OEM Carrier Transformer 40VA 120V/24V for Model GA2AAD060090ABJA

This is the factory OEM replacement transformer (part number HT01BC116) for the Carrier GA2AAD060090ABJA gas furnace. The control circuit transformer steps down line voltage from 120V to 24V to power the thermostat, control board, gas valve, and all low-voltage control components. When this transformer fails, the entire control circuit goes dark — the thermostat loses power, nothing responds, and the system will not heat or cool regardless of thermostat input.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Factory-matched for Carrier GA2AAD060090ABJA
  • OEM vs Generic: OEM transformers are wound and insulated to Carrier's exact VA and thermal spec. Undersized or off-tolerance generic transformers can overheat, trip their internal breaker repeatedly, or fail prematurely under full control circuit load.
  • 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 confirm 24V output after install). Label all low-voltage wires before removal to ensure correct reconnection.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model GA2AAD060090ABJA gas furnace. Confirm your existing transformer's VA rating and primary/secondary voltages on the data plate or transformer label before ordering. Our parts specialists are available to verify fitment — order with confidence and get your system back online today.

Frequently Asked Questions

Does this Transformer fit my Carrier GA2AAD060090ABJA?
Yes. This is the factory-specified OEM transformer for the Carrier GA2AAD060090ABJA. 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 GA2AAD060090ABJA?
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?
