Generic universal limits often carry approximate trip points and require re-drilling or bracket adaptation, which can compromise the safety timing your furnace's control board expects. For a mission-critical safety component, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — typically a 15-minute repair. Disconnect power, unplug the two spade terminals, remove the mounting screws, and swap in the new switch. No special tools required. If your furnace is short-cycling on limit or failing to fire, this is a common and inexpensive fix. Always confirm proper airflow and a clean filter, as a tripping limit can also indicate restricted airflow.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057849680243,"sku":"GOODMAN-7885","price":21.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-150f-primary-limit-switch-for-amvc800603bxab-20162903","provider":"National HVAC Parts","version":"1.0","type":"link"}
