OEM Carrier Control Transformer 60VA 115/208/230V — 24V Secondary for Model PH13NB06000GABAA

This OEM control transformer (part number HT01AW229) is the factory-specified replacement for the Carrier PH13NB06000GABAA heat pump system. The transformer steps down high-voltage primary power (115, 208, or 230V) to the 24V AC signal that energizes your thermostat, contactor coil, and all low-voltage control logic. When this transformer fails, the entire control circuit goes dead — the thermostat loses power, the system will not respond to any calls for heating or cooling, and in some cases a tripped internal fuse or breaker is the only symptom. Replacing it with the correct OEM unit restores factory-rated performance and protects downstream components from voltage irregularities.

• Specs: 60VA power rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and voltage tolerances. Undersized or off-tolerance generic units can overheat, trip repeatedly, or cause erratic low-voltage control behavior — shortening the life of your control board and contactor.
• Install difficulty: 3/5 — Disconnect and lock out all power before beginning. Tools needed: multimeter (verify 0V before touching wiring), flathead and Phillips screwdrivers, wire nuts or spade connectors. Photograph all wiring before removal. Verify primary voltage tap matches your supply voltage (115V, 208V, or 230V) before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NB06000GABAA heat pump. Also used across compatible Carrier, Bryant, and Payne equipment sharing the HT01AW229 specification. Always confirm your unit's primary supply voltage and VA requirement against your data plate before ordering. Have fitment questions? Our HVAC parts specialists verify compatibility before you buy.
