bracket (direct fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMH80805CNBD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM limit switches are calibrated to Goodman's exact 150°F trip point and insertion depth.
