OEM Carrier Hot Surface Igniter LH33ZS003 for Model N6A48NG481818

Get your furnace lighting again with the OEM Carrier LH33ZS003 hot surface igniter, the silicon-nitride heating element that glows to ignite the gas burners on every call for heat. Manufactured to exact factory specifications, this genuine Carrier igniter is fully compatible with model N6A48NG481818 and provides the precise resistance and durability the control board requires. A cracked or worn-out igniter is the leading cause of no-heat and ignition-lockout failures, and this rugged OEM element resists thermal fatigue far better than generic replacements. Installation is easy and usually takes less than 30 minutes: turn off power and gas, remove the burner-compartment door, unplug the old igniter, unscrew the mounting bracket, and install the new unit—handling the element only by its ceramic base to prevent contamination. This is a brand-new genuine part, not refurbished or aftermarket, ensuring dependable ignition season after season. Order before 3 PM CST and your igniter ships same-day from our warehouse, so you can restore heat quickly and affordably without scheduling an expensive service appointment.

Frequently Asked Questions

Does this Igniter fit my Carrier Model N6A48NG481818?
Yes. This is the factory-specified OEM igniter for the Carrier Model N6A48NG481818. 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 N6A48NG481818?
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.
