Replacement involves shutting off power and gas, photographing the existing wiring, transferring the harness plugs, and mounting the board on the standoffs. Most experienced DIYers complete it in 30–45 minutes; if you are unsure about wiring or fault-code interpretation, we recommend a licensed HVAC technician. Always confirm power is disconnected at the breaker before servicing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058129879411,"sku":"GOODMAN-11690","price":184.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-9-pin-control-circuit-board-for-gmnt080-4b-b1809913s","provider":"National HVAC Parts","version":"1.0","type":"link"}
