Mounted on the heat exchanger or plenum, it monitors supply-air temperature and opens the burner circuit if the furnace overheats — typically from restricted airflow such as a dirty filter or failed blower. This auto-reset control is a primary safety device that prevents heat-exchanger damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eTrip point: 150°F (factory-calibrated)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic on cooldown\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner circuit on high supply-air temperature\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMH950703BXAC and compatible GMH\/GMS furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact 150°F trip point specified for the GMH950703BXAC. Generic limits with different setpoints can nuisance-trip or, worse, fail to open in time. Because this is a life-safety control, OEM is strongly recommended and helps keep your warranty intact.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5)\u003c\/strong\u003e — Disconnect two wires, remove the mounting screws, and swap in the new switch. Shut off power and gas first. If the old limit was tripping, correct the underlying airflow problem (filter, blower, ductwork) before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058113495411,"sku":"GOODMAN-11179","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-primary-limit-switch-for-gmh950703bxac-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
