The transformer steps down 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer, and control board. When the transformer fails, the furnace goes completely silent: the thermostat goes blank, no ignition sequence initiates, and nothing responds to a call for heat. A shorted low-voltage component (bad gas valve, wiring fault) is a common root cause of transformer burnout, so always check the secondary circuit before installing the replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary 120V AC | Secondary 24V AC | 40VA rated | Class 2 step-down transformer | Direct OEM replacement for HT01BC116 (superseded by HT680054)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is wound and insulated to Carrier's exact factory specification, ensuring precise 24V output and correct VA headroom for the full low-voltage load. Generic transformers frequently run at marginal VA ratings, risking thermal overload and repeat failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Cut power at the breaker and verify zero voltage before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter (to confirm 24V output on secondary after install). Photograph all wiring connections before disconnecting. Inspect secondary wiring for shorts before energizing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.

Note: OEM part number HT01BC116 has been superseded by HT680054 — both are the same 120V–24V 40VA transformer. Verify your existing transformer's primary\/secondary voltage and VA rating on its label before ordering.
