A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Overview

This genuine OEM igniter electrode (part number 1179966) provides the ignition source that lights the burners in your ICP RGS243LFEA0AAAA furnace. On each heat call the control board sends voltage to the igniter, which heats up and ignites the gas as it leaves the burner. Igniters are brittle and wear out from thermal cycling, cracking or losing the ability to reach ignition temperature. A failed igniter is one of the most common causes of no-heat calls: the inducer runs and the gas valve tries to open, but the burners never light, often locking the furnace out after several failed attempts. Replacing the igniter restores fast, dependable ignition and clears intermittent or hard-start no-heat faults.
