Mounted on the heat-exchanger bulkhead, this safety switch continuously monitors supply-air temperature. If the furnace overheats — typically from restricted airflow such as a dirty filter, closed vents, or a failing blower — the limit opens the circuit and shuts off the gas valve to protect the heat exchanger from cracking and to prevent a fire hazard. A furnace that short-cycles on heat or fails to fire may have a tripped or failed primary limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit safety cutout\u003c\/li\u003e\n\u003cli\u003eType: Auto-reset snap-disc thermostat\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMVC960804CNBA\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature.
