The transformer steps down line voltage from 120V to the 24V AC signal that powers your thermostat, control board, contactor coil, and all low-voltage control circuits. When this component fails, the entire control circuit goes dead — the thermostat goes blank, the system will not respond to any call for heating or cooling, and no safety or operating sequence can be initiated. If your unit is completely unresponsive despite confirmed line power, the transformer is one of the first components to test.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | VA Rating: 40VA | OEM Part Number: HT01BD236 | Replaces factory original unit exactly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to Carrier's exact VA rating and thermal protection specifications.
