The transformer steps down line voltage from 120V to the 24V signal required to power the control board, thermostat, and low-voltage control circuit throughout your system. When the transformer fails, the entire control circuit goes dead — your thermostat will display nothing or fail to call for heating or cooling, and the system will not respond to any commands.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | Primary: 120V | Secondary: 24V | OEM part number HT01CN236 | Factory-matched output tolerance for stable control voltage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer built to exact factory voltage and VA specifications.
