OEM Carrier Hot Surface Igniter LH33ZS003 for GB1AAV036045AFJA

The OEM Carrier hot surface igniter (LH33ZS003) glows to ignite the gas burners at the start of each heating cycle. Made from rugged silicon nitride, it resists the thermal cracking that retires older silicon carbide igniters early. If your blower runs but no heat is produced, or you hear clicking with no ignition, a failed igniter is the usual culprit. This igniter is a direct-fit replacement for the Carrier GB1AAV036045AFJA furnace, matching the OEM bracket, lead length, and connector for true plug-and-play installation. The swap is straightforward for handy homeowners—turn off power and gas, remove the mounting screw, unplug the connector, and seat the new igniter without touching the fragile element. Choosing the genuine OEM part ensures correct resistance and reliable ignition, avoiding the premature failures common with low-cost aftermarket units. In stock now and ships same-day on orders placed before 3PM CST. Restore your heat quickly with the igniter Carrier designed specifically for your furnace model.

Frequently Asked Questions

Does this Igniter fit my Carrier GB1AAV036045AFJA?
Yes. This is the factory-specified OEM igniter for the Carrier GB1AAV036045AFJA. 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 GB1AAV036045AFJA?
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.
