OEM Carrier Control Transformer 60VA 115/208/230V for Model PH13NR04800GAFAA

This is the factory OEM control transformer (part #HT01AW229) specified for the Carrier PH13NR04800GAFAA heat pump system. The control transformer steps down high-voltage line power (115/208/230V primary) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control circuitry. When this transformer fails, the entire control circuit goes dark — the thermostat loses power, the system won't respond to calls for heating or cooling, and no safety controls can operate. It is often the first component to check when nothing works at all.

• Specs: 60 VA rating | Primary: 115/208/230V AC | Secondary: 24V AC | Foot-mounted chassis | OEM part #HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact VA and voltage tolerances. Generic transformers often run undersized VA ratings, causing overheating, nuisance tripping, or premature failure under multi-zone or multi-accessory load.
• Install difficulty: 2/5 — Shut off all power to the unit at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all low-voltage wires before disconnecting from the old transformer. Verify primary voltage tap matches your supply voltage (115V or 208/230V) before energizing.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse — order by 3PM local time.

Compatibility: Designed as the factory-specified replacement for Carrier model PH13NR04800GAFAA. Cross-references include HT01AW229A.
