OEM Carrier Furnace Transformer 120V–24V 40VA for Model PG8UAA060111AAJA (HT01BC116 / HT680054)

This OEM step-down transformer is the factory-specified replacement for the Carrier PG8UAA060111AAJA gas furnace. It converts 120V line voltage to the 24V AC signal that powers every low-voltage component in your system — the thermostat, gas valve, control board relays, and zone controls. When the transformer fails, the entire control circuit goes dead: the furnace won't respond to the thermostat, the board shows no life, and you may measure 0V between the R and C terminals on your control board. This is the correct OEM replacement to restore full operation.

  • Specs: Input 120V AC | Output 24V AC | 40VA rating | Foot-mount configuration | Wire lead connections | 60 Hz | Replaces OEM part HT01BC116 (superseded by HT680054)
  • OEM vs Generic: OEM Carrier transformers are wound to exact factory VA and voltage tolerances, protecting sensitive control boards from under- or over-voltage. Generic units often run outside rated tolerances, risking repeat transformer failure or board damage.
  • Install Difficulty: 2/5 — Turn off power at the breaker and confirm 0V before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or quick-connect terminals. Photograph all wiring connections before disconnecting. Verify 24V output at R–C terminals after installation.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8UAA060111AAJA packaged gas furnace. OEM part number HT01BC116 has been superseded by HT680054 — both are covered by this listing. Cross-references include HT01BC115, HT01BB126, HT01BC120, and HT01AW115. Confirm your unit's data plate shows a 120V primary and 24V secondary before ordering. Have a fitment question? Our HVAC parts team verifies compatibility before you buy — order with confidence and get your furnace back online today.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8UAA060111AAJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8UAA060111AAJA. 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 PG8UAA060111AAJA?
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?
