OEM Carrier Transformer 40VA 120V to 24V for Model N6A48NG481882

This OEM step-down transformer (part# HT01BC116) is the factory-specified replacement for the Carrier N6A48NG481882 packaged unit. The transformer converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, contactor coil, and gas valve. When the transformer fails, the result is total control loss: a blank thermostat, no response from any system component, and a completely non-functional unit until it is replaced.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Factory-matched output for safe, stable low-voltage control power
  • OEM vs Generic: This OEM transformer is wound to Carrier's exact VA rating and insulation class, ensuring full ampacity headroom for all connected control devices. Undersized or off-brand transformers can overheat, blow fuses repeatedly, or fail to energize the contactor coil reliably.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Note wire color and terminal positions before removing the old unit.
  • Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier N6A48NG481882 packaged gas/electric unit. Confirm your existing transformer's VA rating and primary/secondary voltages on the data plate before ordering. Our fitment team is available to verify compatibility — just reach out before you buy. Order today and most in-stock parts ship the same business day.

Frequently Asked Questions

Does this Transformer fit my Carrier N6A48NG481882?
Yes. This is the factory-specified OEM transformer for the Carrier N6A48NG481882. 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 N6A48NG481882?
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?
