My dryer wont comeon at all the panel does not light up at all

This is a very common problem with this dryer. It could be one of three things. List below is in order of probable cause:
1.) Bad connection between the interface & Control boards.
2.) Interface board. (Front Bezel with all the buttons)
3.) Control board. (under metal cover top left side of unit)
If it was me unplug unit. Remove 3 each screws on back of unit that hold the top on and remove top. Remove screws and open silver box on top left side. With a small screw driver carefully push in on lock tab and pull 2 each flat cable assembly from control bd. Remove silver crossbar at the top near the from 2 screws. Open door pull out and up on front input display bezel carefully. Same process as before remove all cables and reinstall them back in there original location. Then reassemble in reverse order.
Turn power on this should fix the problem.
If it does not then replace the interface board if that does not work then the control board.
me.
