ICP Furnace Control Board & Ignition Module for WPG3364060LKC1 | Ships Today

Overview

This OEM furnace control board (ICP part #1178358) with integrated ignition control module (part #1177661) is the brain of your ICP/Tempstar/Heil WPG3364060LKC1 gas furnace. It sequences the entire heat cycle — energizing the inducer, verifying the pressure switch, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower. When the board fails you'll see erratic operation, no ignition, blower running constantly, or flashing diagnostic fault codes. Installing the exact OEM board ensures correct timing, flame-sense sensitivity, and safety logic.
