This normally-closed thermal safety control monitors heat-exchanger\/plenum temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, dirty filters, or blower failure. A tripped or failed limit switch is a common cause of short-cycling and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on rise)\u003c\/li\u003e\n\u003cli\u003eFunction: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH950703BXAB and related furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part #: 20162903\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM limit switches carry the exact trip temperature and mounting footprint Goodman engineered for this furnace.
