The transformer steps down line voltage from 120V to 24V to power the low-voltage control circuit — including your thermostat, contactor coil, and control board. When this transformer fails, the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any calls for heating or cooling, and nothing works despite power being present at the unit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rated | OEM part number HT01CN236 | Factory-matched to Carrier FA4ANF024008AGAA control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound and rated to exact factory specifications.
