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 control circuits. When this transformer fails, the entire control system goes dark — the thermostat shows no power, the system won't respond to any calls for heating or cooling, and you may measure zero volts on the secondary side of the transformer.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | Primary: 120V | Secondary: 24V | OEM part number HT01BC116 | Factory-matched to Carrier N6A48NG482020 control circuit requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and potted to exact VA and thermal specifications for your unit.
