OEM Carrier Control Transformer 60VA 115/208/230V — 24V Secondary for Model PH13NB018000AAAA

This is the factory-authorized OEM replacement control transformer for the Carrier PH13NB018000AAAA heat pump system. The transformer steps down high-voltage line power (115, 208, or 230V primary) to the 24V AC signal that powers your control board, thermostat wiring, and all low-voltage system components. When this transformer fails, the entire control circuit goes dark — the thermostat becomes unresponsive, the system won't start, and you may find a tripped low-voltage fuse or blown secondary. Replacing this OEM unit restores the full 60VA of clean, stable control voltage the system was designed to operate on.

  • Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount configuration | OEM part number HT01AW229
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part (FAP). OEM transformers are wound to exact VA and voltage specifications, protecting sensitive control boards from undervoltage and transient spikes. Generic alternatives may have looser tolerances, risking premature board failure.
  • Install difficulty: 3/5 — Shut off all power at the disconnect and breaker before starting. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, and needle-nose pliers. Label all 24V secondary wires before disconnecting. Verify primary tap connection matches your supply voltage — incorrect tap selection is the most common installation error.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Direct OEM fit for Carrier model PH13NB018000AAAA. Cross-references include HT01AW229A and Totaline/RCD equivalents. Always verify supply voltage and VA rating against your unit's data plate before ordering. Have a question about fitment?

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NB018000AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NB018000AAAA. 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 PH13NB018000AAAA?
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?
