The transformer steps down line voltage (115V, 208V, or 230V primary) to a safe 24V secondary output, powering the low-voltage control circuit that operates your thermostat, contactor coil, and system logic. When the transformer fails, the entire control circuit goes dead — the thermostat loses power, the system becomes completely unresponsive, and no heating or cooling will occur. A burnt smell or visible scorch marks on the transformer body are classic signs of failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60 VA rating | Primary: 115 \/ 208 \/ 230 VAC | Secondary: 24V | Foot-mounted design | OEM part number HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, built to exact VA rating, mounting footprint, and winding specifications.
