ICP Hot Surface Igniter for WPG4424090LKA1 — w/ Control Board | Ships Today

Overview

This OEM hot surface igniter (OEM #1177663) and matching ignition control board (OEM #1186861) handle the heating ignition sequence for your ICP WPG4424090LKA1 packaged gas/electric unit. On a call for heat, the control board energizes the igniter, which glows hot to light the burners, then monitors flame and gas-valve timing. A cracked or worn igniter is the leading cause of no-heat calls — the unit cycles, the inducer runs, but the burners never light.

Installation Guide

1. Safety First — Disconnect electrical power and shut off the gas supply, then verify zero voltage with a multimeter.
2. Access — Remove the service panel to reach the burner assembly and control board.
3. Document — Photograph the igniter mounting and every board connector before disconnecting.
4. Remove — Unplug and unscrew the old igniter (handle by the base only — never touch the element), and unclip the old control board.
5. Install — Mount the new igniter and board, then reconnect all leads per your photo.
6. Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and burners light.
