The transformer steps down line voltage from 120V to 24V AC to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When this component fails, the entire control circuit goes dead: your thermostat goes blank, the system produces no response to calls for heating or cooling, and no fault codes appear because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | Class 2 low-voltage output | OEM part number HT01CN241 | Direct factory replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine OEM Carrier transformer built to exact VA rating and insulation class specifications.
