OEM Carrier Igniter LH33ZS003 for Model GB3AAV036070ADJA

Get reliable ignition back with this genuine OEM Carrier hot surface igniter (LH33ZS003). The igniter heats up to light the burners every time the thermostat calls for heat, and its brittle element naturally degrades and cracks with thermal cycling — the usual reason a furnace attempts to start, clicks, but never produces a flame. This OEM igniter is built to the precise resistance value, bracket geometry, and plug type required by the Carrier GB3AAV036070ADJA gas furnace for a quick, consistent glow and correct ignition timing. The job suits a confident DIYer and takes roughly 20 minutes: disconnect power, open the burner access panel, unscrew the igniter mount, release the connector, and fit the new part. Always grip the element by its ceramic base — touching the fragile tip can cause premature failure. Installing a fresh OEM igniter ends no-heat lockouts and restores dependable operation. In stock and ships same-day when ordered before 3PM CST, so you won't be left in the cold.

Frequently Asked Questions

Does this Igniter fit my Carrier Model GB3AAV036070ADJA?
Yes. This is the factory-specified OEM igniter for the Carrier Model GB3AAV036070ADJA. 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 GB3AAV036070ADJA?
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.
