Mounted on the heat exchanger or plenum, this normally-closed switch monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard when airflow is restricted by a dirty filter or blower fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (open on rise)\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit \/ auto-reset safety switch\u003c\/li\u003e\n\u003cli\u003eFits Model: AMEH800805CXAA\u003c\/li\u003e\n\u003cli\u003eFunction: Cuts burner operation on high plenum temperature\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eGenuine OEM 20162903\u003c\/strong\u003e is calibrated to the exact 150°F trip point and mounting geometry the AMEH furnace requires. Generic limit switches with the wrong temperature rating or bracket can trip too early (short-cycling, no heat) or too late (overheating risk). For a safety-critical control, OEM is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003e2 of 5\u003c\/strong\u003e.
