The transformer steps down line voltage (120V) to the 24V signal voltage required to power the thermostat, control board, contactor coil, and all low-voltage safety circuits. When this component fails, the entire control circuit goes dark — your thermostat becomes unresponsive, the system will not call for heating or cooling, and no error codes will display because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | OEM part number HT01AW229 | Factory-matched output tolerance for reliable low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer engineered to exact VA and voltage output specifications.
