OEM Carrier Control Transformer 60VA 115/208/230V-24V for Model PH10JA024000AHAA

This is the OEM factory-specified control transformer for the Carrier PH10JA024000AHAA packaged heat pump unit. The transformer steps down the high-voltage supply (115V, 208V, or 230V primary) to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control components. When this transformer fails, the entire control circuit goes dead — the thermostat becomes unresponsive, the unit won't energize on any call for heating or cooling, and you may find a blown 3A or 5A fuse on the control board as a secondary symptom.

• Specs: 60VA power rating | 115/208/230V AC primary | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound to exact VA and voltage tolerances, protecting sensitive control boards from under- or over-voltage. Generic replacements often run outside rated tolerances and can introduce nuisance tripping or board damage.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box and verify zero voltage with a multimeter before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or terminals. Label all 24V secondary wires before disconnecting. Replace any blown fuse in-circuit after installation.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered by 3 PM local time.
