It converts 230V line voltage to the 24V AC signal that powers your thermostat, control board, and all low-voltage control circuits. 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. It is often the first component to check when a unit has completely stopped communicating.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA rating | 230V primary input | 24V secondary output | OEM part number HT01AW230 | Factory-matched for Carrier FF1ANA024000AAAA fan coil units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound to exact Carrier factory specifications, ensuring stable 24V output under full control-circuit load.
