OEM Carrier Control Transformer 40VA 120V/24V for Model N6A48NG480198

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier N6A48NG480198 packaged unit. The transformer steps down line voltage from 120V to 24V to power the control board, thermostat, and all low-voltage safety circuits throughout the system. When it fails, the result is total loss of control — a blank thermostat, an unresponsive system, or a tripped fuse on the secondary circuit. If your Carrier unit powers on but does nothing, a failed transformer is often the first component to test.

  • Specs: 40VA rating | Primary: 120V | Secondary: 24V | OEM Part Number: HT01BC116 | Direct factory-matched replacement
  • OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by the Carrier control board. Undersized or off-tolerance generic units can cause nuisance fuse trips, erratic thermostat behavior, or premature control board failure.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label all low-voltage wiring before disconnecting. Confirm 24V output with a multimeter after installation before restoring full system power.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed for the Carrier N6A48NG480198 packaged unit. Verify OEM part number HT01BC116 against your unit's data plate or existing transformer label before ordering. Our HVAC parts specialists are available to confirm fitment — don't guess on a control circuit component. In stock and ready to ship today.

Frequently Asked Questions

Does this Transformer fit my Carrier N6A48NG480198?
Yes. This is the factory-specified OEM transformer for the Carrier N6A48NG480198. 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 N6A48NG480198?
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?
