OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR024000ACAA

This factory-authorized OEM control transformer is the direct replacement for the Carrier PH13NR024000ACAA heat pump. The transformer steps primary line voltage (115, 208, or 230 VAC) down to the 24 VAC signal voltage that powers the entire low-voltage control circuit — including the thermostat, contactors, reversing valve, and safety controls. When this transformer fails, the result is a completely unresponsive system: the thermostat goes blank, no relays click, and nothing starts. A blown fuse on the secondary side is often the first sign; if the fuse keeps blowing, a failed transformer is a primary suspect.

• Specs: 60 VA power rating | 115/208/230 VAC primary (multi-tap) | 24 VAC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229
• OEM vs Generic: This is a Factory Authorized Part (FAP) built to Carrier's exact VA rating and insulation class. Undersized or off-tolerance generic transformers can overheat, trip thermal cutouts prematurely, and void system warranties — especially on variable-stage heat pump platforms.
• Install difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is zero with a multimeter before touching wiring. Tools needed: multimeter, flathead and Phillips screwdrivers, needle-nose pliers. Photograph all wire connections before disconnecting. Confirm primary tap selection (115V vs 208/230V) matches your supply voltage before re-energizing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH13NR024000ACAA heat pump. The multi-tap primary (115/208/230V) makes this transformer suitable across a broad range of Carrier, Bryant, and Payne equipment sharing the same control platform. Always verify the OEM part number on the original transformer's label before ordering. Have a fitment question? Our HVAC parts team confirms compatibility before you buy — just reach out.
