OEM Carrier Hot Surface Igniter LH33WZ010 for Model LC3:50LC400468

This is the OEM factory-specified hot surface igniter (part number LH33WZ010) for the Carrier LC3:50LC400468 packaged gas heating unit. The hot surface igniter is a critical component in the furnace ignition sequence — it heats to over 2,000°F within seconds to ignite the gas burners. When this igniter fails, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat. Common symptoms include a furnace that starts the inducer motor and opens the gas valve but never produces a flame, followed by a fault lockout code.

  • Specs: Silicon carbide / silicon nitride hot surface igniter | OEM part number LH33WZ010 | Factory-matched electrical resistance and mounting geometry for direct drop-in installation | Rated for continuous cycling duty
  • OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory specifications. Generic igniters frequently differ in resistance rating, mounting bracket angle, or lead wire length — causing premature cracking, misalignment with the burner port, or nuisance lockouts. OEM ensures first-time reliability.
  • Install Difficulty: 2/5 — Turn off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and early failure. Use gloves or handle by the lead wire assembly only.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier LC3:50LC400468 packaged gas/electric unit. Always verify the OEM part number on your existing igniter or equipment data plate before ordering. Our fitment team is available to confirm compatibility — contact us before you order if you have any questions. In stock and ready to ship today.

Frequently Asked Questions

Does this Igniter fit my Carrier LC3:50LC400468?
Yes. This is the factory-specified OEM igniter for the Carrier LC3:50LC400468. 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 LC3:50LC400468?
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.
