This transformer steps down line voltage (208\/240V) to the 24V signal required to power the thermostat, control board, gas valve, and all low-voltage control circuitry. When the transformer fails, the entire control circuit goes dead — no thermostat response, no call for heat or cool, and no system operation whatsoever. Replacing it with a genuine OEM part restores factory-matched performance instantly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 208\/240V primary input | 24V secondary output | 40VA power rating | 50\/60Hz | Carrier OEM part # HT01BD209\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and tested to exact Carrier factory tolerances, ensuring stable 24V output under full load.
