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 a genuine OEM igniter electrode, part number 1179966, for ICP / Tempstar / Heil RGS303LTFA0AAAA gas furnaces. The ignition electrode is responsible for lighting the burner at the start of every heat cycle. Over time the electrode tip erodes, cracks, or accumulates carbon and corrosion, which weakens the spark or hot-surface ignition and leads to delayed ignition, rough light-off, or repeated ignition lockouts. Because the furnace will not produce heat without reliable ignition, a failing electrode is one of the most common no-heat service calls. Installing a fresh OEM electrode restores consistent, on-demand ignition and the correct gap geometry the furnace was designed around.
