Mounted on the heat-exchanger bulkhead, it continuously senses plenum temperature and opens the gas\/ignition circuit whenever the furnace exceeds its safe operating limit — protecting the heat exchanger, blower, and ductwork from heat damage caused by low airflow. This auto-reset control closes again once temperatures return to normal, allowing the furnace to resume heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary limit \/ high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (temperature-sensing snap disc)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature cutout for the primary heating circuit\u003c\/li\u003e\n\u003cli\u003eMounting: Factory bracket \/ plenum mount\u003c\/li\u003e\n\u003cli\u003eFits: Goodman VMSS960803BNAA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAs the furnace's primary over-temperature protection, this control must trip at the precise factory-calibrated setpoint.
