Generic aftermarket limit switches may carry a different trip point or contact rating, which can cause premature lockouts or fail to protect the heat exchanger. For a safety device, we recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Easy.\u003c\/strong\u003e A DIY-capable homeowner can typically replace this switch in 15–20 minutes with a nut driver. Always cut power to the furnace at the breaker before servicing, photograph the wiring, and transfer the leads one at a time. If the furnace repeatedly trips on limit after replacement, have a technician verify airflow and blower operation.\u003c\/p\u003e\u003cp\u003eIf you are unsure whether this is the correct switch for your unit, match your furnace's model and serial plate before ordering, or contact us at info@nationalhvacparts.com.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057614307699,"sku":"GOODMAN-5400","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-for-amh80704bxcb-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
