OEM Carrier 60VA Control Transformer 115/208/230V-24V for Model PH13NR04800GAKAA

This OEM control transformer is the factory-specified replacement for the Carrier PH13NR04800GAKAA heat pump system, supplied under Carrier part number HT01AW229. The transformer steps down incoming line voltage to the 24V AC signal that powers the entire control circuit — including the thermostat, contactor coil, and safety switches. When this transformer fails, nothing works: the thermostat goes dark, the system will not respond to any call for heating or cooling, and you may measure 0V on the secondary (24V) side despite normal line voltage present at the primary.

• Specs: 60VA rated | Primary voltage: 115V / 208V / 230V (multi-tap) | Secondary output: 24V AC | Factory-matched OEM tolerances for the PH13NR04800GAKAA platform
• OEM vs Generic: This is a genuine OEM Carrier part meeting exact factory VA rating and insulation class. Undersized or off-spec generic transformers can overheat, trip internal thermal fuses prematurely, and void equipment warranties.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, needle-nose pliers, wire nuts or spade connectors. Confirm 0V on both primary and secondary before touching terminals. Photograph all wiring connections before disconnecting the old transformer.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM drop-in replacement for Carrier model PH13NR04800GAKAA. Also fits Carrier, Bryant, and Payne equipment sharing the HT01AW229 transformer specification. Always verify your existing transformer's VA rating and voltage taps on the unit data plate before ordering. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy.
