OEM Carrier Hot Surface Igniter LH33ZS003 for Model FPAA100D34CN

This OEM Carrier hot surface igniter (LH33ZS003) glows red-hot to light the gas burners on your FPAA100D34CN furnace. When the igniter cracks, weakens, or fails, the furnace will not produce heat and may lock out after several ignition attempts—a no-heat call that's almost always traced to a failed igniter. Manufactured to genuine Carrier specifications, this igniter matches the original resistance and mounting of the FPAA100D34CN for a guaranteed fit and proper light-off. Installation is a straightforward DIY job: remove the burner-compartment screw, unplug the igniter connector, and seat the new igniter without touching the fragile silicon-carbide element. Most repairs take about 20 minutes. A fresh OEM igniter restores fast, reliable starts and prevents repeated lockouts through the heating season. Handle by the ceramic base only for maximum lifespan. Order before 3PM CST and it ships same-day, so you can get warm again fast. In stock and ready to ship today.

Frequently Asked Questions

Does this Igniter fit my Carrier Model FPAA100D34CN?
Yes. This is the factory-specified OEM igniter for the Carrier Model FPAA100D34CN. 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 FPAA100D34CN?
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.
