OEM Carrier Hot Surface Igniter LH33WZ010 for Model LC350HE401224

This is the genuine OEM hot surface igniter (part number LH33WZ010) for the Carrier LC350HE401224 furnace. The igniter is the first component in the burner sequence — the control board energizes it to reach ignition temperature before opening the gas valve. When the igniter fails or cracks, the furnace will attempt a light cycle, fail to establish flame, and lock out after 2–3 tries. You'll typically see a fault code indicating "ignition failure" or "lockout" on the control board's LED display.
