OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH10JA01800GAFAA

This is the factory OEM control transformer for the Carrier PH10JA01800GAFAA packaged HVAC unit. The transformer steps down line voltage (115, 208, or 230V primary) to the 24V AC signal that powers every component in your control circuit — thermostat, contactor coil, gas valve, and control board. When this transformer fails, nothing works: no heating, no cooling, no response from the thermostat. A failed transformer is often accompanied by a tripped circuit breaker on the secondary side or a completely dead control panel with no indicator lights.

• Specs: 60 VA rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | Foot-mounted configuration | OEM Part # HT01AW229 | Also sold as HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound to exact VA and impedance specs for the PH10JA01800GAFAA control circuit. Undersized or off-spec generic transformers can overheat, blow secondary fuses, and damage downstream boards.
• Install difficulty: 3/5 — Shut off all power at the disconnect before starting. Tools needed: multimeter (verify 0V before touching leads), flathead and Phillips screwdrivers, wire stripper, needle-nose pliers. Always label wires before disconnecting. Check and replace any blown 3A or 5A secondary fuse before energizing the new transformer.
• Warranty: 1-year OEM Carrier factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed and factory-specified for the Carrier PH10JA01800GAFAA packaged unit. Verify your existing transformer's VA rating and primary voltage tap before ordering — mismatched VA ratings will cause premature failure.
