OEM Carrier 60VA Control Transformer HT01AW229 for Model PH10PA060000AAAA

This is the OEM factory-specified control transformer for the Carrier PH10PA060000AAAA Payne 5-ton packaged heat pump unit. The control transformer steps down line voltage (115, 208, or 230 VAC) to the 24 VAC signal voltage that powers your thermostat, contactor coils, reversing valve solenoids, and all low-voltage control circuitry. When it fails, the entire control circuit goes dark — the thermostat goes blank, the unit refuses to respond to any call for heating or cooling, and no contactors energize. A failed transformer is often misdiagnosed as a bad control board; always check transformer output voltage first with a multimeter before replacing more expensive components.

• Specs: 60 VA power rating | Primary voltage: 115 / 208 / 230 VAC (multi-tap) | Secondary voltage: 24 VAC | Frequency: 50/60 Hz | Foot-mount configuration | OEM Part No. HT01AW229 / HT01AW229A
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part built to exact VA rating and insulation class. Generic transformers often drift in secondary output voltage under load, causing nuisance lockouts, erratic thermostat behavior, and premature contactor coil failure — problems that return the technician to the same job call twice.
• Install difficulty: 2/5 — Shut off all power at the disconnect before starting. Discharge any capacitors in the control box. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24 VAC output after install). Photograph all low-voltage wiring connections before removing the old transformer. The foot-mount bracket bolts directly to the existing control box chassis.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our warehouse when ordered before cutoff time.

Compatibility: Engineered as the direct OEM replacement for Carrier PH10PA060000AAAA Payne packaged heat pump units. Cross-references: HT01AW229A, CIN-TRAN, 30-BV2006, 30-1814A. Always verify primary voltage tap matches your unit's supply voltage (115V, 208V, or 230V) before installing. Questions about fitment?
