OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH10JA03600GAHAA

This is the genuine OEM factory-authorized control transformer for the Carrier PH10JA03600GAHAA packaged HVAC unit. Part number HT01AW229, this foot-mounted 60VA transformer steps down line voltage (115V, 208V, or 230V primary) to the 24V AC used by your thermostat, control board, gas valve, and all low-voltage control circuitry. When the transformer fails, the entire 24V control circuit goes dead — the system will not respond to the thermostat, the contactor will not energize, and no heating or cooling function will operate. A failed transformer is often indicated by a blown fuse on the control board or a completely unresponsive system despite line voltage being present.

• Specs: 60VA rating | Primary voltage: 115V / 208V / 230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | OEM Part #HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact VA and voltage specifications. Off-brand transformers frequently run undersized VA ratings that overheat under full control-circuit load, causing nuisance fuse failures and premature board damage.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Photograph all wiring connections before disconnecting. Verify primary tap selection matches your supply voltage (115V, 208V, or 230V) before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
