Originally sold under part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e, this transformer has been superseded by the current OEM part \u003cstrong\u003eHT680054\u003c\/strong\u003e — a direct drop-in replacement shipped in Carrier's factory-authorized packaging. The transformer converts 120V line power down to 24V AC, energizing the thermostat circuit, control board logic, gas valve coil, and all other low-voltage components. When it fails, the entire control circuit goes dark: your thermostat will be unresponsive, the furnace will not ignite, and no fault codes will display on the board — because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary voltage 120V AC | Secondary voltage 24V AC | VA rating: 40VA | Frequency: 60 Hz | Single phase | Foot\/chassis mount | Wire lead connections with insulated female quick-connect terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier replacement. Generic transformers frequently use undersized cores and lower-grade winding insulation that can run hot and fail prematurely — or damage downstream low-voltage components by delivering inconsistent output voltage. OEM is the only safe choice when the control board is also at risk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and verify with a non-contact tester before touching any wiring. Label all wire connections and photograph the original wiring before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify 24V output after install). Typical job time: 20–30 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e Backed by Carrier's 1-year OEM parts warranty.
