OEM Carrier Control Transformer 60VA 115/208/230V-24V for Model PH10JA02400GAGAA

This OEM control transformer (part number HT01AW229) is the factory-specified replacement for the Carrier PH10JA02400GAGAA. The transformer steps down line voltage from 115, 208, or 230V to 24V AC to power the unit's entire low-voltage control circuit — including the thermostat, contactor coils, and control board. When this transformer fails, nothing works: the thermostat goes blank, the system won't respond to calls for heating or cooling, and fuses or breakers may trip. A failed transformer is one of the most commonly misdiagnosed HVAC faults — always verify output voltage at the secondary terminals with a multimeter before condemning a board.

• Specs: 60 VA power rating | Primary voltage: 115/208/230V AC, 50/60 Hz | Secondary voltage: 24V AC | Foot-mount configuration | OEM part number HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound and insulated to exact factory specifications, ensuring correct VA capacity and long-term reliability. Generic units often underrate their VA capacity, causing nuisance overloads and premature failure under full control-circuit loads.
• Install difficulty: 3/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, needle-nose pliers. Always verify primary input voltage matches your supply before powering up. Label all wire connections before removing the old transformer.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PH10JA02400GAGAA. Also cross-references as HT01AW229A and is compatible with select Bryant and Payne equipment sharing the same 60VA, 115/208/230V-24V transformer specification — verify your unit's wiring diagram and data plate before ordering.
