OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH10JA03000GAGAA

This is the factory-authorized OEM replacement control transformer for the Carrier PH10JA03000GAGAA packaged heating unit. Part number HT01AW229, this 60VA foot-mount transformer steps down the primary voltage (115, 208, or 230VAC) to a 24VAC secondary signal that powers the entire low-voltage control circuit — including the thermostat, gas valve, contactor coil, and control board. When this transformer fails, the result is a completely unresponsive system: the thermostat goes blank, no components energize, and no fault codes appear because there is no control power to drive them.

• Specs: 60VA power rating | Primary: 115/208/230VAC multi-tap | Secondary: 24VAC | Foot-mount configuration | 50/60 Hz rated | Factory-matched OEM tolerance
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers deliver stable, regulated 24VAC output within tight tolerance. Off-brand units often produce voltage sag under load, causing erratic control board behavior, nuisance lockouts, and premature component failure.
• Install difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, multimeter (verify 0V before touching terminals), wire nuts or terminal connectors. Photograph all wiring before removal. The higher 60VA rating means leads may carry more current — ensure connections are tight and insulated.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
