It monitors heat-exchanger temperature: it signals the blower and, if the plenum overheats from restricted airflow, it opens to cut the gas valve and prevent heat-exchanger damage. A failed limit switch shows up as short-cycling on limit, or a furnace that heats but never shuts the burners off correctly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 160°F (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003eInsertion depth: 7 in. probe\/element length\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset fan \u0026amp; limit control\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect spades\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana GMP075-3 and compatible GMP furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 1370908S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBoth the \u003cstrong\u003e160°F set point and the 7-inch length\u003c\/strong\u003e must match your furnace — a shorter probe reads air temperature incorrectly and trips at the wrong time. This genuine Goodman OEM switch is factory-calibrated to spec, unlike adjustable universal limits that require field setup and can drift.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eAbout 20 minutes. Disconnect power, note the wire positions, remove the two mounting screws on the heat-exchanger panel, and withdraw the probe. Insert the new switch to the same depth, refasten, and reconnect the spades. Verify a full heat cycle with the blower staging on and off normally.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eGenuine Goodman part shipped fast from National HVAC Parts.\u003c\/em\u003e\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058135482739,"sku":"GOODMAN-11853","price":26.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-160-f-7-in-fan-limit-switch-for-gmp075-3-1370908s","provider":"National HVAC Parts","version":"1.0","type":"link"}
