This OEM Carrier hot surface igniter (LH33ZS003) is the component that lights the burners on your N6A48NG481452 gas furnace. When the control board calls for heat, the igniter glows red-hot to ignite the gas as the valve opens. Silicon nitride igniters like this one are durable but eventually crack or burn out from thermal cycling, leaving you with a furnace that clicks and runs the inducer but produces no heat. This genuine replacement delivers fast, consistent ignition and is built to Carrier's exact resistance and mounting specifications for a true direct fit. Installation is easy and usually takes 15-20 minutes: shut off power and gas, unplug the old igniter connector, remove the mounting screw, and set the fragile new element in place without touching the ceramic surface. Most homeowners can handle this repair with basic tools. Get reliable, on-demand heat restored quickly with a part made to last. Orders placed before 3PM CST ship same-day. In stock and ready to ship today.
