OEM Carrier 60VA Control Transformer HT01AW229 for Model PH12NA04800GADAA

This is the OEM factory-authorized replacement control transformer for the Carrier PH12NA04800GADAA packaged heat pump unit. The transformer steps high-voltage primary power (115/208/230V AC) down to the 24V AC signal that powers your thermostat, control board, contactor coil, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dark — the thermostat goes blank, the system will not respond to any calls for heating or cooling, and in some cases a burning smell or tripped fuse may indicate transformer failure.

• Specs: 60 VA power rating | 115/208/230V AC primary | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229
• OEM vs Generic: This is a genuine Factory Authorized Parts (FAP) transformer, precision-wound to Carrier's exact VA rating and insulation class. Generic transformers frequently run at lower actual VA output, causing overheating and nuisance tripping of the internal fuse or thermal cutout under normal load conditions.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before proceeding. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter, needle-nose pliers. Label all low-voltage wiring connections before removal. Verify primary voltage tap matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our climate-controlled warehouse.

Compatibility: Engineered for the Carrier PH12NA04800GADAA packaged heat pump unit. Also fits select Bryant and Payne models sharing the same 60VA 115/208/230V-24V transformer specification — verify your unit's data plate primary voltage and VA rating before ordering. Our technical team is available to confirm fitment prior to purchase.
