If the problem with your Whirlpool 27 inch electric dryer is that the motor runs, but the drum is not tumbling. The problem could be a stretched or a broken belt.
The belt is about ¼ of an inch wide, but it works very hard to keep tumbling the clothes. If the drum won’t tumble the clothes, the clothes are not going to dry properly.
