Positioned on the heat exchanger deck, the primary limit is the furnace's main overheat guardian: it senses supply-air temperature and shuts down the burners if heat rises beyond safe levels due to insufficient airflow. This automatic-reset 150°F control is one of the most common furnace safeties to fail, showing up as no-heat, short cycling, or the burners lighting then dropping out.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eReset type: Automatic reset\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit overheat safety\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80903BNAA 80% gas furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370198\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e part arrives pre-calibrated to the precise 150°F set point and correct disc size your furnace requires. Aftermarket snap-disc limits matched only by temperature can fit physically but may respond differently, leading to nuisance lockouts or delayed protection. Because this is the primary safety limit, we recommend installing the OEM component.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy (1\/5)\u003c\/strong\u003e. Turn off power and gas, pull the two spade connectors, remove the mounting screws, and fit the new limit in the identical position and orientation. Roughly 15 minutes with basic hand tools.
