Mounted on the heat exchanger bulkhead, it continuously monitors supply-air temperature and shuts off the gas valve if the furnace overheats due to a dirty filter, closed registers, or a failing blower — 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\u003eType: Primary auto-reset high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed (opens on overtemp)\u003c\/li\u003e\n\u003cli\u003eEquipment: High-efficiency gas furnace\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMVC960403BNAA and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e primary limit is factory-calibrated to the trip and reset temperatures specified for the AMVC960 heat exchanger.
