OEM Carrier 60VA Control Transformer HT01AW229 for Model PH13PR048000AAAA

This is the genuine OEM factory replacement control transformer for the Carrier PH13PR048000AAAA heat pump system. The transformer steps down line voltage (115/208/230V primary) to the 24V secondary signal used to power the control board, thermostat circuit, and all low-voltage system controls. When this transformer fails, your system will appear completely unresponsive — the thermostat goes dark, contactors won't pull in, and no heating or cooling cycle can initiate. A burnt smell near the air handler or a tripped fuse on the control board is a common accompanying symptom.

• Specs: 60VA rating | 115/208/230V primary input | 24V secondary output | OEM Part Number: HT01AW229 | Factory-matched impedance and thermal protection
• OEM vs Generic: The OEM HT01AW229 is wound to exact Carrier factory tolerances with built-in thermal overload protection. Generic transformers often lack proper VA headroom, causing nuisance fuse trips and premature failure under multi-zone or communicating thermostat loads.
• Install difficulty: 2/5 — Shut off all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label or photograph all low-voltage wiring before disconnecting. Verify primary 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 and factory-specified for the Carrier PH13PR048000AAAA heat pump. Cross-references include HT01AW229A. Always confirm your unit's supply voltage and VA requirements on the equipment data plate before ordering. Our fitment team is available to verify compatibility before you buy — no guesswork required.
