Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and opens the circuit to the gas valve if the plenum gets too hot — typically the result of restricted airflow from a dirty filter, closed registers, or a failing blower. Once the furnace cools, this auto-reset control restores operation automatically.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine OEM Goodman \/ Amana part number 20162904\u003c\/li\u003e\n\u003cli\u003ePrimary (main) high-limit \/ auto-reset temperature control\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip and reset temperatures — no field adjustment\u003c\/li\u003e\n\u003cli\u003eDirect fit for AMS81005CXAB and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eSnap-disc design with quick-connect terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The trip temperature and disc calibration are matched to this furnace's heat exchanger and airflow design. A generic limit with the wrong set point can either trip prematurely (short-cycling and no heat) or fail to protect the heat exchanger. For proper, safe operation, the OEM control is the right choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty: Easy (2\/5).\u003c\/strong\u003e Usually two mounting screws and two spade terminals — about 15 minutes for a technician or confident DIYer.
