It converts 120V line voltage down to 24V AC to power every low-voltage control circuit in the system — including the thermostat, control board, gas valve, and zone controls. When this transformer fails, the furnace goes completely silent: no thermostat response, no inducer start, and no error codes. If you're measuring 0V between the R and C terminals on the control board, a failed transformer is the first component to suspect.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | Foot-mount configuration | Wire lead connections | 60 Hz | Includes 3A fuse protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is factory-matched to Carrier's exact VA rating and mounting footprint. Generic transformers are frequently mismatched in VA output, leading to overheating or nuisance tripping of the control board's fuse — a problem confirmed by field installers. OEM ensures a drop-in fit with no modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and confirm zero voltage before disconnecting leads. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Photograph or label all wire connections before removal. Check and replace the low-voltage fuse on the control board as a best practice during this repair.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.

OEM part number HT01BC116 has been superseded by Carrier part number \u003cstrong\u003eHT680054\u003c\/strong\u003e — both are factory-authorized and interchangeable. Also fits many Carrier, Bryant, and Payne furnace models sharing the 120V-24V 40VA transformer specification. Verify your unit's data plate and existing transformer ratings before ordering.
