Ok to remove the top, pull out the lint trap, and remove the two screws located there.
Using a stiff putty knife, or a thin flat bar pry up on the front right, and left corners of the top cover. Raise it back, and lean it against a wall.
Thats all there is to it.
Well that sure puts a monky wrench in the middle of things now dont it.
Give me a few minuits and I'll double check the manual, and your model number.
Ok is it possible that the model number is XXXXX and not MGD?
All right then.
Here are the instruction sheets for your model.
