OEM Carrier Furnace Control Transformer 40VA 120V–24V for Model PG8MAA060155AAJA

This is the factory-specified OEM step-down control transformer for the Carrier PG8MAA060155AAJA gas furnace, replacing original part number HT01BC116 (current OEM equivalent: HT680054). The transformer converts 120V line voltage to 24V AC, powering every low-voltage component in the system — including the control board, thermostat circuit, gas valve coil, and inducer relay. When it fails, the result is typically a completely unresponsive furnace: the thermostat calls for heat but nothing happens, the control board shows no activity, or the system trips a low-voltage fuse repeatedly.

  • Specs: 40VA capacity | 120V primary / 24V secondary | 60 Hz single-phase | Wire-lead connection with foot-mount bracket | Compact form factor: 3″ L × 2⅛″ W × 2″ H
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances, protecting sensitive control boards and gas valve coils from under- or over-voltage. Generic units often run off-spec, increasing the risk of nuisance fuse trips and premature board failures.
  • Install difficulty: 2/5 — Shut off power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output post-install). Photograph all wire connections before disconnecting the old transformer. Note: HT01BC116 has been superseded — this ships as the current OEM part HT680054, a direct drop-in replacement.
  • Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day when placed by 5 PM EST.

Compatibility: Designed for the Carrier PG8MAA060155AAJA gas furnace. Also replaces HT01BC115, HT01BB126, HT01CT120, HT01BC120, HT01AW115, HT01AA012, HT01AQ110, HT01CT210, 322666-701, 322953-302, and B1810113. Confirm primary voltage (120V) on your unit's data plate before ordering. Need help verifying fitment? Our HVAC parts specialists are standing by.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8MAA060155AAJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8MAA060155AAJA. 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 PG8MAA060155AAJA?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
