Learn how your appliance is supposed to operate so you can determine if it is malfunctioning.
Ignitors are constructed of metals that have significant resistance to the flow of electric current. Ignitors reach temperatures as high as 2000 degrees F or more. The constant heating and cooling can fatigue the metal until it cracks and breaks. This process limits the life of an ignitor. This is the reason why the ignitor is the most likely component to fail in a gas dryer burner assembly.The following figure shows a failure crack in a round ignitor.
The other type of ignitor has a flat blade as shown in the following figure.Note the two cracks leading to its failure.
Use the appliance model number to order the correct replacement ignitor.
