OEM Carrier Hot Surface Igniter LH33WZ010 for Model LC350HE400801

This is the OEM factory-specified hot surface igniter (part number LH33WZ010) for the Carrier LC350HE400801 furnace. The igniter is a critical component in the heating sequence — when your thermostat calls for heat, the control board energizes the igniter to reach operating temperature before the gas valve opens. A failed igniter typically causes the furnace to attempt ignition, fail to light, and enter a safety lockout, leaving your home without heat. If your furnace is cycling through ignition attempts and locking out, or if visual inspection reveals a cracked or broken element, this OEM igniter is your direct replacement.

  • Specs: Spark electrode / hot surface igniter | OEM part number LH33WZ010 | Factory-matched geometry and mounting configuration for Carrier LC350HE400801 | Rated for long-cycle durability
  • OEM vs Generic: This is a genuine Carrier OEM igniter built to exact factory tolerances. Generic igniters often differ in element resistance, tip geometry, or mounting dimensions — any of which can cause nuisance lockouts or premature failure. OEM is always the recommended choice for reliable ignition.
  • Install difficulty: 3/5 — Turn off gas supply and 120V power before beginning. Tools needed: 1/4" nut driver, Phillips screwdriver, needle-nose pliers. Handle the igniter element with care — oils from bare hands can cause premature burnout. Never touch the ceramic or element tip directly.
  • Warranty: 1-year OEM factory warranty. Orders placed by 3 PM ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model LC350HE400801. Before ordering, confirm the part number on your existing igniter or cross-reference your furnace's wiring diagram. Our parts specialists are available to verify fitment — just reach out before you order. In stock and ready to ship today.

Frequently Asked Questions

Does this Igniter fit my Carrier LC350HE400801?
Yes. This is the factory-specified OEM igniter for the Carrier LC350HE400801. 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 LC350HE400801?
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.
