The transformer steps down 120V line voltage to the 24V signal used by your thermostat, contactor coil, gas valve, and control board. When it fails, the entire control circuit goes dead — your thermostat goes blank, the system stops responding to calls for heating or cooling, and no components energize. If you have 120V at the primary but 0V at the secondary, this transformer is your diagnosis.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | OEM part number HT01BC116 | Factory-matched for Carrier N6A48NG481459 packaged units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances required by the factory control board.
