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. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

The OEM 1179966 ignitor electrode is the hot surface igniter for the ICP / Tempstar / Heil RGS243LSFA0AAAA gas furnace. On each heat call, the control board energizes the igniter and its element glows white-hot to light the burners. Hot surface igniters are brittle and have a finite number of cycles before the element cracks or burns through. A failed igniter is one of the most common no-heat causes: the furnace runs through its inducer and pre-purge but never lights, then locks out. Because the element is fragile, even a hairline crack from a bump or thermal stress can end its service life.
