Always disconnect power to the furnace before servicing. If the switch trips repeatedly after replacement, have a licensed HVAC technician diagnose the underlying cause (restricted airflow, dirty filter, or failed blower).\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058084921715,"sku":"GOODMAN-10520","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-gks90453bxaa-10123533","provider":"National HVAC Parts","version":"1.0","type":"link"}
