Mounted on the heat exchanger or supply plenum, it monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger from damage due to restricted airflow.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1370187\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 160°F\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Heat exchanger overheat protection\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GMT115-5B\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAs the furnace's main overheat safety, the \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e limit is the right choice — it is calibrated to the precise 160°F trip point and drops into the factory bracket without modification. Generic limits with a different trip rating can nuisance-trip or fail to protect the heat exchanger. Frequent tripping usually points to airflow restriction (dirty filter, undersized ducts, weak blower).\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Cut power, remove the access panel, unplug the terminals, remove the two mounting screws, and install the new switch in the same position.
