OEM Carrier Control Transformer 60VA 115/208/230V-24V for Model PH13NR04200GAEAA

This OEM control transformer (part# HT01AW229) is the factory-specified replacement for the Carrier PH13NR04200GAEAA heat pump system. The transformer steps down high-voltage primary power (115/208/230 VAC) to the 24 VAC control circuit voltage that powers your thermostat, contactor coil, and all low-voltage safety controls. When this transformer fails, the entire control circuit goes dead — the thermostat loses power, the system won't respond to calls for heating or cooling, and there is no 24V present at the control board. A failed transformer is a common root cause of a system that appears completely unresponsive.

• Specs: 60 VA power rating | 115/208/230 VAC primary voltage | 24 VAC secondary voltage | 50/60 Hz | Foot-mount configuration | Factory-matched OEM part number HT01AW229
• OEM vs Generic: OEM transformers are wound and rated to exact factory VA tolerance, ensuring the control circuit isn't starved under peak demand (multiple zone valves, economizers, or accessory loads). Undersized or out-of-spec generic transformers can cause nuisance tripping of the internal thermal fuse, putting you right back to square one.
• Install difficulty: 2/5 — Disconnect all power before working on the transformer. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Confirm 24 VAC output before re-energizing the full system. Always photograph or label wire connections prior to removal.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM drop-in replacement for the Carrier PH13NR04200GAEAA heat pump. Also cross-references as HT01AW229A. Verify primary voltage tap matches your unit's supply voltage (115V, 208V, or 230V) before wiring. Questions about fitment?
