What could possibly be wrong?? When I am using the permanent press cycle and the dryer stops after the cool down period I will open the door and find clothes dry at the right temperature. Then somtimes I open the door (on the same setting) and the clothes are so hot that they could burn your hand. What might I need to replace or check??
I would check that the blower wheel is clean and properly attached to the motor shaft.
If OK
I would replace the cycling thermostat.
