Without it, the entire low-voltage control circuit goes dead — no thermostat response, no ignition sequence, no heat at all. A transformer can fail from age, a shorted control wire, or a power surge. Built to exact Carrier specifications, this transformer delivers stable, correctly rated 24V output to keep every control component operating reliably. Installation is moderate and takes a technician about 20-30 minutes: cut power, label and transfer the primary and secondary leads, remount the transformer, and verify output before restoring power. Always check for the short that may have caused the original failure. Genuine OEM ensures correct voltage and protects your warranty. In stock now — orders placed before 3PM CST ship the same day. Bring your furnace's control system back to life with the exact transformer Carrier engineered for this model.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV036045ABJA.\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":62942827348339,"sku":"carrier-transformer-gb1aav036045abja","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_5bdc12f5-96d7-4480-a9c8-0bd54c2d60cf.jpg?v=1781473444","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-gb1aav036045abja","provider":"National HVAC Parts","version":"1.0","type":"link"}
