OEM Carrier 60VA Control Transformer 115/208/230V–24V for Model PH10PA060000ACAA

This OEM control transformer is the factory-specified replacement for the Carrier PH10PA060000ACAA packaged heat pump unit. The transformer steps down incoming line voltage (115V, 208V, or 230V) to the 24V DC signal required to power the low-voltage control circuit — including the thermostat, contactor coil, control board, and all system relays. When this transformer fails, the entire control circuit goes dead: the thermostat displays nothing, the system will not respond to any call for heating or cooling, and in some cases the unit's 24V fuse will blow repeatedly as a symptom of an overloaded secondary winding.

• Specs: 60VA rating | Primary: 115V / 208V / 230V multi-tap | Secondary: 24V | Class 2 insulation | OEM part number HT01AW229 (also referenced as HT01AW229A)
• OEM vs Generic: This factory OEM unit is wound to exact Carrier tolerances with built-in thermal overload protection. Generic transformers frequently under-deliver on VA capacity, causing nuisance trips and premature failure under full control-circuit load.
• Install difficulty: 2/5 — Shut off all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter, and wire nuts. Always photograph the existing wiring and note the primary tap in use (115V, 208V, or 230V) before disconnecting leads. Verify 24V output at secondary terminals with a multimeter before closing the panel.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed for use in the Carrier PH10PA060000ACAA packaged heat pump. Cross-references include HT01AW229A, CIN-TRAN, 30-BV2006, and 30-1814A.
