OEM Carrier 60VA Control Transformer HT01AW229 for Model PH13NR02400GAAAA

This is the factory-authorized OEM control transformer (part number HT01AW229) for the Carrier PH13NR02400GAAAA heat pump system. The control transformer steps down high-voltage line power (115/208/230VAC) to the safe 24VAC signal used by thermostats, contactors, and all low-voltage control circuits. When this transformer fails, the entire control circuit loses power — the thermostat goes blank, the system refuses any commands, and you may hear a faint buzz or hum from the transformer housing. Replacing it restores full system operation.

• Specs: 60VA power rating | 115/208/230 VAC primary (multi-tap) | 24 VAC secondary | 50/60 Hz | Foot-mount style | OEM part number HT01AW229
• OEM vs Generic: OEM transformers are wound to exact Carrier factory tolerances, ensuring stable 24V output under full load. Off-brand units often deliver inconsistent voltage, leading to nuisance lockouts, contactor chatter, and shortened control board life.
• Install difficulty: 3/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to verify 0V before touching terminals and 24VAC output after). Always label and photograph existing wiring before disconnecting. Foot-mount style may require bracket removal.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: This transformer is the OEM-specified replacement for the Carrier PH13NR02400GAAAA heat pump. Also cross-references for select Bryant and Payne units using the same 60VA, 115/208/230V–24V specification. Always verify your unit's data plate voltage requirements match before installing.
