This normally-closed safety control monitors heat-exchanger and plenum temperature, opening the circuit to shut off the gas valve and burners if temperature exceeds its 150°F trip point. It is a critical safety component — a failed or out-of-spec limit switch is a common cause of short-cycling, no-heat calls, and lockout faults.\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, normally closed\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\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMH950905DXAC and select 95% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a genuine OEM Goodman component with the exact trip temperature, bracket geometry, and mounting hole pattern the furnace was designed around.
