OEM Carrier Hot Surface Igniter LH33WZ010 for Model LC350HE400813

This is the factory OEM hot surface igniter (part number LH33WZ010) for the Carrier LC350HE400813 furnace. The igniter is the first active component in the heating sequence — the control board energizes it to glow at temperatures exceeding 1,800°F, igniting the gas burners within seconds. When it fails, the furnace will attempt ignition, fail to light, and enter a safety lockout, leaving your home without heat. Common signs of a failed igniter include a furnace that clicks or runs the inducer but never produces flame, or a visibly cracked and brittle igniter element.

• Specs: OEM Part No. LH33WZ010 | Spark Electrode / Hot Surface Igniter type | Factory-matched electrical characteristics for Carrier LC350HE400813 | Tested to withstand repeated thermal cycling
• OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory specifications. Generic igniters frequently use lower-grade silicon carbide that fractures prematurely or draws incorrect wattage, causing nuisance lockouts and potentially damaging the control board over time.
• Install Difficulty: 2/5 — Turn off gas and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Critical: never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Use gloves or handle only by the ceramic bracket.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.
