OEM Carrier Control Transformer 60VA 115/208/230V-24V for Model PH13NR024000AFAA

This is the factory-specified OEM control transformer for the Carrier PH13NR024000AFAA heat pump system. The transformer steps down high-voltage line power (115/208/230V primary) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuitry. When this component fails, the entire control circuit goes dead — the thermostat goes blank, the system will not respond to any calls for heating or cooling, and no error codes can even be generated. It is often misdiagnosed as a board or thermostat failure, making proper identification critical before replacing other components.

• Specs: 60 VA power rating | 115/208/230V AC primary | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM Part# HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and voltage tolerances, protecting sensitive control boards. Generic units risk undervoltage conditions that cause nuisance lockouts and premature contactor coil failure.
• Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after installation). Always photograph or label existing wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for Carrier model PH13NR024000AFAA heat pump systems. Also cross-references to Bryant and Payne units sharing the same 60VA, 115/208/230V–24V transformer specification. Always confirm primary voltage, secondary voltage, and VA rating on your unit's data plate before ordering. Have a fitment question?
