OEM Carrier Control Transformer 60VA 115/208/230V — 24V Secondary for Model PH13NA060000ABAA

This is the genuine OEM Carrier control transformer (part number HT01AW229), factory-specified for the Carrier PH13NA060000ABAA packaged heat pump unit. The control transformer steps down high-voltage line power (115/208/230V primary) to the 24V AC signal used by your thermostat, contactor coil, and all control-circuit components. When this transformer fails, the entire control circuit goes dead — the thermostat will display nothing or lose communication, the contactor won't energize, and the system will not respond to any heating or cooling calls.

• Specs: 60VA power rating | 115/208/230V AC primary voltage | 24V AC secondary voltage | 50/60 Hz | Foot-mounted configuration | Factory-matched Carrier OEM design
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and voltage tolerances, protecting sensitive control boards from voltage fluctuations. Generic aftermarket units may run outside tolerance, risking nuisance trips or board damage over time.
• Install difficulty: 2/5 — Always shut off power at the disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Photograph all wiring connections before removal. Mount securely using existing foot-mount hardware.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed and factory-matched for the Carrier PH13NA060000ABAA packaged heat pump unit. Also fits select Bryant and Payne models using the same 60VA 115/208/230V-24V control transformer specification — verify your data plate before ordering. Cross-references: HT01AW229A.
