OEM Carrier Foot-Mounted Transformer 60VA 115/208/230V–24V for Model PH13NB01800GAAAA

This OEM Carrier transformer (part number HT01AW229) is the factory-authorized replacement for the Carrier PH13NB01800GAAAA packaged heat pump unit. The control transformer steps down the high-voltage line power (115, 208, or 230V primary) to a safe 24V AC secondary signal that powers your thermostat, contactor coil, and all low-voltage control circuitry. When it fails, the entire control circuit goes dead — the thermostat displays nothing, the contactor won't energize, and no heating or cooling is possible. Replacing a failed transformer is one of the most impactful single-component repairs you can make to restore full system operation.

  • Specs: 60VA rating | Multi-tap primary: 115V / 208V / 230V | 24V AC secondary | Foot-mounted design | Factory-matched OEM tolerances
  • OEM vs Generic: The OEM HT01AW229 is manufactured to Carrier's exact VA rating and insulation class. Generic transformers rated at nominal 60VA often run hot under full control-circuit load, shortening service life and risking nuisance fuse failures.
  • Install difficulty: 2/5 — Disconnect all power to the unit before beginning. Tools needed: multimeter (verify 24V output after install), flathead and Phillips screwdrivers, needle-nose pliers, wire nuts. Always photograph or label existing wiring before disconnecting primary and secondary leads. Confirm correct primary tap (115V, 208V, or 230V) matches your supply voltage before energizing.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PH13NB01800GAAAA packaged heat pump units. Verify supply voltage matches your selected primary tap (115V, 208V, or 230V) before installation. Cross-references: HT01AW229A. Questions about fitment? Our HVAC parts specialists confirm compatibility before you order — contact us today.

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NB01800GAAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NB01800GAAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier PH13NB01800GAAAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
