OEM Carrier Control Transformer 40VA 120V–24V for Model PG9MAA060100ACKA

This OEM control transformer is the factory-specified replacement for the Carrier PG9MAA060100ACKA gas furnace. The transformer steps down the 120V line-voltage supply to the 24V signal used by your thermostat, control board, gas valve, and every other low-voltage component in the system. When it fails, the result is total loss of control-circuit power — the thermostat goes dark, the furnace will not respond to any call for heat or cool, and nothing downstream operates. Replacing the transformer is one of the most cost-effective furnace repairs available.

  • Specs: Primary Voltage: 120 VAC | Secondary Voltage: 24 VAC | VA Rating: 40VA | Frequency: 50/60 Hz | Single Phase | Wire-lead connections
  • OEM vs Generic: This is a genuine OEM-specified transformer wound to exact VA and voltage tolerances. Off-brand units frequently run under-rated VA, which causes nuisance tripping of the furnace's 3A fuse and accelerated control-board wear.
  • Install Difficulty: 2/5 — Power down and lock out the furnace at the disconnect before starting. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to confirm 24V output after install). Photograph all low-voltage wiring before disconnecting. Note: OEM part number HT01BC116 has been superseded; current shipping part is HT680054, a direct factory replacement.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for Carrier model PG9MAA060100ACKA gas furnace. Also replaces cross-reference part numbers HT01BC116, HT01BC115, HT01BB126, HT01CT120, HT01BC120, and HT01AW115. Verify your existing transformer's primary voltage (120V) and VA rating (40VA) on the data plate before ordering. Need help confirming fitment? Our parts team is standing by.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAA060100ACKA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAA060100ACKA. 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 PG9MAA060100ACKA?
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?
