OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH10JA048000ABAA

This OEM control transformer (part number HT01AW229) is the factory-specified replacement for the Carrier PH10JA048000ABAA packaged unit. The control transformer steps line voltage (115, 208, or 230V primary) down to the 24V AC signal used by your thermostat, contactors, and control board. When this component fails, the entire low-voltage control circuit goes dead — the system will not respond to the thermostat, will not call for heating or cooling, and may blow the 3A or 5A control fuse repeatedly.

• Specs: 60 VA power rating | 115/208/230 VAC multi-tap primary | 24 VAC secondary | 50/60 Hz | Foot-mount configuration | Factory-matched OEM tolerances
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound and insulated to exact VA and voltage specs, minimizing heat buildup and nuisance fuse-blowing that cheaper aftermarket units cause over time.
• Install difficulty: 2/5 — Shut off all power at the disconnect before starting. Tools needed: flathead and Phillips screwdriver, multimeter, wire stripper. Label all low-voltage wires before disconnecting. Verify primary tap wiring matches your supply voltage (208V vs. 230V) before energizing.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH10JA048000ABAA packaged unit. Also referenced under part number HT01AW229A.
