OEM Carrier Control Transformer 40VA 120V/24V for Model N6A48NG482017

This is the factory OEM replacement transformer (part number HT01BC116) for the Carrier N6A48NG482017 packaged unit. The control transformer steps down line voltage from 120V to 24V to power the entire low-voltage control circuit — including your thermostat, contactor coil, gas valve, and control board. When this transformer fails, nothing in the system responds: the thermostat goes blank, the unit won't call for heating or cooling, and you may find a blown 3-amp fuse on the control board as a secondary symptom.

Specs: Input 120V AC | Output 24V AC | 40VA rating | OEM part number HT01BC116 | Factory-matched impedance and thermal protection
OEM vs Generic: This OEM transformer is wound to Carrier's exact VA rating and insulation class. Undersized or off-spec generic transformers frequently overheat, trip their thermal cutout, or fail prematurely — especially when multiple 24V accessories share the circuit.
Install difficulty: 2/5 — Shut off power at the disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Label or photograph all low-voltage wiring connections before removing the old transformer.
Warranty: 1-year OEM factory warranty included. Orders placed by 3 PM local time ship the same business day from our HVAC-dedicated warehouse.

Compatibility: Designed specifically for the Carrier N6A48NG482017 packaged unit. Verify your existing transformer's input/output voltage and VA rating on the unit data plate or transformer label before ordering. If you are unsure of fitment, our parts specialists confirm compatibility before your order ships — no guesswork required.

Frequently Asked Questions

Does this Transformer fit my Carrier N6A48NG482017?

Yes. This is the factory-specified OEM transformer for the Carrier N6A48NG482017. 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 N6A48NG482017?

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.
