OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH13NR03600GAEAA

This is the genuine OEM factory-authorized control transformer for the Carrier PH13NR03600GAEAA heat pump system. Part number HT01AW229, this foot-mounted step-down transformer converts 115/208/230V line voltage to the 24V signal required to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the entire low-voltage control system goes dark: the thermostat loses power, the system won't respond to calls for heating or cooling, and in some cases the blower won't operate at all. A failed transformer is often indicated by a blown 3A fuse on the control board or a complete loss of thermostat display.

  • Specs: 60 VA rating | Primary voltage: 115/208/230V multi-tap | Secondary voltage: 24V AC | Foot-mount configuration | OEM part number HT01AW229 (also referenced as HT01AW229A)
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM transformers are wound to exact VA tolerance, ensuring the 24V control circuit holds voltage under peak load. Generic transformers often under-deliver VA capacity, causing nuisance fuse failures and erratic system behavior.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter (to verify 24V output post-install), wire nuts or spade terminals. Photograph all wiring connections before disconnecting. Verify primary tap matches your supply voltage before energizing.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse. Genuine Carrier Factory Authorized Part.

Compatibility: Direct OEM replacement for Carrier model PH13NR03600GAEAA. Also cross-references as HT01AW229A. Confirm your unit's supply voltage matches one of the primary taps (115V, 208V, or 230V) before ordering. Need help verifying fitment? Our HVAC parts specialists confirm compatibility before you buy — order with confidence and get this part shipped to your door today.

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NR03600GAEAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NR03600GAEAA. 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 PH13NR03600GAEAA?
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?
