OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13PR048000AHAA

This is the OEM factory-specified control transformer for the Carrier PH13PR048000AHAA heat pump system. The control transformer steps down high-voltage line power (115/208/230V primary) to the 24V AC secondary signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and control board. When this transformer fails, the system loses all low-voltage signal and nothing responds: the thermostat goes blank, the unit won't start, and no error codes appear because the board itself has no power. Replacing this transformer with the correct OEM unit (part number HT01AW229) restores the control circuit immediately.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount chassis | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: OEM transformers are wound to exact factory VA and voltage tolerances. Undersized or off-spec generic units can overheat under full control-circuit load, causing nuisance shutdowns or premature board failure — especially on larger systems like the 4-ton PH13PR048000AHAA.
• Install difficulty: 2/5 — Shut off all power to the unit before proceeding. Tools needed: screwdriver, needle-nose pliers, multimeter (to verify 24V output post-install). Label or photograph all low-voltage wiring before disconnecting. Discharge any capacitors in the panel before working near high-voltage terminals.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Directly fits Carrier model PH13PR048000AHAA heat pump systems. The multi-tap 115/208/230V primary design accommodates varying supply voltages common in residential and light commercial installations. Always verify your unit's supply voltage and VA requirement on the data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy.
