ICP Hot Surface Igniter for WPG3242060RKB1 — Furnace Ignitor Assembly | Ships Today

Overview

This is an OEM hot surface igniter assembly (Part No. 1175974) for the ICP / Tempstar / Heil WPG3242060RKB1 packaged gas unit. The hot surface igniter (HSI) is the component that lights the burners on each heat call. When the control board proves the pressure switch and energizes the igniter, the element glows bright orange and ignites the gas as the valve opens. It is one of the most frequently replaced wear parts in a gas furnace.

Igniters are fragile and degrade with every heating cycle. The silicon carbide or silicon nitride element becomes brittle and eventually cracks, often without any visible damage. A failed igniter is a leading cause of no-heat calls: the inducer runs, the board sequences, but the burners never light and the furnace locks out. Handling the new igniter by its element with bare fingers can leave oils that cause premature failure — always handle it by the ceramic base.

Specifications

Compatibility

Direct OEM replacement for the ICP / Tempstar / Heil WPG3242060RKB1 packaged gas/electric unit and related WPG-series furnaces using igniter assembly 1175974. Confirm the part number and connector/bracket style against your existing igniter before installing.

Installation Guide

1. Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter; shut off the gas if servicing the burner area.
2. Access — Remove the burner/control access panel to reach the igniter at the burner assembly.
3. Document — Photograph the igniter position, bracket, and connector before removing.
4. Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter without bumping the element.
5. Install — Mount the new igniter handling it only by the ceramic base, set it to the correct position over the burner, and reconnect the plug per your photo.
6. Test — Restore power and gas, start a heat call, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Inducer runs and board sequences but burners never ignite.
• Furnace locks out after several failed ignition attempts.
• Igniter element shows cracks, blisters, or no longer glows.
• Open circuit / no continuity measured across the igniter element.
