OEM Carrier 60VA Control Transformer (HT01AW229) for Model PH13PR060000ADAA

This OEM control transformer is the factory-specified replacement for the Carrier PH13PR060000ADAA heat pump. The transformer steps down high-voltage line power (115V, 208V, or 230V) to the 24V AC signal required by your thermostat, control board, contactor coil, and all low-voltage control circuits. When this component fails, the entire control circuit loses power — the thermostat goes dark, the system ignores calls for heating or cooling, and no contactors or relays will energize. A failed transformer is one of the most common reasons an HVAC system appears completely unresponsive despite having full line voltage.

• Specs: 60VA rating | Primary voltage: 115V / 208V / 230V (multi-tap) | Secondary voltage: 24V AC | OEM Part Number: HT01AW229 | Factory Authorized Carrier part
• OEM vs Generic: This is a genuine Factory Authorized Carrier part engineered to exact VA rating and insulation class. Generic transformers often run undersized VA ratings, causing premature thermal cutout trips and nuisance lockouts under full control-circuit load.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or terminal screwdriver. Confirm primary tap wiring matches your supply voltage before energizing. Always photograph existing wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH13PR060000ADAA heat pump. Verify your existing transformer's primary voltage tap and VA rating against your unit's data plate before ordering. Cross-reference part numbers: HT01AW229, HT01AW229A. Have a fitment question? Our HVAC parts specialists confirm compatibility before you buy — reach out before placing your order.
