OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NB04800GABAA

This OEM control transformer is the factory-specified replacement for the Carrier PH13NB04800GABAA heat pump system. The transformer steps down line voltage (115, 208, or 230V primary) to the 24V AC signal that powers your thermostat, contactor coil, control board, and all low-voltage safety circuits. When this transformer fails, the entire control circuit goes dead — your thermostat goes blank, the system refuses to respond to any call for heating or cooling, and you may blow a 24V fuse repeatedly. If your unit shows zero response despite power being present at the disconnect, a failed transformer is one of the first components to test.

  • Specs: 60VA 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 Factory Authorized Parts (FAP) OEM unit built to Carrier's exact VA rating and insulation class. Generic transformers may be under-rated in VA, causing thermal overload and premature failure under full control-circuit load — especially on systems with zone boards or electronic air cleaners drawing additional VA.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and outdoor disconnect before working on any transformer. Tools needed: multimeter, flathead and Phillips screwdrivers, wire nuts or terminal connectors. Verify primary tap wiring matches your actual line voltage (208V vs. 230V) before energizing. Photograph all wire connections before disconnecting.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH13NB04800GABAA packaged heat pump unit. The multi-tap primary (115/208/230V) makes this transformer suitable across a range of Carrier, Bryant, and Payne platforms — always confirm the VA rating and mounting style against your unit's data plate before ordering. Our fitment team is available to verify compatibility before you buy.

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NB04800GABAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NB04800GABAA. 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 PH13NB04800GABAA?
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?
