turn dryer on runs fine for a while then just stops, the timmer continues running but dry won't. Replaced the controle board not more than 6 months ago, because it would'nt start at all then. Now it starts but won't stay running. Kenmore model# 25368801791
A motor on it's way out could do this. A motor can run and then heat up and shut off on its internal overload switch. Once the motor cools a bit, it will run again only to heat up and repeat the process of shutting off again.
