A failed transformer kills the entire low-voltage side: the thermostat goes dark, no heating or cooling call gets through, and the system sits unresponsive. Built to Carrier's exact primary and secondary voltage and VA rating, this transformer is a direct factory replacement for the FIOP200C501GA, supplying clean, correctly rated power to the control board and accessories. Installation is a moderate, DIY-friendly job: shut off power, label the primary and secondary leads, unbolt the bracket, and wire the new transformer identically. Most installs take 20 to 30 minutes with basic tools and a meter to verify 24V output. Choosing the correct OEM transformer prevents under-voltage faults and erratic operation caused by mismatched VA ratings. We keep this part in stock and ship same-day on orders before 3PM CST, restoring control power fast. Check for a blown low-voltage fuse before replacing the transformer.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model FIOP200C501GA.\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":62942994661747,"sku":"carrier-transformer-fiop200c501ga","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-carrier-transformer-fi_f69af09e-e285-4ba2-bfdd-cdc3d7ee0343.jpg?v=1781473433","url":"https:\/\/nationalhvacparts.com\/products\/carrier-transformer-fiop200c501ga","provider":"National HVAC Parts","version":"1.0","type":"link"}
