OEM Carrier Igniter LH33ZS003 for Model N6A48NG481455

This genuine OEM Carrier hot surface igniter lights the burners on your N6A48NG481455 gas furnace, glowing red-hot on each heat call to ignite the gas safely and reliably. A cracked, pitted, or burned-out igniter is the most frequent cause of no-heat breakdowns, usually appearing as a furnace that attempts to start but never fires. Manufactured to factory specifications, this igniter matches the original resistance, mounting bracket, and connector for an exact fit on the N6A48NG481455, restoring consistent ignition every cycle. Replacement is an easy DIY repair: turn off power, remove the single screw, unplug the old igniter, and install the new one—handling it only by the ceramic base to protect the delicate element. Most installs take 15 minutes. Genuine OEM igniters last far longer than universal substitutes and preserve your warranty. We keep this part in stock for immediate dispatch. Order before 3PM CST for same-day shipping and get your heat back fast. Fully compatible with the N6A48NG481455 furnace.

Frequently Asked Questions

Does this Igniter fit my Carrier Model N6A48NG481455?
Yes. This is the factory-specified OEM igniter for the Carrier Model N6A48NG481455. 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 Model N6A48NG481455?
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.
