This safety switch continuously monitors heat-exchanger discharge temperature and shuts off the gas valve and burners if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions. A failed limit control is one of the most common causes of a furnace that ignites and then short-cycles or locks out on a safety fault.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Primary high-limit \/ temperature cutout\u003c\/li\u003e\n\u003cli\u003eType: Snap-disc bimetal automatic-reset limit\u003c\/li\u003e\n\u003cli\u003eMounting: Bracket-mount to furnace vestibule panel\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace (modulating \/ variable-speed)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana ACVM970803BNAA and compatible 97% AFUE models\u003c\/li\u003e\n\u003cli\u003eOEM Part No.: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e ships with the factory-calibrated trip temperature matched exactly to the ACVM heat-exchanger design, guaranteeing correct safety cutoff and preserving your equipment warranty.
