OEM Carrier Control Transformer 40VA 120V/24V for Model N6A48NG480202

This is the factory OEM replacement control transformer (part# HT01BC116) for the Carrier N6A48NG480202 packaged unit. The transformer steps down line voltage from 120V to the 24V signal required by your thermostat, control board, contactor coil, and every other low-voltage component in the system. When it fails, absolutely nothing works — the thermostat goes dark, the system refuses to respond to any call for heating or cooling, and you may blow a low-voltage fuse repeatedly. This is often the first part to check when you have zero control circuit response.

  • Specs: 40VA rated | Primary: 120V AC | Secondary: 24V AC | OEM part number HT01BC116 | Direct plug-in/mount replacement with factory-matched terminals
  • OEM vs Generic: This OEM transformer is wound to Carrier's exact VA and voltage tolerance specs. Undersized or off-spec generic transformers can overheat under load, trip thermal protectors, and damage downstream control boards — a far costlier repair.
  • Install difficulty: 2/5 — Disconnect power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to confirm 24V output after install. Label or photograph all wiring connections before removing the old unit.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier N6A48NG480202 packaged gas/electric unit. Verify your existing transformer's VA rating and primary/secondary voltages against your unit's data plate before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — no guesswork.

Frequently Asked Questions

Does this Transformer fit my Carrier N6A48NG480202?
Yes. This is the factory-specified OEM transformer for the Carrier N6A48NG480202. 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 N6A48NG480202?
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?
