OEM Carrier 60VA Control Transformer HT01AW229 for Model PH13NA06000GABAA

This OEM control transformer is the factory-specified replacement for the Carrier PH13NA06000GABAA packaged heat pump unit. The transformer steps down line voltage (115/208/230V primary) to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and control board. When this transformer fails, the result is complete system unresponsiveness: the thermostat goes blank, the unit won't energize, and no fault codes will display because the control circuit has no power. It is one of the most critical components in the system.

• Specs: 60VA power rating | 115/208/230V primary | 24V secondary | 50/60 Hz | Foot-mounted configuration | OEM part number HT01AW229 (supersedes HT01AW229A)
• OEM vs Generic: This is a genuine Factory Authorized Parts (FAP) transformer built to exact Carrier tolerances. Generic aftermarket transformers often run undersized VA ratings that cause nuisance tripping, coil burnout, or premature failure — especially in systems with high 24V circuit loads like zone dampers or communicating thermostats.
• Install difficulty: 3/5 — Requires shutting off all power to the unit before starting. Tools needed: multimeter (to verify 24V output post-install), flathead and Phillips screwdrivers, wire stripper, and needle-nose pliers. Label and photograph all low-voltage wiring connections before disconnecting. Verify input voltage tap matches your supply voltage (115V, 208V, or 230V).
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier PH13NA06000GABAA packaged heat pump. Also fits select Bryant and Payne models specifying the HT01AW229 transformer. Always confirm your unit's control board input voltage and VA requirement before ordering. Our HVAC parts specialists are available to verify fitment — order with confidence.
