OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NB024000AAAA

This is the factory-authorized OEM control transformer for the Carrier PH13NB024000AAAA heat pump system. The transformer steps down high-voltage line power (115, 208, or 230V) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuitry. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to any call for heating or cooling, and circuit breakers or fuses in the low-voltage loop may blow repeatedly. Replacing it with the correct OEM unit restores factory-specified voltage regulation and ensures reliable protection of downstream components.

• Specs: 60VA power rating | 115/208/230V AC primary | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM Part Number: HT01AW229
• OEM vs Generic: This factory-authorized part meets Carrier's exact VA rating and insulation class. Undersized or off-brand transformers can run hot, trip thermal protection, or deliver insufficient voltage to the contactor coil — causing nuisance lockouts and premature component wear.
• Install difficulty: 3/5 — Requires disconnecting line-voltage wiring. Always shut off power at the disconnect and verify with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, multimeter, wire stripper, needle-nose pliers. Label all wires before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct factory replacement for Carrier PH13NB024000AAAA heat pump systems. Also fits Bryant and Payne models using the HT01AW229 / HT01AW229A specification. Always verify your unit's data plate voltage requirements match the 115/208/230V primary before ordering. Have a fitment question?
