The dryer will run perfectly for about 20-35 minutes the first time you use it. It will shut off (stop tumbling and heating) after that and will not let you restart it for about 10 minutes. Once you restart it, it will only run for about 5-10 minutes and then shut off again. The vent hose was blocked when I took the vent hose off and thought that was the issue, I cleaned out the vent, around the motor and heating element, out of the vent, under the lint catcher... everything, it did not fix the problem. The last time I tried it I realized that the timer isn't moving. If I set it at 50 minutes, it will run for 35 minutes but show 40 minutes still remaining on the timer. More dry setting will move slightly but not much. Is the problem the timer motor or can there still be something else going on?
