Most technicians complete this in under 10 minutes. Always cycle the furnace after replacement to confirm normal operation. If the limit trips repeatedly, investigate airflow (dirty filter, blocked vents, or blower issues) before assuming the switch is bad.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eRestore proper safety protection to your furnace with a genuine Goodman B1370155.\u003c\/em\u003e\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057709171059,"sku":"GOODMAN-7115","price":11.96,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-120f-auxiliary-limit-switch-for-ams80905cxa-b1370155","provider":"National HVAC Parts","version":"1.0","type":"link"}
