Mounted on the heat exchanger or burner bulkhead, this thermal switch monitors supply-air temperature and shuts down the burners if airflow is restricted — from a dirty filter, failing blower, or blocked ducts — preventing heat-exchanger damage and unsafe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (primary high limit)\u003c\/li\u003e\n\u003cli\u003eFunction: Automatic-reset thermal safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH951155DXAD and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162903 is calibrated to the exact trip point and mounting footprint your furnace's control sequence expects. Generic limit switches with a different set point can nuisance-trip during normal heating cycles or, worse, fail to open soon enough to protect the heat exchanger. On a safety control, matching the factory specification is essential.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eStraightforward for a technician — cut power at the disconnect, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. Verify continuity and confirm normal cycle operation after installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058124570995,"sku":"GOODMAN-11511","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-primary-limit-switch-for-gmh951155dxad-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
