This is the genuine OEM replacement transformer (part number HT01BC701) for the Carrier PY3GEAA42060NA packaged rooftop unit. This heavy-duty step-down transformer converts a 460V primary supply voltage to a 230V secondary output at a robust 1564VA rating, providing stable power distribution to the unit's internal subsystems and controls. When this transformer fails, the result is typically a complete loss of system operation — no fan, no compressor response, and no thermostat communication — because downstream components are starved of properly conditioned voltage.
Compatibility: Designed for use in the Carrier PY3GEAA42060NA commercial packaged rooftop unit. Also compatible with select Carrier, Bryant, and Payne RTU, heat pump, and packaged unit models requiring the HT01BC701 transformer specification. Confirm your unit's voltage and VA requirements against your equipment data plate before ordering. Need fitment confirmation? Our expert team is available to verify compatibility before you buy.
