OEM Carrier Igniter LH33ZS003 for Model GB3AAV036075AAJA

The OEM Carrier hot surface igniter (LH33ZS003) lights the gas burners every time your Carrier GB3AAV036075AAJA furnace calls for heat. When powered, its silicon nitride element glows hot to ignite the burner manifold. A cracked, eroded, or burned-out igniter is the most common reason for a furnace that cycles and clicks but never fires—if you have no heat, check the igniter first. This direct-replacement part matches the factory specification for the GB3AAV036075AAJA, including the proper mounting bracket and plug connector for a true plug-and-play fit. Installation is moderate and takes about 20 minutes: disconnect power, remove the mounting screws, unplug the harness, and reverse with the new igniter. Handle the fragile element only by its ceramic base and never touch the hot surface, which can fail from skin oils. Restore quick, reliable ignition with a genuine Carrier igniter built to OEM standards. In stock and ships same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Igniter fit my Carrier Model GB3AAV036075AAJA?
Yes. This is the factory-specified OEM igniter for the Carrier Model GB3AAV036075AAJA. 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 GB3AAV036075AAJA?
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.
