OEM Carrier Hot Surface Igniter LH33WZ010 for Model N6A48NG482016

This OEM hot surface igniter (part number LH33WZ010) is the factory-specified spark electrode ignitor for the Carrier N6A48NG482016 packaged gas/electric unit. The igniter is the first critical link in your furnace's ignition sequence — it heats to extreme temperatures to ignite the incoming gas before the flame sensor confirms combustion. When this part fails, the control board will attempt ignition, find no flame, and lock out the system, leaving you with no heat. Common symptoms include a furnace that cycles repeatedly without lighting, error codes indicating ignition failure, or a visibly cracked/broken igniter element.

• Specs: OEM Part No. LH33WZ010 | Spark electrode ignitor design | Factory-matched electrical resistance and tip geometry | 120V input | Engineered for Carrier N6A48NG482016 operating conditions

Handle the igniter element with care — skin oils can cause premature failure. Do not touch the ceramic tip. Photograph existing wiring harness routing before disconnecting.
