OEM Carrier 60VA Control Transformer 115/208/230V–24V for Model PH13NA03000GABAA

This is the genuine OEM factory-replacement control transformer for the Carrier PH13NA03000GABAA heat pump. The transformer steps down the 115/208/230V line voltage to the 24V signal voltage that powers every low-voltage control circuit in the system — including the thermostat, contactor coil, and control board. When this part fails, the entire control circuit goes dark: the thermostat displays nothing, the system won't respond to calls for heating or cooling, and in some cases the secondary fuse on the control board will blow repeatedly as the failing transformer draws excess current.

• Specs: 60VA rating | Primary: 115/208/230V multi-tap | Secondary: 24V output | OEM Part Number: HT01AW229 | Also cross-references HT01AW229A
• OEM vs Generic: This is the genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound to exact VA and impedance specs, protecting downstream control boards and thermostats from voltage irregularities that off-brand units can introduce.
• Install difficulty: 2/5 — Disconnect all power before servicing. Tools needed: multimeter, flathead and Phillips screwdrivers, needle-nose pliers, wire nuts or spade connectors. Verify the correct multi-tap primary lead (115V or 208/230V) matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PH13NA03000GABAA heat pump. Always confirm supply voltage and VA rating against your unit's data plate before ordering. Our team is available to verify fitment — contact us before you buy for total peace of mind.
