Overview
This genuine OEM hot surface igniter assembly (part number 1175974) is the factory ignition component for the ICP/Tempstar/Heil WPG3362090LKB1 gas furnace. The hot surface igniter receives a low-voltage signal from the furnace control board at the start of each heating cycle, heats to roughly 2,000°F, and ignites the gas as it flows from the burner manifold. It is one of the most frequently replaced wear parts in modern gas furnaces because the brittle silicon-carbide or silicon-nitride element naturally degrades with each ignition cycle. Common failure symptoms include no ignition, a furnace that clicks but never lights, repeated lockouts after three or four ignition attempts, or a visibly cracked, chipped, or no-longer-glowing element. Installing a fresh OEM igniter assembly restores reliable startup and prevents nuisance no-heat calls.

- Access — Remove the burner compartment service panel.
- Document — Photograph the igniter mounting and wire routing before disconnecting anything.
- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter, handling it only by the ceramic base, and reconnect the harness per your photo.
- Test — Restore gas and power, then run a full heat cycle and confirm the igniter glows and the burners light.
