Typically mounted in the blower compartment, this auxiliary (secondary) limit opens and shuts the furnace down if the blower-section temperature climbs abnormally — protecting against restricted airflow, a stuck blower, or a clogged filter. If your furnace runs briefly and then trips on a limit fault, a failed auxiliary limit is a common culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370155\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 120°F\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary \/ secondary limit (auto or manual reset per design)\u003c\/li\u003e\n\u003cli\u003eFunction: Blower-compartment overheat protection\u003c\/li\u003e\n\u003cli\u003eFits Model: ADV80905CXBB and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" spade connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370155\u003c\/strong\u003e is set to Goodman's exact 120°F threshold and mounting geometry, so the safety trip matches the cabinet's design airflow limits.

Roughly 15 minutes. Check the air filter and blower for restrictions, since chronic overheating often points to an airflow problem rather than the switch itself.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057512006003,"sku":"GOODMAN-3463","price":11.96,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-120-f-auxiliary-limit-switch-for-adv80905cxbb-b1370155","provider":"National HVAC Parts","version":"1.0","type":"link"}
