I did reasearch, like everyone else has, to only find out the dispenser had to be replaced. No diagrams of any value. Start a fire in the kitchen, it's easier to deal with! The locking tabs are located at the top and bottom inch on both sides for the cover and screen. After that drama, change was a breeze. All in all, the swap out was a success. It took me almost an hour for a 10 min task because of the hidden tabs.
