The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, contactor coil, and control board. When this transformer fails, the entire low-voltage control circuit goes dead — your thermostat goes blank, the system stops responding to calls for heating or cooling, and nothing turns on. It is one of the first components to check when a system shows zero response to any thermostat command.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input 120V AC | Output 24V AC | 40VA rating | OEM part number HT01BC116 | Factory-matched to Carrier N6A48NG481822 electrical specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM transformer is wound to exact VA and voltage specifications.
