This was a bit trickier than I thought it would be. First, pile up a stack of books to support the steel door front when it is removed. Next, open the door down onto the the stack of books and then remove all the screws around the perimeter of the door. There are 3 types of torx screws, make sure to note where each goes. Once all the screws are out the steel front will drop down onto the books and you can then remove the control panel so you can see the dispenser. You will need to carefully unplug the connector from dispenser. Use a small screwdriver to pry the tab to the side, it will not come out otherwise. Likewise, carefully pry the plastic harness away. You might need to unplug one connector at the top of the unit so the wiring can be moved out of the way Now the dispenser is ready to be removed, this is the hard part. It is held in place by numerous sharp metal tabs. These have to be moved aside SIMULTANEOUSLY to allow it to pop out. Prying one or two at a time I found, will just waste 20 minutes or so. I used stainless dinner knives (they were handy in the silver drawer) and used one for each tab. Once all the tabs on 3 sides were released, it popped out. I then wiped the flange clean and installed the new one. The seal is very stiff and you will have to press with 10-20 pounds of force around the perimeter to get all the tabs to click into place. Hard part over, it is easy to reverse the wiring / screw steps and put the thing back together.
