It converts 120V line voltage to the 24V signal required by the thermostat, control board, and all low-voltage components in your system. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to any call for heating or cooling, and no error codes are displayed because the board itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number HT01BD242 | 120V primary \/ 24V secondary | 40VA rated | Class 2 insulated windings | Factory-matched output for Carrier control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to Carrier's exact VA rating and voltage tolerance.
