My dryer works fine on Medium and Fluff but not on Regular heat. When we want to use regular heat we have to spin the drum and turn the on switch at the same time...it works fine after that but just won't start up on its on when on regular heat.

For clarification: it will start up by its-self on medium and fluff but will not start by its-self on regular heat.

update to the update....dried a load on medium heat, then attempted to dry a load on regular heat and the dryer is running fine...any ideas on what could cause this?
