Our dryer timer has been having problems - the model number is MDG8400AWW. When starting a cycle, the timer is set and then pulled to start. However, it is getting difficult to pull start now - I was wondering if there was a way to open up the timer and repair whatever is causing this. I am assuming that something may just be out of adjustment? I attached a photo of what the timer looks like, it seems to have tabs on it so I assume it is easy to open.
