This should explain it:
"Furnace hot surface ignitors are found on most modern furnaces to light the gas flames upon unit start-up. Electricity passes through the Silicon Carbide or the newer Silicon Nitride ignitor and makes it glow red hot. Operating under normal conditions a hot surface ignitor will last for 3 to 5 years (Silicone Nitride lasts about twice as long). During that time ignitors will eventually crack and need to be replaced. Like a light bulb, they are a regular replacement item. Most ignitors are interchangeable as long as they fit in the furnace space provided."

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.
