OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6D48NG482024

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified replacement for the Carrier N6D48NG482024 packaged gas/electric unit. The igniter is the critical first step in your furnace's ignition sequence — it heats to extreme temperatures to ignite the gas burners on each heating cycle. When the igniter fails or cracks, the control board will detect no flame after the ignition attempt and lock out the system, leaving you with no heat. Common symptoms include the inducer motor running followed by a lockout fault code, or a visibly cracked or broken igniter element.

• Specs: Spark electrode / hot surface igniter | OEM part number LH33WZ010 | Factory-matched geometry and mounting configuration | Rated for continuous thermal cycling
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact material and dimensional specifications. Generic igniters vary in element composition and mounting angle, which can result in misfire, premature cracking, or incompatible connector fit — always a risk on packaged rooftop units where service access is limited.
• Install Difficulty: 3/5 — Shut off gas and electrical power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify continuity on the new igniter before reinstalling the burner assembly. Handle the igniter element only by its ceramic base — skin oils cause hot spots and premature failure.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our climate-controlled warehouse.
