The transformer converts 120V line voltage to the 24V AC signal that powers every low-voltage component in your system — thermostat, gas valve, ignition control board, and zone controls. When this part fails, the furnace goes completely dark: no thermostat response, no ignition attempt, no blower activity. A failed transformer is often mistaken for a bad control board, so always verify 24V output at the R and C terminals before condemning more expensive components.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | 60 Hz | Foot-mount configuration | Wire lead connections with compatible female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM-spec unit is wound to exact Carrier factory tolerances, ensuring stable 24V output under full VA load. Generic transformers are frequently under-rated, causing voltage sag that triggers nuisance lockouts and premature control board failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and disconnect the furnace before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph existing wire connections before disconnecting. Confirm 24V output at R–C terminals after installation before restoring full power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
