OEM Carrier Transformer 40VA 120V/24V for Model N6D48NG482026

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier N6D48NG482026 packaged unit. It steps down line voltage from 120V to 24V to power the low-voltage control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the entire control circuit goes dead: the thermostat shows no response, the system won't call for heating or cooling, and nothing operates despite power being present at the unit.

  • Specs: Input: 120V AC | Output: 24V AC | 40VA rating | OEM part number HT01BC116 | Factory-matched for Carrier N6D48NG482026
  • OEM vs Generic: This OEM transformer meets exact Carrier factory specifications for VA rating and insulation class. Generic substitutes may be under-rated in VA, causing premature thermal cutout trips and repeated control circuit failures under normal load.
  • Install difficulty: 2/5 — Shut off all power to the unit at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify output voltage after installation. Label or photograph all low-voltage wiring connections before removing the old transformer.
  • Warranty: 1-year OEM factory warranty. Orders received by 3 PM ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier N6D48NG482026 packaged unit. Verify input voltage (120V) and VA rating on your unit's data plate before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you buy — no guesswork required.

Frequently Asked Questions

Does this Transformer fit my Carrier N6D48NG482026?
Yes. This is the factory-specified OEM transformer for the Carrier N6D48NG482026. 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 N6D48NG482026?
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?
