OEM Carrier 60VA Control Transformer HT01AW229 for Model PH13NR060000ACAA

The Carrier HT01AW229 is the factory-specified OEM control transformer for the PH13NR060000ACAA heat pump package unit. This 60VA step-down transformer converts high-voltage line power (115V, 208V, or 230V primary) down to a safe 24VAC secondary signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and safety switches. When this transformer fails, nothing works: the thermostat goes dark, the contactor never energizes, and the system is completely dead. A failed transformer is often confirmed by measuring 0VAC on the 24V secondary while line voltage is present at the primary.

• Specs: 60 VA power rating | 115/208/230 VAC primary (multi-tap) | 24 VAC secondary | 50/60 Hz | Foot-mounted chassis | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and impedance specs, preventing nuisance tripping of downstream fuses and ensuring long-term reliability. Generic aftermarket units may be under-rated for VA, causing overheating and premature failure under peak load.
• Install difficulty: 3/5 — Disconnect all power at the disconnect box before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, voltage tester. Label all control wires before disconnecting from the old transformer. Verify primary tap selection matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.

Compatibility: Designed for the Carrier PH13NR060000ACAA packaged heat pump unit. The multi-tap primary (115/208/230V) makes this transformer suitable across a range of Carrier, Bryant, and Payne equipment sharing the HT01AW229 specification. Always verify your unit's control voltage and VA requirements on the data plate before ordering. Have a fitment question?
