Carrier LH33WZ019 Ignitor Assembly 319848-301 Durable Construction: Heavy-duty metal alloyThe Carrier LH33WZ019 Ignitor Assembly is a critical OEM replacement component designed for precise ignition sequences in Carrier, Bryant, and Payne gas fired furnaces. This hot surface ignitor (HSI) is engineered with high grade silicon carbide to withstand rapid thermal cycling and high temperature environments. It functions by reaching necessary ignition temperatures via electrical resistance before the gas valve opens, ensuring a reliable flame
