ICP Hot Surface Igniter for WPG3482115RKB1 — OEM Assembly | Ships Today

Overview

This OEM hot surface igniter assembly (part #1175974) is the component that lights the burners in your ICP WPG3482115RKB1 furnace. When the control board calls for heat, line voltage energizes the igniter element, which glows red-hot and ignites the gas as the valve opens. Hot surface igniters are fragile and wear out over time — the silicon-carbide or silicon-nitride element becomes brittle and eventually cracks or fails to reach ignition temperature. A bad igniter is one of the most common causes of no-heat calls. The complete assembly includes the element, mounting bracket, and wire harness for a true plug-and-play replacement.

Specifications

Compatibility

This igniter assembly is the factory-specified ignition component for the ICP WPG3482115RKB1 and is used across many Heil, Tempstar, and Comfortmaker gas furnaces built on the same platform. Match the part number and connector style to confirm fit.

Installation Guide

1. Safety First — Shut off gas and disconnect electrical power, then verify zero voltage with a multimeter at the furnace.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the igniter position and wire routing before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and carefully lift out the old assembly without touching the element.
5. Install — Mount the new igniter, handling it only by the ceramic base (never touch the element), and reconnect the harness.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light.

Signs You Need a Replacement

• Furnace blower runs but there is no heat (no ignition).
• Igniter does not glow when the furnace calls for heat.
• Visible cracks, breaks, or white spots on the element.
