OEM Carrier Transformer 24V Control Circuit for Model PH13PR060000AFAA

This is the factory OEM replacement transformer (part number HT01AW229) for the Carrier PH13PR060000AFAA packaged heat pump unit. The transformer steps down line voltage (typically 120V or 208/240V) to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, reversing valve, and control board. When this transformer fails, the system will be completely unresponsive: the thermostat goes dark or blank, no relays energize, and neither heating nor cooling will initiate regardless of thermostat input.

• Specs: 24V secondary output | Factory-rated VA for Carrier PH13PR060000AFAA | Direct OEM replacement for part number HT01AW229 | Matches original mounting footprint and terminal configuration
• OEM vs Generic: This is the genuine Carrier OEM part, manufactured to exact VA and insulation ratings. Generic transformers frequently run at marginal VA capacity, causing nuisance tripping of the secondary fuse under normal load or premature failure of the control board.
• Install difficulty: 2/5 — Shut off all power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Label and photograph all low-voltage wiring before disconnecting. Verify 24V output at secondary terminals before restoring full system operation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
