OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6A48NG481454

This is the OEM factory-specified hot surface igniter (part number LH33WZ010) for the Carrier N6A48NG481454 packaged gas unit. The igniter functions as the spark electrode that generates the heat necessary to light the burner assembly during each call for heat. When this component fails, the control board will attempt ignition, find no flame established, and lock out the system — leaving you with a furnace that attempts to start but produces no heat, often logging a fault code indicating ignition failure.

  • Specs: OEM spark electrode igniter | Part No. LH33WZ010 | Factory-matched geometry and tip spacing | Rated for Carrier N6A48NG481454 packaged gas configuration | Direct plug-in connector for tool-free wiring reconnection
  • OEM vs Generic: OEM igniters from Carrier are manufactured to exact electrode gap tolerances and ceramic insulator ratings. Aftermarket units frequently ship with inconsistent tip spacing, leading to weak spark, nuisance lockouts, and premature ceramic cracking under thermal cycling stress.
  • Install Difficulty: 2/5 — Shut off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Do not touch the ceramic or electrode tip with bare hands — skin oils cause hot spots that crack the insulator. Photograph existing wiring before disconnecting the harness connector.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3 PM EST ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier N6A48NG481454 packaged gas/electric unit. Verify your existing igniter part number against LH33WZ010 and inspect the burner assembly configuration before ordering. If you are unsure of fitment, our HVAC parts specialists are available to confirm compatibility before your order is placed — no guesswork required.

Frequently Asked Questions

Does this Igniter fit my Carrier N6A48NG481454?
Yes. This is the factory-specified OEM igniter for the Carrier N6A48NG481454. 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 igniter on my Carrier N6A48NG481454?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter 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 igniter?
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?
