OEM Carrier Transformer 460V Primary / 230V Secondary 1564VA for Model PY4GEWB60090AA

This is the genuine OEM factory-replacement transformer (part number HT01BC701) for the Carrier PY4GEWB60090AA packaged HVAC unit. The transformer steps down the 460V line-voltage supply to a 230V secondary output at 1564VA, delivering reliable power conversion for the unit's electrical subsystems. When this transformer fails, the result is typically a complete loss of system operation — no heating, no cooling, and no response from the control circuit — making rapid, accurate replacement critical to restoring service.
