This safety control monitors heat-exchanger\/plenum temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, a dirty filter, or blower failure. A tripped or failed limit switch causes no-heat or short-cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 1370901S\u003c\/li\u003e\n\u003cli\u003eType: Temperature high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eTrip point: 180°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eAction: bimetal snap-disc, auto-reset (verify mount for your model)\u003c\/li\u003e\n\u003cli\u003eFit: Goodman GMN120-5 and cross-compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e switch is calibrated to Goodman's exact 180°F trip temperature and mounting flange. Because this is a safety device, an incorrectly rated generic can trip early (nuisance shutdowns) or too late (overheating). We strongly recommend OEM for limit controls.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — 15 to 20 minutes.

Correct temperature rating is critical — always match 180°F.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058126995827,"sku":"GOODMAN-11598","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-180-f-limit-switch-for-gmn120-5-1370901s","provider":"National HVAC Parts","version":"1.0","type":"link"}
