OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6D48NG480100

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified spark electrode ignitor for the Carrier N6D48NG480100 packaged gas unit. The igniter is responsible for generating the heat or spark necessary to light the burners during each heating cycle. When it fails, the furnace or packaged unit will attempt ignition, fail to establish a flame, and enter a safety lockout — leaving you with no heat and a blinking fault code on the control board. Replacing the igniter is one of the most common furnace repairs and restores normal heating operation quickly.

• Specs: OEM part number LH33WZ010 | Spark electrode ignitor design | Factory-matched fit and geometry for Carrier N6D48NG480100 | Rated for repeated high-cycle thermal stress
• OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory tolerances. Generic igniters vary in electrode gap, mounting dimensions, and ceramic insulator quality — increasing the risk of premature cracking, misfire, or improper flame sensing that can cause repeated lockouts.
• Install difficulty: 2/5 — Turn off gas supply and disconnect power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Handle the igniter ceramic body carefully — skin oils can cause premature failure. Always verify the fault code is igniter-related before replacement.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
