Product review (4 stars): It works
My dryer has been serviced before with the similar problem.  From that incident, I have learned from the serviceman I have hired what went wrong.  So I decided to give it a try to do it my self for about 1/10 of the cost as hiring a serviceman.  Parts came, opened up the dryer, vaccuumed the dust, bumping around in finding the parts & replace, and it works.  I am not that handy, but I would recommend to buy it and try fixing it yourself.
