Mounted on the heat-exchanger bulkhead, the primary limit continuously monitors supply-air\/heat-exchanger temperature. If airflow is restricted — a dirty filter, failing blower, or closed registers — it opens to shut off the gas valve and prevent the heat exchanger from overheating, then automatically resets once temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eFunction: De-energizes gas valve on high heat-exchanger temperature\u003c\/li\u003e\n\u003cli\u003eMounting: Bulkhead\/plate mount at heat exchanger\u003c\/li\u003e\n\u003cli\u003eFit: AMVC80804CNBC and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is factory-calibrated to the exact cut-out temperature and sensing-element length for this furnace. Generic limits with a different trip point or probe geometry can nuisance-trip or, worse, fail to protect the heat exchanger.

Confirm the furnace fires, heats, and cycles off normally.
