As the primary high-limit control, it continuously senses supply-air\/heat-exchanger temperature and shuts off the gas valve if the furnace exceeds its safe operating limit — preventing overheating, heat-exchanger stress, and fire hazards. Unlike a manual switch, this automatic control resets once temperatures return to normal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eComponent Type: Primary limit temperature control (auto-reset high limit)\u003c\/li\u003e\n\u003cli\u003eReset Type: Automatic\u003c\/li\u003e\n\u003cli\u003eCompatible Model: AMVC80805DNBD and related AMVC\/GMVC series furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: De-energizes the gas valve on over-temperature\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit is factory-calibrated to a specific trip point matched to the AMVC80805 heat exchanger and airflow.
