OEM Carrier Igniter LH33ZS003 for Model N6A48NG481456

This genuine OEM Carrier hot surface igniter is the ignition source for your N6A48NG481456 gas furnace, heating up to glowing temperature to light the burners on each call for heat. A cracked or burned-out igniter is the number-one cause of no-heat failures, often showing as a furnace that clicks and tries to start but never fires. Built to factory specifications, this igniter matches the original resistance, mounting bracket, and plug connector for an exact fit on the N6A48NG481456, restoring dependable startup every cycle. Replacement is an easy DIY job: cut power at the switch, remove the single mounting screw, unplug the old igniter, and install the new one—handling it only by the base to avoid damaging the fragile element. Most homeowners finish in 15 minutes. Genuine OEM construction outlasts cheap universal igniters and protects your warranty. We keep this igniter in stock. Order before 3PM CST for same-day shipping so your heat is restored fast. Fully compatible with the N6A48NG481456 furnace.

Frequently Asked Questions

Does this Igniter fit my Carrier Model N6A48NG481456?
Yes. This is the factory-specified OEM igniter for the Carrier Model N6A48NG481456. 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 N6A48NG481456?
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.
