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

This is the genuine ICP/Tempstar/Heil igniter electrode (OEM part number 1179966) for the RGS243LEAA0AAAA gas furnace. The igniter electrode produces the spark or hot surface needed to light the burner on every heating cycle. Because it is repeatedly heated and cooled, the igniter is a common wear item — a cracked element or eroded electrode tip is one of the leading causes of no-heat calls. Installing a fresh OEM igniter restores reliable, fast ignition.
