The transformer steps down 120V line voltage to the 24V signal used by the thermostat, control board, contactor coil, and every other low-voltage component in your system. When it fails, the entire control circuit goes dark — your thermostat goes blank, nothing responds to a call for heat or cooling, and the system appears completely dead even though line power is present.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | OEM part number HT01BC208 | Factory-matched construction for full compatibility with Carrier control circuits\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 VA and voltage tolerances.
