OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH10JA02400GAFAA

This is the factory OEM replacement control transformer for the Carrier PH10JA02400GAFAA packaged unit. The transformer steps down high-voltage primary power (115, 208, or 230V) to a safe 24V secondary signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the result is total control circuit loss: the thermostat goes blank, the unit won't respond to calls for heating or cooling, and no low-voltage components operate. A shorted secondary or open primary winding is one of the most common causes of an otherwise unexplained "dead" HVAC system.

• Specs: 60VA rating | Primary: 115 / 208 / 230V multi-tap | Secondary: 24V | Foot-mounted configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. Generic transformers often use undersized cores that overheat under continuous load, causing nuisance failures and potential control board damage. OEM ensures exact VA rating, proper insulation class, and factory-matched mounting footprint.
• Install Difficulty: 2/5 — Shut off all power to the unit before beginning. Photograph or label all wire connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after installation). Verify primary tap selection matches your supply voltage before energizing.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
