OEM Carrier Control Transformer 60VA 115/208/230V — 24V Secondary for Model PH13NB036000AAAA

This is the OEM factory-specified control transformer (part number HT01AW229) for the Carrier PH13NB036000AAAA heat pump system. The transformer steps down line voltage (115, 208, or 230V AC primary) to a safe 24V AC secondary signal that powers the entire low-voltage control circuit — including the thermostat, contactor coil, and any safety switches. When this transformer fails, nothing works: the thermostat goes dark, the system is completely unresponsive, and a multimeter on the secondary will read 0V instead of the expected 24V. A blown transformer is often the result of a wiring short or a failed contactor coil drawing excess current — always identify and correct the root cause before installing the replacement.

  • Specs: 60 VA power rating | Primary voltage: 115 / 208 / 230 VAC (multi-tap) | Secondary voltage: 24 VAC | Frequency: 50/60 Hz | Foot-mounted configuration | OEM part number: HT01AW229 / HT01AW229A
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM transformers are wound to exact VA and voltage tolerances for the PH13NB036000AAAA's control circuit demand. Undersized or off-tolerance generic units can overheat, trip thermal protection, or cause nuisance lockouts under peak control-circuit load.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter. Label and photograph all low-voltage wiring before disconnecting. Verify 24V output with a multimeter before closing the panel.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PH13NB036000AAAA heat pump. Also cross-references as HT01AW229A. Verify your unit's data plate primary voltage tap requirement (115V, 208V, or 230V) before wiring. If you have any questions about fitment, our HVAC parts specialists are available to confirm compatibility before you order — don't guess on a control circuit component.

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NB036000AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NB036000AAAA. 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 PH13NB036000AAAA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
