OEM Carrier 60VA Control Transformer (HT01AW229) for Model PH13NR060000AFAA

This is the genuine OEM factory-replacement control transformer for the Carrier PH13NR060000AFAA packaged heat pump unit. The transformer steps down the 115/208/230V line voltage to a safe 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and any connected zone controls. When this transformer fails, the entire control circuit goes dead: the thermostat loses power, the system will not respond to any heating or cooling call, and you may measure 0V across the 24V secondary terminals. A blown internal fuse or shorted secondary winding are the most common failure modes.

• Specs: 60 VA power rating | Primary voltage: 115/208/230 VAC (multi-tap) | Secondary voltage: 24 VAC | 50/60 Hz | Foot-mount configuration | OEM Part# HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM transformers are wound to exact VA and impedance specs, protecting downstream controls from voltage sag under full load. Generic 60VA transformers often run hot and trip their thermal cutout prematurely in high-ambient equipment rooms.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (verify 0V before touching terminals). Photograph or label all low-voltage wiring before disconnecting. Verify primary tap matches your supply voltage (115V or 208/230V) before energizing.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NR060000AFAA packaged heat pump. The multi-tap primary (115/208/230V) makes this transformer adaptable to a range of supply voltages — always confirm your supply voltage matches the selected tap before installation.
