This bimetal safety switch monitors heat-exchanger and plenum temperature and opens the circuit to the gas valve if the furnace overheats — protecting the heat exchanger from cracking due to restricted airflow, a dirty filter, or blower failure. A failed or drifted limit control is a common cause of short-cycling and no-heat lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit (auto-reset bimetal)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eFunction: Overtemperature safety shutoff\u003c\/li\u003e\n\u003cli\u003eCompatible model: AMH80803BXBD\u003c\/li\u003e\n\u003cli\u003eMounting: Furnace-specific bracket\/opening temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eUniversal limit switches require you to match trip temperature and mounting depth by hand — get it wrong and the furnace either nuisance-trips or fails to protect the heat exchanger.
