Thanks for the question.
You said the blower trips out does the drum keep turning when this happens.
The number 472 and 471 can cause this problem .
Your dryer has two motors one to turn the drum and one to turn the blower .
Replace both those parts it should fix the problem.
Their not motors their sensors that turn off the blower motor and that whats happening with your dryer.Heres the complete breakdown of that dryer to help you.
You said you vacuumed the dust so you must have had the drum out to do that.
Heres the breakdown of that dryer, this will help you to get to the sensors.
Open the door and remove the screws you see this will take the front panel off .
Now you can get to those sensors.
Try the screws on the front with the door open.
This dryer is so new that I have never taken one apart and theres no real info on line about that.
What I will do is unlock your question to me and see if another expert will pick it up.
Meanwhile Ill look for more info for you.
Thanks and God Bless.
