OEM Carrier Control Transformer 60VA 115/208/230V – 24V for Model PH13PR06000GAJAA

This is the factory-authorized OEM control transformer for the Carrier PH13PR06000GAJAA packaged heat pump system. The control transformer steps down high-voltage line power (115, 208, or 230V primary) to a safe 24V AC signal that energizes the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and safety switches. When this transformer fails, the entire system goes silent: no thermostat response, no contactor pull-in, and no operation whatsoever. It is often misdiagnosed as a control board or thermostat failure, making it one of the first components to check during a no-power service call.

• 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
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP), manufactured to exact OEM tolerances. Generic transformers often use thinner gauge windings and lower-grade core laminations, leading to premature thermal failure — especially under high-VA demand from multiple simultaneous control loads.
• Install difficulty: 2/5 — Always shut off power at the disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter (to verify 24V output after install), wire stripper, and needle-nose pliers. Confirm primary tap wiring matches your supply voltage (115V, 208V, or 230V) before energizing. Label wires before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.
