The transformer steps down 120V line voltage to 24V AC to power the low-voltage control circuit — including the thermostat, control board, and contactor coil. When this component fails, the entire control circuit goes dark: the thermostat loses power, the system becomes completely unresponsive, and no heating or cooling operation is possible.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rated | Replaces OEM part number HT01CN236 | Factory-matched insulation class and VA capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer wound to exact factory specifications.
