My dryer is having a odd issue, the dryer works sometimes, but other times it will stop partway through a cycle, or not start at all. When it does not start, holding the timer clockwise, with not enough force to actually turn it, will cause the dryer to run, and sometimes stay running, other times it will stop as soon as I stop holding the timer. If the end of cycle buzzer is on, it will alarm as soon as the dryer stops, no matter where in the cycle it is. It seems to me that the timer is the issue, but when I called the local parts store, they told me the timer is very rarely the issue. I am grateful for any advice.
