Its sole job is converting 120V line-voltage power down to the 24V AC signal that drives every low-voltage component in your system — the thermostat, control board, gas valve, and inducer relay. When this transformer fails, \u003cstrong\u003enothing responds\u003c\/strong\u003e: the thermostat goes blank, the furnace is completely unresponsive, and you may measure 0V between the R and C terminals on the control board. OEM part HT01BC116 has been superseded by \u003cstrong\u003eHT680054\u003c\/strong\u003e, which ships in a Carrier factory-authorized parts box and is a direct plug-in replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary input 120V AC | Secondary output 24V AC | 40VA rated | 60 Hz | Foot-mount configuration | Wire lead connections with pre-installed female connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and tested to Carrier's exact VA and voltage tolerances. Generic units often deliver unstable output voltage, which can damage your control board — an $150–$200 part. The OEM replacement is the safer, longer-lasting choice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off all power to the furnace at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Photograph or label all wiring connections before disconnecting. Verify 24V output at R–C terminals after installation. Consider adding an inline 3A fuse to protect against future low-voltage shorts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
