The transformer steps down high-voltage line power (208\/240\/480V primary) to the 24V AC signal used by your thermostat, contactor coil, and all low-voltage control circuits. When this part fails, the entire control circuit goes dark — the thermostat loses power, no calls for heating or cooling are processed, and the unit sits completely unresponsive. It is one of the first components to check when nothing works.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 75VA output | Primary: 208\/240\/480V | Secondary: 24V AC | 50\/60 Hz | Foot-mount configuration | OEM part number HT01BD242\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier factory part — engineered to exact VA rating and insulation class.
