OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6D48NG482029

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified spark electrode ignitor for the Carrier N6D48NG482029 packaged gas/electric unit. The igniter is the critical component that generates the heat necessary to light the burner during each heating cycle. When it fails, the furnace or packaged unit will attempt ignition, fail to light the burners, and enter a safety lockout — leaving you with no heat. Common failure symptoms include a furnace that clicks or attempts to start but shuts off after 15–30 seconds, repeated lockout fault codes, or a visibly cracked or broken igniter element.

• Specs: Spark electrode ignitor | OEM part number LH33WZ010 | Factory-matched geometry and resistance rating | Designed for Carrier packaged gas units
• OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory specifications. Generic igniters often differ in element length, mounting angle, or resistance tolerance — causing misfire, premature burnout, or repeated lockout. OEM ensures first-time reliability.
• Install Difficulty: 3/5 — Gas appliance work requires care. Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" and 5/16" nut drivers, multimeter (to verify open-circuit resistance, typically 40–90 ohms), and work gloves. Never touch the ceramic or silicon element with bare hands — skin oils cause premature failure. Photograph wiring and element position before removal.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our climate-controlled warehouse.
