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

The ICP OEM Igniter Electrode (part number 1179966) is the direct ignition component for the RGS303LSFA0AAAA gas furnace. This hot surface igniter heats to ignition temperature within seconds to light the burners on each heat call. When an igniter cracks, develops hairline fractures, or burns out, the furnace will fail to ignite, short-cycle, or lock out after several failed trial-for-ignition attempts. Replacing the igniter with the correct OEM electrode restores reliable, safe ignition without nuisance lockouts.
