OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6A48NG482021

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified spark electrode ignitor for the Carrier N6A48NG482021 packaged gas/electric unit. The igniter is the first critical component in the heating sequence — it glows to ignition temperature to light the burner assembly. When it fails, the control board will attempt ignition, detect no flame, and lock out the furnace, leaving you with a no-heat call and a blinking fault code. A cracked, broken, or worn igniter is one of the most common causes of heating failure in packaged units.

• Specs: Spark electrode ignitor design | OEM part number LH33WZ010 | Factory-matched geometry and electrical resistance | Rated for Carrier packaged gas/electric applications
• OEM vs Generic: This is a genuine OEM Carrier igniter — not an aftermarket substitute. Generic igniters frequently differ in mounting angle, element length, or resistance tolerance, causing nuisance lockouts or premature failure. The OEM part ensures proper flame positioning and full control board compatibility.
• Install Difficulty: 3/5 — Turn off gas supply and 240V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves. Handle the igniter element with care — skin oils will cause premature cracking. Do NOT touch the ceramic or element with bare hands.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our climate-controlled warehouse.
