OEM Carrier Transformer 40VA 120V to 24V Control Circuit for Model GA2AAD060110ACJA

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier GA2AAD060110ACJA packaged gas/electric unit. The transformer steps down 120V line voltage to the 24V signal voltage required to power the thermostat circuit, control board, contactor coil, and gas valve. When this component fails, the entire control circuit goes dead — the thermostat display may go blank, the system will not respond to any calls for heating or cooling, and no 24V accessories will function. It is often the first component to test when nothing in the system responds.

  • Specs: 40VA rating | 120V primary / 24V secondary | Factory-matched OEM output | Compatible with R-410A system control architecture | OEM Part Number: HT01BC116
  • OEM vs Generic: The OEM HT01BC116 transformer is wound to exact VA and voltage tolerance specifications. Generic transformers may run under-rated VA, causing thermal overload shutdowns under full 24V load — especially problematic when multiple accessories share the control circuit.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire nuts or push connectors, multimeter. Photograph all wiring connections before removal. Verify 24V output with a multimeter after installation before restoring full power.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our stocked warehouse.

Compatibility: Engineered for the Carrier GA2AAD060110ACJA packaged unit. Always confirm your existing transformer's VA rating and primary/secondary voltages on the unit data plate or existing component label before ordering. Our fitment team is available to verify compatibility before you buy. Order today and receive same-day shipping on in-stock OEM parts.

Frequently Asked Questions

Does this Transformer fit my Carrier GA2AAD060110ACJA?
Yes. This is the factory-specified OEM transformer for the Carrier GA2AAD060110ACJA. 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 GA2AAD060110ACJA?
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.
