Hi I,m John I will help you with the dryer problem,Is this a gas dryer,send me the model number please .
How long do you have to wait before you can restart and get heat ?
once it cools down you can restart it will say drying damp
does the dryer run with heat when it says that ?
when it has heat it says drying
And you get the rattling every time you turn on the dryer ?
only when the heat kicks out yes when the heat kicks out
the parts that can cause that problem are the two gas solenoids located on the gas valve,i will send you the part number .
a rating of three or more will credit me for helping with the dryer problem .
