The transformer steps down 120V line voltage to the 24V signal voltage required to power the thermostat, control board, contactor coil, and all low-voltage safety circuits. When this transformer fails, nothing in the control circuit receives power — the thermostat goes blank, the system ignores all calls for heating or cooling, and no fault codes are generated because the board itself is unpowered.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | Primary: 120V | Secondary: 24V | Factory OEM tolerance | Replaces OEM part number HT01AW229\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and insulated to Carrier's exact VA and thermal specifications.
