It monitors heat-exchanger temperature and opens the burner circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. A limit switch that trips prematurely or fails open will shut the furnace down or cause short-cycling; this OEM switch restores correct, safe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 1370906S\u003c\/li\u003e\n\u003cli\u003ePart Type: High-Limit Safety Switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eInsertion Length: 7 inch\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GUPI120-5 gas furnace\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement — matches factory temperature and length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman switch is calibrated to the exact 150°F trip point and 7-inch probe depth specified for the GUPI120-5 heat exchanger. Because a limit switch is a life-safety device, matching the OEM trip temperature and insertion length is critical — a substitute with a different setpoint can either nuisance-trip or fail to protect the exchanger. Always match OEM specs here.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Disconnect power, remove the two mounting screws, transfer the wire leads, and install the new switch at the same depth. About 15–20 minutes. Because this is a gas-furnace safety control, professional installation is recommended.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058196169075,"sku":"GOODMAN-1370906S","price":26.2,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150-f-7-inch-limit-switch-for-gupi120-5-furnace-1370906s","provider":"National HVAC Parts","version":"1.0","type":"link"}
