The control transformer steps down the high-voltage supply (115\/208\/230V primary) to the 24V AC signal required to power the thermostat circuit, control board, contactor coil, and all low-voltage control functions. When this transformer fails, the entire low-voltage 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 appear because the board itself has lost power.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA capacity | Primary: 115\/208\/230V AC | Secondary: 24V AC | Foot-mount chassis | OEM part number HT01AW229 (also listed as HT01AW229A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part built to exact VA, voltage, and thermal protection specifications.
