OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR02400GAFAA

This is the factory OEM replacement control transformer for the Carrier PH13NR02400GAFAA heat pump system. The transformer steps high-voltage line power (115, 208, or 230V AC) down to the 24V AC signal required by your thermostat, control board, contactor coil, and all low-voltage safety circuits. When this transformer fails — due to a shorted control wire, failed board, or age — the entire low-voltage control circuit goes dead: the thermostat goes blank, the system won't respond to any call for heating or cooling, and the unit sits completely unresponsive. Replacing the transformer is typically the first diagnostic step after ruling out a blown fuse on the control board.

• Specs: 60VA power rating | 115/208/230V AC primary | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)
• OEM vs Generic: This is a Factory Authorized Part manufactured to Carrier's exact VA rating and voltage tolerance. Generic transformers are often under-rated in VA capacity, causing premature thermal cutout failure, especially on systems with multiple 24V accessories like zone boards or humidifiers.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all wires before removal. Confirm the old transformer's VA and voltage ratings match before installing.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.
