OEM Carrier Hot Surface Spark Electrode Igniter LH33WZ018 for Model LC348LC400283

This is the factory OEM hot surface spark electrode igniter (part number LH33WZ018) designed as a direct replacement for the Carrier LC348LC400283 furnace. The igniter is the first critical component in your furnace's ignition sequence — the control board energizes it to reach ignition temperature, allowing the gas valve to open and the burners to light. When the igniter fails, the furnace will attempt a heat cycle, fail to establish a flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the inducer motor running normally but the furnace locking out after one or more ignition attempts with no visible glow at the igniter.

  • Specs: Spark electrode igniter design | OEM part number LH33WZ018 | Factory-matched electrical and mechanical specifications for Carrier LC348LC400283 | Correct bracket geometry and wire harness connector for drop-in installation
  • OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory tolerances. Generic igniters frequently differ in tip geometry, element resistance, and ceramic insulator quality — leading to premature cracking, inconsistent ignition, and shortened service life. OEM ensures first-time reliable light-off every cycle.
  • Install difficulty: 3/5 — Turn off gas supply and 24V 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 premature failure. Photograph existing wiring and bracket orientation before removal.
  • Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier LC348LC400283 furnace. Always verify the OEM part number LH33WZ018 against your unit's data plate or existing igniter before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence and get your heat restored fast.

Frequently Asked Questions

Does this Igniter fit my Carrier LC348LC400283?
Yes. This is the factory-specified OEM igniter for the Carrier LC348LC400283. 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 LC348LC400283?
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?
