Positioned on the heat exchanger housing, this 200°F primary limit continuously monitors supply-plenum temperature and de-energizes the gas valve if the furnace overheats due to low airflow or a stuck blower — preventing heat-exchanger stress and nuisance failures. Using the factory-spec switch keeps the 200°F trip point and mounting geometry exactly as engineered.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 200°F primary high-limit\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger overheat protection\u003c\/li\u003e\n\u003cli\u003eReset type: Auto-reset on cool-down\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80905CXAA and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370189\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM option\u003c\/strong\u003e is the original Goodman-sourced limit for guaranteed calibration and fit.
