OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH13NR03600GACAA

This is the genuine OEM Carrier foot-mounted control transformer (part number HT01AW229), the factory-specified replacement for the Carrier PH13NR03600GACAA heat pump system. The control transformer steps line voltage down from 115/208/230V primary to a safe 24V secondary, powering the entire low-voltage control circuit — thermostat, contactor coil, control board, and all safety switches. When this transformer fails, nothing in the system responds: the thermostat goes blank, the contactor won't pull in, and the unit will not start at all. If you're measuring 0V at the R and C terminals of your control board, a failed transformer is the most common cause.

  • Specs: 60VA capacity | Primary voltage: 115 / 208 / 230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | Factory-matched to Carrier PH13NR03600GACAA
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances. Undersized or off-tolerance generic units can overheat, trip internal fuses, and fail prematurely — leaving you back at square one. This is the same part Carrier installs at the factory.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: multimeter (verify 0V before touching wires), flathead and Phillips screwdrivers, needle-nose pliers. Photograph all wire connections before removal. Discharge any capacitors in the cabinet before reaching across terminals.
  • Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NR03600GACAA heat pump. Cross-references: HT01AW229A. Verify your unit's data plate primary voltage tap (115V, 208V, or 230V) matches your supply voltage before installation. Not sure it fits?

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NR03600GACAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NR03600GACAA. 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 PH13NR03600GACAA?
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?
