OEM Carrier 60VA Control Transformer HT01AW229 for Model PH10JA036000AJAA

This is the genuine OEM foot-mounted control transformer for the Carrier PH10JA036000AJAA packaged unit. The transformer steps down the high-voltage supply (115, 208, or 230V primary) to the 24V secondary signal required to power the control board, thermostat circuit, and all low-voltage components. When this transformer fails, the entire control circuit goes dead — the system will not respond to thermostat calls for heating or cooling, and in many cases nothing will appear to happen at all.

• Specs: 60 VA rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | Foot-mounted configuration | OEM Part Number: HT01AW229 / HT01AW229A
• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM transformer engineered to exact Carrier tolerances. Generic transformers often carry lower VA ratings or inferior core materials that lead to overheating, voltage sag under load, and premature failure — risking damage to the control board.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter. Label all low-voltage wires before disconnecting. Verify primary voltage matches your supply before energizing.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before cutoff.
