My dryer was working but would take all day to dry a load of clothes, so my husband went online to try and diagnose the problem, and figured out the Dryer Thermal Fuse was probably bad, which was why the dryer was working but no heat.  We looked for part locally but couldn't find one, so ordered through Amazon and had our dryer working again in just a few days and much cheaper than a new dryer or repair man. It was easy to replace!
