OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH10JA03600GAGAA

This OEM Carrier control transformer (part number HT01AW229) is the factory-specified replacement for the Carrier PH10JA03600GAGAA packaged heat pump unit. The transformer steps down line voltage (115, 208, or 230V primary) to a safe 24V secondary to power the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this part fails, the result is total loss of system response: the thermostat goes blank, no call for heating or cooling is answered, and the unit sits completely dead despite line voltage being present at the disconnect.

• Specs: 60VA power rating | 115/208/230V multi-tap primary | 24VAC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Factory Authorized Carrier part, wound to exact VA and voltage tolerances. Undersized or off-tolerance aftermarket transformers can overheat, trip thermal cutoffs prematurely, or starve contactor coils — shortening system life and causing nuisance lockouts.
• Install difficulty: 3/5 — Always disconnect power at the breaker and verify voltage is absent before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a non-contact voltage tester, and a multimeter. Note existing wire connections and primary tap selection before removing the old transformer. Tap selection must match your supply voltage to avoid damage.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.
