OEM Carrier Furnace Transformer 40VA 120V/24V for Model PG8MAA060155ACJA (HT01BC116 / HT680054)

This OEM step-down transformer is the factory-specified replacement for the Carrier PG8MAA060155ACJA gas furnace. Originally sold under part number HT01BC116, this component has been updated by Carrier to the current OEM part number HT680054 — a direct drop-in factory replacement supplied in a Carrier-authorized parts box. The transformer converts 120V line voltage down to 24V AC to power all low-voltage control components including the thermostat, gas valve, and control board. When it fails, the result is a completely unresponsive system: the thermostat goes dark, the furnace will not ignite, and no low-voltage signals reach any component downstream.

  • Specs: 40VA rating | 120V primary / 24V secondary | 50/60 Hz | Single-phase | Foot-mount | Compact 3" × 2-2/16" × 2" form factor | Wire lead connections
  • OEM vs Generic: This is a genuine Carrier OEM unit shipped in a factory-authorized box, matched precisely to the PG8MAA060155ACJA's low-voltage circuit load. Generic transformers may be rated at ±10% VA tolerance, risking undervoltage to the gas valve or control board and causing nuisance lockouts.
  • Install difficulty: 2/5 — Shut off power at the breaker and confirm 0V with a multimeter before touching wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before removal. The foot-mount bracket bolts directly into the existing standoffs — no modification required.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8MAA060155ACJA gas furnace. This OEM part (HT01BC116, superseded by HT680054) also replaces cross-reference numbers HT01BC115, HT01BB126, HT01CT120, HT01BC120, HT01AW115, and several others — confirming broad fitment across Carrier, Bryant, and Payne furnace platforms with identical low-voltage circuit requirements. Verify your unit's data plate shows 120V primary control transformer before ordering. Need fitment confirmed? Our team checks compatibility before you buy — order with confidence and get it shipped today.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8MAA060155ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8MAA060155ACJA. 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 PG8MAA060155ACJA?
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?
