Product review (5 stars): Don't know if I actually needed to replace the igniter ...
Don't know if I actually needed to replace the igniter on my dryer, but the cost was next to nothing and I had to replace the flame sensor anyway. With the ease of install and the peace of mind from replacing a part that could have went out on me, it was well worth it. If you're going to be in there replacing anything may as well replace this too.
