It converts 120V line voltage down to the 24V signal required to power every low-voltage control circuit in your system — including the thermostat, gas valve, inducer relay, and control board. When this transformer fails, the furnace loses all 24V control power: nothing responds, the thermostat goes blank, and the system is completely inoperative. Part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e has been superseded by the current OEM part \u003cstrong\u003eHT680054\u003c\/strong\u003e, which is a direct drop-in replacement with identical electrical specifications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary Voltage: 120 VAC | Secondary Voltage: 24 VAC | VA Rating: 40VA | Frequency: 50\/60 Hz | Phase: Single | Compact 3\" × 2-2\/16\" × 2\" footprint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM transformer wound to factory-exact tolerances. Off-brand transformers frequently underperform at rated VA, causing nuisance tripping of 3A fuses and premature control board failures. Do not compromise the heart of your furnace's control circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and confirm 0V at the transformer primary before touching any wiring. Label all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, non-contact voltage tester.
