OEM Carrier Control Transformer 40VA 120V–24V for Model PH13NR06000GAAAA

This is the factory-specified OEM replacement transformer (part number HT01AW229) for the Carrier PH13NR06000GAAAA heat pump system. The transformer is the critical power-conversion component in the low-voltage control circuit — it steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, contactor coil, and all safety relays. When the transformer fails, the entire control circuit goes dark: the thermostat shows no response, the system refuses to start, and in some cases a tripped secondary fuse is the first clue. Replacing with the correct OEM unit ensures factory-matched VA capacity and coil impedance, preventing nuisance trips and premature secondary fuse failures.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory OEM part number HT01AW229 | Carrier-matched coil impedance and thermal protection
  • OEM vs Generic: OEM transformers from Carrier are wound to exact VA and voltage-regulation tolerances. Generic units often run under-rated VA capacity, causing voltage sag under full control-circuit load — which can confuse control boards and cause erratic lockouts.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching terminals and 24V output after install). Photograph all wiring connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH13NR06000GAAAA heat pump systems. Always verify your unit's data plate voltage and VA rating match before ordering. Our technical team is available to confirm fitment — just reach out before you order. Order now and ship today!
