OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NB03600GAAAA

This is the genuine OEM foot-mounted control transformer for the Carrier PH13NB03600GAAAA packaged heat pump unit, factory part number HT01AW229. The transformer steps down high-voltage supply power (115, 208, or 230V) to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coils, and control board. When this transformer fails, the result is total loss of 24V control voltage: the system will not respond to thermostat calls, the contactor won't energize, and the unit will appear completely dead despite line voltage being present at the unit.

• Specs: 60 VA rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | Foot-mounted design | Factory OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM transformers are wound and insulated to factory specifications, ensuring proper VA output under load without thermal drift or premature failure common to off-brand units.
• Install difficulty: 2/5 — Disconnect all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all low-voltage wiring before disconnecting from secondary terminals. The foot-mount bracket fastens directly to the blower deck or control panel.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct factory replacement for Carrier PH13NB03600GAAAA packaged heat pump units. Always verify your unit's data plate voltage before ordering to confirm primary tap selection (115V, 208V, or 230V). Have questions about fitment?
