OEM Carrier Transformer 40VA 120V to 24V for Model GB3AAV060135ADJA

This is the factory OEM replacement transformer (part number HT01BC116) for the Carrier GB3AAV060135ADJA gas furnace. The transformer steps down 120V line voltage to 24V to power the control board, thermostat circuit, and low-voltage control components throughout the system. When this part fails, the entire control circuit loses power — symptoms include a completely unresponsive thermostat, a blank control board, and a furnace that won't start, heat, or respond to any input despite having line voltage present.

  • Specs: 40VA rating | 120V primary / 24V secondary | OEM part number HT01BC116 | Factory-matched to Carrier GB3AAV060135ADJA wiring harness and control board
  • OEM vs Generic: OEM transformers are wound and rated to exact factory VA specifications. Undersized generic units can overheat under full control circuit load, blowing the internal thermal fuse and failing prematurely — often within a single heating season.
  • Install difficulty: 2/5 — Shut off all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Check for shorted low-voltage wiring before installing the new transformer, as a wiring short is the most common cause of transformer failure and will damage the replacement unit immediately.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed and factory-specified for the Carrier GB3AAV060135ADJA gas furnace. Cross-reference OEM part number HT01BC116 against your unit's data plate and existing transformer label before ordering. If you need fitment confirmation, our HVAC parts team is available to verify compatibility before you purchase — same-day shipping guaranteed on in-stock parts.

Frequently Asked Questions

Does this Transformer fit my Carrier GB3AAV060135ADJA?
Yes. This is the factory-specified OEM transformer for the Carrier GB3AAV060135ADJA. 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 GB3AAV060135ADJA?
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?
