OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR02400GAKAA

This is the genuine OEM factory-authorized control transformer for the Carrier PH13NR02400GAKAA heat pump system. The control transformer steps down high-voltage line power (115, 208, or 230V primary) to the 24V AC signal voltage 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 refuses to start, and no low-voltage functions respond. A failed transformer is often the single cause behind what appears to be a total system failure, making it one of the most important diagnostic parts to check.

• Specs: 60VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount chassis | OEM Part Number: HT01AW229
• OEM vs Generic: This Factory Authorized Part is wound to exact Carrier specifications, ensuring precise 24V output under full VA load. Undersized or off-tolerance generic transformers can starve contactor coils and cause erratic lockouts, especially on 60VA-demand systems.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, and needle-nose pliers. Label all low-voltage wires before disconnecting. Verify primary tap matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered by 3PM local time.

Compatibility: Designed for the Carrier PH13NR02400GAKAA heat pump. Also fits select Bryant and Payne models using the HT01AW229 or HT01AW229A specification. Always verify your unit's data plate voltage and VA rating before ordering. Our parts team is available to confirm fitment — just reach out before you buy.
