OEM Carrier Transformer 460V Primary 230V Secondary 1564VA for Model PY4GEWA36060AA

This is the genuine OEM factory-replacement transformer (part number HT01BC701) for the Carrier PY4GEWA36060AA packaged rooftop unit. This heavy-duty transformer steps high-voltage 460V primary power down to a 230V secondary output at 1564VA, delivering stable power to critical unit sub-circuits and components. When this transformer fails, the entire unit may go dark — no thermostat response, no contactor operation, and no blower or compressor activity — making it one of the first components to verify during a total system no-power diagnostic.
