OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR060000ADAA

This is the factory OEM replacement control transformer for the Carrier PH13NR060000ADAA heat pump system. The control transformer steps line voltage (115, 208, or 230V) down to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuits. When this transformer fails, the result is a completely unresponsive system — no thermostat display, no contactor engagement, and no heating or cooling operation. If your system is completely dead with line voltage confirmed at the unit, this transformer is the first component to test.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)
• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM transformer wound to exact Carrier specifications. Generic transformers often use undersized wire gauges and lower-grade laminate cores, leading to thermal overload and premature failure — especially in high-demand 60VA applications like this one.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Photograph all low-voltage wiring connections before disconnecting. Secure foot-mount bracket to equipment chassis before reconnecting wires.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered and factory-specified for the Carrier PH13NR060000ADAA heat pump system. The multi-tap primary (115/208/230V) makes this transformer compatible across a range of supply voltages — confirm your unit's data plate voltage before ordering. Cross-references include HT01AW229A.
