ICP Hot Surface Igniter for WPG4604130RKB1 — Furnace Ignition | Ships Today

Overview

This OEM hot surface igniter (part 1177663) and its companion igniter control board (part 1186861) are the factory replacements for the ICP / Tempstar / Heil WPG4604130RKB1 gas furnace. The hot surface igniter is the element that glows orange-hot on each call for heat, lighting the gas at the burners; the control board sequences and powers the ignition. Hot surface igniters are brittle and wear out — repeated heating cycles, oil from bare-hand contact, or vibration crack the element, after which the furnace fails to light. Common symptoms include a furnace that cycles the inducer and gas valve but never ignites, an igniter that no longer glows, or a control lockout after several failed ignition attempts. Replacing the igniter (and board where called for) restores reliable furnace startup.

Specifications

Compatibility

Engineered as the correct replacement for the ICP WPG4604130RKB1 furnace. ICP-built furnaces are also sold under the Tempstar, Heil, Comfortmaker, and Arcoaire labels, so this hot surface igniter and control board service equivalent units across those lines that originally used parts 1177663 and 1186861. Verify your model's ignition style before ordering.

Installation Guide

1. Safety First — Turn off power at the furnace switch and breaker and shut the gas, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment access panel.
3. Document — Photograph the igniter bracket position and wiring before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the new element with bare hands.
5. Install — Mount the new igniter by its bracket only, reconnect the harness, and replace the control board if included.
6. Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light on the first attempt.

Signs You Need a Replacement

• Furnace runs the inducer and opens the gas valve but never ignites.
• Igniter no longer glows or glows weakly.
• Visible cracks or breaks in the igniter element.
