I've just cleaned our Panasonic NN-811A Combo Microwave and noted that the door glass/cover has become misty and on the interior surface by the looks of it. I can see no way of getting at this, removing the two door screws on the latch side doesn't allow one to get access as far as I can see.
Two questions: 1) isn't it a bit odd that this should happen? 2) any suggestions?
