A tripped or failed limit switch commonly causes no-heat calls, blower running without the burner, or repeated overheating lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 240°F (auto-reset primary limit)\u003c\/li\u003e\n\u003cli\u003eInsertion depth: 3 inches\u003c\/li\u003e\n\u003cli\u003eFunction: High-limit \/ overheat safety control\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNT060-3 and cross-compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 1370903S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 1370903S\u003c\/strong\u003e is calibrated to the exact 240°F trip point and probe length specified for your furnace, so it protects the heat exchanger without nuisance trips. Generic limit switches with different trip temps or probe depths can either fail to protect or shut the furnace down prematurely. For a temperature-critical safety part, always match OEM.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — 15–30 minutes. Shut off power, note the wiring, remove the two mounting screws, and transfer the spade connectors to the new switch. Ensure the probe seats fully into the plenum and the bracket sits flush. Because this is a safety control, do not bypass it — replace with the correct OEM part.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058128372083,"sku":"GOODMAN-11639","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-240-f-primary-limit-switch-for-gmnt060-3-1370903s","provider":"National HVAC Parts","version":"1.0","type":"link"}
