OEM Carrier Control Transformer 40VA 120V/24V for Model HP13PR03600GAKAA

This is the OEM factory-specified control transformer (part number HT01AW229) for the Carrier HP13PR03600GAKAA heat pump system. The transformer steps down line voltage from 120V to the 24V AC signal that powers your thermostat, control board, and all low-voltage switching components. When this part fails, the entire control circuit goes dark — the thermostat display may go blank, the system won't respond to any calls for heating or cooling, and in some cases a tripped secondary fuse is the only clue pointing back to a shorted transformer.

  • Specs: 40VA rated | Primary: 120V | Secondary: 24V AC | OEM part number HT01AW229 | Factory-matched to Carrier HP13PR03600GAKAA control circuit requirements
  • OEM vs Generic: The OEM transformer is wound to exact VA and voltage tolerances required by the Carrier control board. Undersized or off-tolerance generic units can overheat quickly, blow secondary fuses repeatedly, or damage downstream boards and thermostats.
  • Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Label all wiring before removing the old transformer. The secondary fuse should also be inspected and replaced if blown.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier HP13PR03600GAKAA heat pump. Always verify your unit's data plate and existing transformer VA/voltage ratings before ordering. If you're unsure of fitment, our HVAC parts specialists are available to confirm compatibility before you buy — same-day shipping available on all in-stock orders.

Frequently Asked Questions

Does this Transformer fit my Carrier HP13PR03600GAKAA?
Yes. This is the factory-specified OEM transformer for the Carrier HP13PR03600GAKAA. 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 HP13PR03600GAKAA?
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?
