OEM Carrier Transformer 460V Primary / 230V Secondary 1564VA for Model PY4GEWB60115AA

This is the genuine OEM Factory Authorized replacement transformer (part #HT01BC701) for the Carrier PY4GEWB60115AA packaged rooftop unit. This heavy-duty step-down transformer takes a 460V primary input and steps it down to a 230V secondary output at a robust 1564VA capacity, providing reliable power distribution to internal system components. When this transformer fails, the unit will experience complete loss of control power or erratic electrical behavior — nothing will operate as expected until it is replaced with the correct OEM part.
