OEM Carrier 40VA Control Transformer for Model GB1AAV060155ACJA

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier GB1AAV060155ACJA gas furnace. The transformer steps down 120V line voltage to 24V AC, powering the thermostat, control board, gas valve, and all low-voltage control circuits in your system. When this transformer fails, the entire control circuit loses power — the thermostat goes blank, the furnace won't respond to any calls for heat or cooling, and nothing works. A blown transformer is often traced to a shorted control wire, failed contactor coil, or a wiring fault that caused an overcurrent event.

  • Specs: 40VA rated | 120V primary input | 24V AC secondary output | Factory OEM part number HT01BC116 | Engineered to exact Carrier tolerance for reliable, long-term control circuit operation
  • OEM vs Generic: OEM transformers are wound to precise VA ratings matching the total low-voltage load of your specific furnace. Undersized or off-tolerance generic units can overheat, trip internal thermal fuses prematurely, or fail to sustain voltage under full load — leading to intermittent lockouts and callbacks.
  • Install difficulty: 2/5 — Disconnect power at the breaker and confirm voltage is off with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter. Before replacing, inspect all 24V control wiring for shorts to ground — a shorted wire will destroy the new transformer. Photograph wiring connections before removal.
  • Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier GB1AAV060155ACJA gas furnace. Verify your existing transformer's VA rating and primary/secondary voltages on the data plate before ordering. If you're unsure of fitment, our HVAC parts specialists will confirm compatibility before you purchase — same-day shipping available on all in-stock orders.

Frequently Asked Questions

Does this Transformer fit my Carrier GB1AAV060155ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier GB1AAV060155ACJA. 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 GB1AAV060155ACJA?
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?
