OEM Carrier Transformer 40VA 120V to 24V for Model KCABA02013TG

This is the factory OEM replacement transformer (part number HT01BC116) for the Carrier KCABA02013TG air handler. The transformer steps down line voltage (120V) to the 24V control circuit voltage required to power your thermostat, control board, and all low-voltage components. When this transformer fails, the entire control circuit goes dead — your thermostat will show a blank screen, the system will not respond to any calls for heating or cooling, and no contactors or relays will energize. It is often one of the first components to check when a system appears completely unresponsive.

  • Specs: 40VA rated | 120V primary / 24V secondary | OEM part number HT01BC116 | Factory-matched output for Carrier KCABA02013TG control circuit requirements
  • OEM vs Generic: This OEM transformer is wound to Carrier's exact VA rating and output tolerance. Undersized or off-tolerance generic transformers can overheat, trip their internal breaker repeatedly, or deliver insufficient voltage to operate contactors and gas valves reliably.
  • Install difficulty: 2/5 — Turn off all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to confirm 24V output after installation. Label and photograph all wire connections before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier KCABA02013TG air handler. Confirm your existing transformer's VA rating and primary/secondary voltages on the unit data plate before ordering. Our fitment team is available to verify compatibility prior to purchase — order with confidence and get your system back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier KCABA02013TG?
Yes. This is the factory-specified OEM transformer for the Carrier KCABA02013TG. 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 KCABA02013TG?
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?
