The transformer steps down line voltage from 120V to the 24V AC signal required to power your thermostat, control board, contactor coil, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system will not respond to any call for heating or cooling, and no fault codes will display because the board itself has no power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Primary: 120V AC | Secondary: 24V AC | VA Rating: 40VA | OEM Part Number: HT01BD236 | Factory-matched to Carrier C48A206052 control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact factory VA and voltage tolerances.
