OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NA02400GABAA

This is the OEM factory-specified control transformer for the Carrier PH13NA02400GABAA packaged heat pump unit. The transformer steps down the high-voltage supply (115, 208, or 230V primary) to a safe 24V secondary signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and all safety safeties. When this transformer fails, nothing in the system responds: the thermostat goes blank, the unit will not start, and there is no 24V at the control board. Replacing a faulty transformer immediately restores the entire control circuit.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount configuration | Part number HT01AW229 / HT01AW229A
• OEM vs Generic: OEM transformers are precision-wound to Carrier's exact VA rating and insulation class, preventing voltage sag under high control-circuit loads. Undersized or off-brand transformers risk overheating, nuisance tripping, and control board damage.
• Install difficulty: 2/5 — Disconnect all power before servicing. Tools needed: multimeter (verify 0V before touching wires), flathead and Phillips screwdrivers, wire nuts or spade terminals. Confirm primary tap matches your supply voltage before energizing. Always photograph existing wiring before removal.
• Warranty: 1-year OEM factory warranty on parts and materials. In-stock units ship same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PH13NA02400GABAA packaged heat pump units. Also cross-references as HT01AW229A and is used across Carrier, Bryant, and Payne platforms sharing the 60VA 115/208/230V–24V transformer specification. Always verify your unit's data plate voltage and VA rating before ordering. Our fitment team is available to confirm compatibility prior to purchase.
