OEM Carrier Igniter LH33ZS003 for Model GB3AAV036070AEJA

Restore dependable startup with this genuine OEM Carrier hot surface igniter (LH33ZS003). The igniter glows to light the burners on each heating call; over time the silicon-carbide or silicon-nitride element develops hairline cracks or simply burns out, leaving you with a furnace that clicks and tries to start but never lights. This OEM igniter is matched to the exact resistance, mounting bracket, and connector required by the Carrier GB3AAV036070AEJA gas furnace, ensuring a fast, reliable glow and proper ignition timing. Installation is straightforward for handy homeowners — about 20 minutes: cut power, remove the burner-area access, unscrew the igniter bracket, unplug the connector, and install the replacement. Handle the fragile element only by its base to avoid cracking it. A fresh OEM igniter eliminates no-heat calls and protects against repeated failed-ignition lockouts. In stock and ships same-day when ordered before 3PM CST, so you can beat the cold without waiting days for parts.

Frequently Asked Questions

Does this Igniter fit my Carrier Model GB3AAV036070AEJA?
Yes. This is the factory-specified OEM igniter for the Carrier Model GB3AAV036070AEJA. 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 GB3AAV036070AEJA?
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.
