OEM Carrier Control Transformer 60VA 115/208/230V for Model PH13PR048000ACAA

This OEM control transformer is the factory-authorized replacement for the Carrier PH13PR048000ACAA heat pump system. The transformer steps line voltage (115, 208, or 230V primary) down to the 24V AC that powers your thermostat, contactor coil, and all low-voltage control circuits. When this part fails, the entire control circuit goes dark — the thermostat goes blank, the system won't respond to calls for heating or cooling, and no contactors or relays will energize. It is one of the most complete single-point failure modes in any HVAC system.

• Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 / HT01AW229A
• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM unit manufactured to Carrier's exact VA rating and insulation class. Generic transformers are often under-rated for VA load, causing thermal overload trips and premature failure under full control circuit demand.
• Install difficulty: 2/5 — Shut off all power at the breaker before working on this part. Tools needed: flathead and Phillips screwdrivers, multimeter (to verify 24V output before reconnecting), wire nuts or terminals. Label all 24V control wires before disconnecting. Verify primary tap matches your supply voltage.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Direct OEM replacement for Carrier model PH13PR048000ACAA heat pump systems. The multi-tap primary (115/208/230V) makes this transformer suitable across a wide range of supply voltages — confirm your unit's data plate voltage before selecting the correct primary tap.
