OEM Carrier 60VA Control Transformer HT01AW229 for Model PH10PA060000ABAA

This OEM control transformer is the factory-specified replacement for the Carrier PH10PA060000ABAA packaged heat pump unit. The transformer steps down high-voltage line power (115/208/230V) to the 24V signal voltage that powers the control board, thermostat circuit, contactor coil, and all low-voltage switching logic. When it fails — or its internal thermal overload trips — the entire control circuit goes dark: the thermostat displays nothing, the system refuses to start, and relays won't energize. This is one of the first parts to check in a complete no-response scenario.

• Specs: 60 VA power rating | Primary voltage: 115/208/230 VAC multi-tap | Secondary voltage: 24 VAC | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and impedance specs, include integrated thermal overload protection, and are matched to the PH10PA control board's inrush requirements. Off-brand units often underrate VA, causing nuisance overloads and premature burnout.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, multimeter (to confirm 0V before touching terminals), wire stripper, needle-nose pliers. Label all low-voltage wires before disconnecting. Verify primary tap matches your supply voltage.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PH10PA060000ABAA packaged heat pump. Also cross-references to HT01AW229A. Confirm your unit's supply voltage (115V, 208V, or 230V) and select the correct primary tap on installation. Questions about fitment?
