Installed on the heat-exchanger or supply-plenum side, the primary limit is the furnace's main over-temperature safeguard. It monitors discharge air temperature and shuts off the burners if the furnace overheats due to insufficient airflow, protecting the heat exchanger from cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 210°F (open on rise, auto reset)\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger over-temperature protection\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370190\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNTE100-4 and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause the primary limit protects the most expensive component in the furnace, the exact 210°F calibration of the OEM B1370190 matters. Generic limits with looser tolerances can trip early (short-cycling) or, worse, trip late and allow damaging heat buildup. The genuine Goodman part guarantees the manufacturer-specified set point and mounting fit.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — Power off, unplug the two leads, remove the mounting screws, and reinstall the replacement flush against the plenum. Persistent tripping usually points to airflow restriction (dirty filter, blocked coil, or undersized ducting) rather than the switch itself.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058133713267,"sku":"GOODMAN-11812","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-210-f-primary-limit-switch-for-gmnte100-4-b1370190","provider":"National HVAC Parts","version":"1.0","type":"link"}
