I first noticed the problem when after drying a load for about 50 minutes. After noticing the clothes were still damp I would want to start the dryer again but the timer/start button would just buzz and the machine would not start. I would check periodically and eventually the machine would start after maybe 2 or 3 hours. Yesterday I tried to start the machine with a load of towels in it and the machine would just give me a buzzing noise. I opened the lid of the dryer just to see if everything looked alright inside. So I tried again to start the machine turning the drum by hand, it started with a little buzzing noise but it eventually started turning on it's own. After about 30 minutes running the dryer started to make a slight buzzing noise getting louder and louder until the machine shut itself off. Any help would be appreciated to diagnose the problem with my dryer.
