OEM Carrier Transformer 40VA 120V/24V for Model GB3AAV060135AFJA — Part HT01BC116

This is the factory OEM replacement transformer for the Carrier GB3AAV060135AFJA gas furnace. The transformer steps down line voltage from 120V AC to the 24V AC signal used by your thermostat, control board, gas valve, and other low-voltage components. When this part fails, the entire control circuit goes dead — your thermostat will appear blank or unresponsive, and the furnace will not attempt ignition at all. A failed transformer is often overlooked during troubleshooting but is one of the most common causes of a completely non-responsive furnace.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Factory-matched for Carrier GB3AAV060135AFJA
  • OEM vs Generic: This OEM unit is wound to exact factory VA and voltage tolerances, ensuring reliable 24V signal delivery. Undersized or off-tolerance aftermarket transformers can cause erratic board behavior, nuisance lockouts, and premature contactor failure.
  • Install difficulty: 2/5 — Shut off power to the furnace at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Label all low-voltage wires before disconnecting. Verify 24V output with a multimeter after installation before restoring full power.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier GB3AAV060135AFJA gas furnace. Confirm your existing transformer's VA rating and primary/secondary voltages on the data plate or component label before ordering. If you have questions about fitment, our HVAC parts specialists verify compatibility before you buy — no guesswork.

Frequently Asked Questions

Does this Transformer fit my Carrier GB3AAV060135AFJA — HT01BC116?
Yes. This is the factory-specified OEM transformer for the Carrier GB3AAV060135AFJA — HT01BC116. 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 GB3AAV060135AFJA — HT01BC116?
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?
