Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and opens the control circuit if the blower fails or airflow is restricted, protecting the heat exchanger from cracking due to overheating. A furnace that short-cycles on high limit or shuts down after a few minutes of heat often needs this switch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary auto-reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip temperature: 150°F (auto-reset on cooldown)\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" quick-connect spades\u003c\/li\u003e\n\u003cli\u003eMount: Bulkhead flange, 2-screw\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMVC80604BNAA and compatible models\u003c\/li\u003e\n\u003cli\u003eOEM Part No: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe 150°F trip point is model-specific; installing a generic limit with a different rating can allow dangerous heat-exchanger temperatures or cause constant nuisance trips.
