OEM Carrier Power Transformer 460V Primary / 230V Secondary 1564VA for Model PH3GEAA60000AA

This genuine OEM Carrier power transformer (part numbers HT01BC701 and supersede HT01BD242) is the factory-specified step-down transformer for the Carrier PH3GEAA60000AA packaged rooftop unit. Rated at a heavy-duty 1564VA, this transformer steps high-voltage 460V primary supply power down to a 230V secondary output to feed downstream components and control circuits within the RTU. When this transformer fails, the result is typically a complete loss of system function — no thermostat response, no blower, no compressor — because the entire low-voltage control circuit loses its power source. A failed transformer may also present as blown fuses, tripped breakers on the secondary side, or a burning/overheating smell from the electrical compartment.
