Designed specifically for the GB1AAV036065ACJA gas furnace, it steps down 120V line voltage to the precise 24V needed for safe, reliable operation of the control circuit. When a transformer fails, the furnace goes completely unresponsive — no thermostat call, no ignition, no blower — making this a critical first part to check on a dead furnace. This genuine factory component delivers exact voltage and amperage specs, protecting your downstream controls from damage. Installation is moderate: cut power at the breaker, label and disconnect the primary and secondary leads, unbolt the old transformer, and mount the replacement. Most techs complete the swap in 20-30 minutes; a multimeter confirms the diagnosis. Choosing OEM ensures correct mounting and lead configuration with no adapters. In stock now and ships same-day on orders placed before 3PM CST. Compatibility guaranteed for your GB1AAV036065ACJA furnace so you order with confidence.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV036065ACJA.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62942819156339,"sku":"carrier-transformer-gb1aav036065acja","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-carrier-transformer-gb_3f6e5f5c-f35d-4c40-b148-24c9446196f5.jpg?v=1781473460","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-gb1aav036065acja","provider":"National HVAC Parts","version":"1.0","type":"link"}
