OEM Carrier Transformer 40VA 120V to 24V for Model KCABAKCBBA02013TG

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier KCABAKCBBA02013TG. The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, control board, contactor coil, and all low-voltage safety circuits. When this transformer fails — whether from a shorted wire, a blown internal fuse, or age-related winding degradation — the entire control circuit goes dark. Nothing responds: no thermostat communication, no ignition sequence, no compressor engagement.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part HT01BC116 | Factory-matched output tolerance for stable control circuit operation
  • OEM vs Generic: OEM transformers from Carrier are wound and insulated to exact VA and voltage specifications. Undersized or off-tolerance generic units can overheat under load, trip internal thermal protectors prematurely, or deliver unstable 24V output that causes erratic board behavior and nuisance lockouts.
  • Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Confirm 0V at primary terminals before touching wiring. Note wire colors and terminal positions before removal. Restore power only after all connections are secure and covers replaced.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed and factory-matched for Carrier model KCABAKCBBA02013TG. Cross-reference OEM part number HT01BC116 against your unit's data plate to confirm voltage and VA rating before ordering. Our fitment team is available to verify compatibility — just reach out before you order. In stock and ships today.

Frequently Asked Questions

Does this Transformer fit my Carrier KCABAKCBBA02013TG?
Yes. This is the factory-specified OEM transformer for the Carrier KCABAKCBBA02013TG. 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 KCABAKCBBA02013TG?
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?
