OEM Carrier Control Transformer 40VA 120V/24V for Model N6D48NG480094

This is the OEM factory-specified control transformer (part number HT01BC116) for the Carrier N6D48NG480094 packaged or split system. The transformer steps down line voltage from 120V to 24V AC 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 display may go blank, the system will not respond to any calls for heating or cooling, and no safety controls will operate. It is often the first component to suspect when nothing works and all fuses check out.

  • Specs: Primary voltage: 120V AC | Secondary voltage: 24V AC | VA rating: 40VA | OEM part number: HT01BC116 | Factory-matched output for stable control circuit operation
  • OEM vs Generic: OEM transformers are wound to exact factory VA and voltage tolerances, ensuring reliable 24V output under full control circuit load. Generic units may sag under load, causing intermittent lockouts, nuisance tripping, or premature contactor coil failure.
  • Install difficulty: 2/5 — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Confirm primary and secondary wire connections match original wiring. Photograph all wiring before removal.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier N6D48NG480094. Verify your existing transformer's primary voltage (120V), secondary voltage (24V), and VA rating (40VA) on the unit's data plate before ordering. If you are unsure of fitment, our HVAC parts specialists can verify compatibility before you purchase.

Frequently Asked Questions

Does this Transformer fit my Carrier N6D48NG480094?
Yes. This is the factory-specified OEM transformer for the Carrier N6D48NG480094. 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 N6D48NG480094?
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?
