OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13PR04800GAKAA

This is the genuine OEM factory-authorized control transformer for the Carrier PH13PR04800GAKAA packaged heat pump unit. Part number HT01AW229, this foot-mounted transformer steps down line voltage (115, 208, or 230V primary) to a stable 24V AC secondary at 60VA — powering the entire low-voltage control circuit including the thermostat, contactor coil, and safety switches. When this transformer fails, the result is a completely unresponsive system: no thermostat response, no fan, no heating or cooling. A blown fuse on the secondary side, a burning smell near the air handler, or 0V measured at the 24V terminals are the classic signs of transformer failure.

• Specs: 60 VA power rating | Primary voltage: 115 / 208 / 230 VAC | Secondary voltage: 24 VAC | Foot-mount configuration | 50/60 Hz | Part No. HT01AW229 (also cross-references HT01AW229A)
• OEM vs Generic: OEM transformers are wound and insulated to Carrier's exact factory specifications, ensuring the correct VA headroom for all connected loads. Undersized or off-spec generic units may overheat, blow secondary fuses repeatedly, or damage connected control boards.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: multimeter, Phillips and flathead screwdrivers, wire stripper. Always verify 0V at terminals before touching wiring. Label or photograph all low-voltage wiring connections prior to removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model PH13PR04800GAKAA packaged heat pump units. Verify primary voltage matches your unit's data plate (115V, 208V, or 230V) and confirm 60VA rating before ordering. Cross-references: HT01AW229A. Questions about fitment?
