Carrier HT680056 Transformer
When you're out in the field and find a secondary side with no voltage, the Carrier HT680056 Transformer is the reliable OEM replacement part you need to restore the 24V control circuit. Built specifically for Carrier, Bryant, and Payne equipment, this 40VA HVAC transformer handles the step-down from a 120V primary to a steady 24VAC secondary output. It is a critical component for powering furnace control boards, ignition modules, and 24V thermostats. With its 50/60 Hz frequency rating and robust internal windings, it maintains terminal stability even under the demanding duty cycles of high-efficiency residential systems. Avoid the "universal" multi-tapped headaches; this genuine HT680056 ensures the footprint and electrical characteristics match the factory specifications for a clean 120V to 24V conversion. Whether you are troubleshooting a furnace not turning on or a dead contactor, this step-down transformer provides the consistent VA capacity required to keep low-voltage circuits operational without overheating or voltage sag.
Key Benefits for Technicians:- Precise Electrical Match: 40VA capacity provides ample headroom for typical residential control loops, including inducer relays and gas valves.
- OEM Reliability: Eliminates compatibility issues often found with generic transformers, ensuring the mounting holes and spade terminals align perfectly.
- Thermal Stability: Engineered to withstand the high ambient temperatures found inside blower compartments and vestibules.
- Broad Compatibility: Direct substitute for many legacy Carrier and Payne furnace transformers, simplifying truck stock.
Is the HT680056 compatible with 208V or 240V systems?
No, this specific model is designed for a 120V primary only. Always verify your line voltage before installation.
What causes this transformer to fail?
Typically, a secondary-side short circuit—often at the contactor coil or thermostat wire—will blow the internal thermal link of the transformer. Always check for shorts before installing the new unit.
Can this be used to power a smart thermostat?
Yes, its 40VA rating is sufficient to power modern "C-wire" Wi-Fi thermostats alongside standard furnace components.
