OEM Carrier Control Transformer 40VA 120V/24V for Model N6A48NG481824

This OEM replacement transformer (part number HT01BC116) is the factory-specified control circuit transformer for the Carrier N6A48NG481824 packaged gas/electric unit. The transformer steps down line voltage from 120V to 24V AC to power the entire low-voltage control circuit — including the thermostat, contactor coil, gas valve, and control board. When the transformer fails, nothing in the system responds: the thermostat goes blank, the unit won't start, and you may find a blown 3A fuse on the control board. A failed transformer is often the first suspect when a system goes completely silent.

  • Specs: Primary voltage: 120V AC | Secondary voltage: 24V AC | VA rating: 40VA | OEM part number: HT01BC116 | Factory-matched output for stable low-voltage control
  • OEM vs Generic: This OEM transformer is wound to Carrier's exact VA and voltage tolerance specifications. Generic transformers can output slightly off-spec voltage, causing nuisance tripping, contactor chatter, or premature control board failure — especially under peak load conditions.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify voltage is absent before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter. Label or photograph all wiring connections before removal. Reconnect primary (line) leads first, then secondary (24V) leads.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Designed and tested for the Carrier N6A48NG481824 packaged unit. Always verify your existing transformer's primary voltage, secondary voltage, and VA rating against your unit's data plate before ordering. If you're unsure of fitment, our HVAC parts specialists can confirm compatibility before you buy — no guesswork required. Order today and get your system back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier N6A48NG481824?
Yes. This is the factory-specified OEM transformer for the Carrier N6A48NG481824. 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 N6A48NG481824?
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?
