This OEM control transformer (part number HT01AW229) is the factory-specified replacement for the Carrier PH13PR060000ACAA heat pump system. The transformer steps down the 115/208/230V line voltage to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control components. When this transformer fails, the entire control circuit goes dead — the system will not respond to the thermostat, and no heating or cooling operation will occur.
Compatibility: Direct OEM replacement for Carrier model PH13PR060000ACAA heat pump units. Confirm your unit's supply voltage (115V, 208V, or 230V) and select the correct primary tap on installation. Cross-references include HT01AW229A. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — contact us today.
