OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6A48NG482015

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified replacement for the Carrier N6A48NG482015 packaged gas unit. The igniter is the critical first step in every heating cycle — it glows red-hot to ignite the gas burners on call for heat. When it fails, the control board will detect no flame establishment and trigger a lockout fault, leaving you with a system that attempts ignition, fails after one or two tries, and shuts down entirely. Common symptoms include a cold air complaint with a flashing fault code indicating ignition failure.

• Specs: Spark electrode / hot surface igniter | OEM part number LH33WZ010 | Factory-matched geometry and element rating for Carrier N6A48NG482015 packaged gas units | Silicon nitride or silicon carbide element per OEM specification
• OEM vs Generic: OEM igniters are manufactured to exact element resistance and bracket tolerances. Generic igniters often vary in tip geometry and current draw, leading to nuisance lockouts or premature cracking — especially on cold starts where thermal stress is highest.
• Install difficulty: 2/5 — Always shut off gas and power before servicing. Allow the old igniter to cool completely before handling. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Do NOT touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Use gloves or handle by the ceramic base only.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse — no backorder delays.

Verify your existing igniter part number against LH33WZ010 and confirm bracket style matches before installation. If you are unsure of fitment, our HVAC parts specialists can verify compatibility before you order — no guesswork, no returns.
