OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR03000GAAAA

This is the genuine OEM factory-replacement control transformer for the Carrier PH13NR03000GAAAA heat pump system. The transformer steps down line voltage (115, 208, or 230V) to the 24V control circuit that powers your thermostat, contactor coil, reversing valve, and all low-voltage safety controls. When this transformer fails — whether from a shorted control board, a wiring fault, or simply age — the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any call for heating or cooling, and no low-voltage components will operate. Replacing it with the correct OEM part (HT01AW229) restores full factory-rated performance and protects downstream components from under-voltage stress.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount configuration | Part No. HT01AW229 / HT01AW229A
• OEM vs Generic: This factory-authorized part is wound to exact Carrier tolerances, ensuring a stable, clean 24V output. Generic or off-brand transformers often run outside the ±5% voltage tolerance, causing nuisance lockouts, contactor chatter, and premature control board failure.
• Install difficulty: 2/5 — Shut off all power to the unit before starting. Tools needed: multimeter (to verify incoming voltage tap), flat-head and Phillips screwdrivers, wire nuts or spade terminals, and a wiring diagram (located on the unit door). Always confirm the correct primary voltage tap before energizing. Photo your wiring before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier PH13NR03000GAAAA heat pump systems. The multi-tap 115/208/230V primary makes it suitable across a range of supply voltages — verify your unit's data plate supply voltage and select the correct primary tap during installation. Cross-references include HT01AW229A, CIN-TRAN, 30-BV2006, and 30-1814A. Have a fitment question?
