OEM Carrier Control Transformer 60VA 115/208/230V — HT01AW229 for Model PH13NA042000ABAA

This is the genuine OEM Carrier foot-mounted control transformer (part number HT01AW229), the factory-specified replacement for the Carrier PH13NA042000ABAA heat pump system. The control transformer steps down high-voltage power (115V, 208V, or 230V primary) to the 24V secondary signal voltage that powers your thermostat, contactor coil, and all low-voltage control logic. When this transformer fails, the entire control circuit goes dead — the thermostat loses power, the system won't respond to any calls for heating or cooling, and you may find a blown 3A or 5A fuse on the control board as a secondary symptom.

  • Specs: 60 VA rated | Primary voltage: 115 / 208 / 230 VAC, 60 Hz | Secondary voltage: 24 VAC | Foot-mount configuration | OEM part number HT01AW229 (also supersedes HT01AW229A)
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part manufactured to exact VA and voltage tolerance specifications. Generic transformers often deviate in secondary voltage output under load, causing nuisance lockouts, erratic thermostat behavior, or premature contactor coil failure. OEM is the only safe choice for this application.
  • Install difficulty: 2/5 — Shut off all power to the unit at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Label or photograph all low-voltage wiring before disconnecting. Discharge any capacitors present before working inside the cabinet.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Packed securely to prevent transit damage.

Compatibility: Direct OEM replacement for Carrier model PH13NA042000ABAA heat pump systems. The multi-tap primary (115/208/230V) makes this transformer suitable across varying supply voltage configurations. Always verify the VA rating and mounting style on your unit's data plate before ordering. Not sure it fits? Contact our HVAC parts specialists — we verify fitment before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NA042000ABAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NA042000ABAA. 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 PH13NA042000ABAA?
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?
