Mounted on the heat-exchanger\/blower deck, it monitors supply-air temperature and shuts down the burners if the furnace overheats due to restricted airflow — protecting the heat exchanger from cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003ePart Type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (opens on high temp, recloses when cooled)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMVC800805DNAA (Amana 80% AFUE variable-speed furnace)\u003c\/li\u003e\n\u003cli\u003eFunction: Normally-closed thermal limit, factory-calibrated trip point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e carries the exact trip and reset temperatures matched to this furnace's heat-exchanger design and blower deck. Generic limit controls with a different set point or probe length can nuisance-trip on normal cycles or fail to protect the heat exchanger. Because this guards against heat-exchanger failure and CO exposure, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Shut off power, remove the blower-compartment panel, unplug the wiring harness, remove the two mounting screws, and transfer the new control. 20–30 minutes. Frequent tripping usually indicates a dirty filter, closed registers, or a failing blower — diagnose the airflow cause, don't just replace the switch.\u003c\/p\u003e\u003cp\u003eGenuine Goodman\/Amana part.
