OEM Carrier Transformer 460V Primary / 230V Secondary 1564VA for Model PY3GEAA48115AA

This is the genuine OEM replacement transformer, part number HT01BC701, factory-specified for the Carrier PY3GEAA48115AA packaged rooftop unit. The transformer steps high-voltage primary power (460V) down to a usable secondary voltage (230V) at a robust 1564VA capacity, supplying the power necessary to run auxiliary loads and internal electrical subsystems within the RTU. When this transformer fails — due to electrical surge, short-circuit in the control wiring, or age-related winding breakdown — the result is often a complete system shutdown: no thermostat response, no contactor pull-in, and no HVAC operation whatsoever.
