A different possibility is the ignitor sensor being dirty. This sensor alerts the ignitor when it's safe to begin working. Therefore, if it gets dirty it will prevent the ignitor from starting. If you observe this happening and you notice this, you must call for a professional to wash the sensor before replacing the sensor.
Experts are able to determine the dimensions of the ignitor to fit your furnace. If the ignitor you are using is that is too small or large to your furnace, the power will not be correct and it may burn out very quickly. A professional can check the ignitor with a tool called a multimeter. It will tell you whether it's the right voltage.
There may be a need to replace the ignitor if it is damaged or too old. The ignitor should be inspected by an expert, since they'll guide you to the appropriate replacement.
