The transformer steps down 230V line voltage to 24V AC, powering the thermostat, control board, and all low-voltage switching components. When this transformer fails, the result is total system silence — a blank thermostat, an unresponsive control board, and no heating or cooling operation whatsoever. It is one of the first components to check when your system shows absolutely no signs of life.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA rated | 230V primary input | 24V secondary output | OEM part number HT01AW230 | Factory-matched for Carrier FD3ANA030010AAAA fan coil units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM transformer is wound and insulated to Carrier's exact factory specifications, including proper VA capacity and thermal protection.
