OEM Carrier Transformer 40VA 120V/24V for Model GB3AAV060115AGJA

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier GB3AAV060115AGJA gas furnace. The transformer steps down 120V line voltage to the 24V control voltage required to power the thermostat circuit, control board, gas valve, and all low-voltage accessories. When this transformer fails, the entire control circuit goes dead — the thermostat displays nothing, the furnace won't respond to any call for heat or cooling, and no diagnostic fault codes will appear because the board itself has no power to operate.

  • Specs: 40VA rating | 120V primary / 24V secondary | Factory OEM part number HT01BC116 | Designed to factory tolerance for the Carrier GB3AAV060115AGJA control circuit
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by the furnace control board. Undersized or off-spec generic units can cause nuisance tripping, board damage, or premature failure of downstream low-voltage components.
  • Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify 24V output after install. Photograph all wiring connections before removing the old transformer.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier GB3AAV060115AGJA gas furnace. Verify your existing transformer's VA rating and primary/secondary voltages on the data plate before ordering. Our parts specialists are available to confirm fitment — order with confidence and get your furnace back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier GB3AAV060115AGJA?
Yes. This is the factory-specified OEM transformer for the Carrier GB3AAV060115AGJA. 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 GB3AAV060115AGJA?
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?
