OEM Carrier Hot Surface Igniter LH33WZ010 for Model LC3:50LC400677

This is the OEM factory-specified hot surface igniter (part number LH33WZ010) designed as a direct replacement for the Carrier LC3:50LC400677 furnace or heating system. The hot surface igniter is a critical component in the ignition sequence — it heats to extreme temperatures (typically 1,800°F+) to ignite the gas burner on each heating call. When the igniter fails, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat. Common symptoms include the furnace cycling through startup and then shutting down, repeated lockout fault codes, or a visibly cracked or broken igniter element.

  • Specs: Spark electrode / hot surface igniter | OEM Part No. LH33WZ010 | Factory-matched geometry and resistance ratings for precise fitment on Carrier LC3:50LC400677 | Compatible voltage and wattage per Carrier factory specification
  • OEM vs Generic: This OEM igniter meets exact Carrier factory tolerances for element composition, lead wire length, and mounting bracket alignment. Generic igniters frequently use lower-grade silicon carbide materials prone to premature cracking, shorter service life, and mis-matched wattage that can cause nuisance lockouts or incomplete ignition.
  • Install Difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle igniter element only by the ceramic base — skin oils cause hot spots that crack the element prematurely. Typical replacement time: 20–30 minutes.
  • Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day from our warehouse to get your system back online fast.

Compatibility: Engineered specifically for the Carrier LC3:50LC400677 heating system. Always verify your existing part number and model data plate before ordering to ensure correct fitment. Our HVAC parts specialists are available to confirm compatibility before you purchase — don't guess on ignition components. Order today and enjoy same-day shipping on all in-stock OEM parts.

Frequently Asked Questions

Does this Igniter fit my Carrier LC3:50LC400677?
Yes. This is the factory-specified OEM igniter for the Carrier LC3:50LC400677. 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 LC3:50LC400677?
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.
How fast does National HVAC Parts ship?
