Dec 18, 2019 at 17:21 comment added kenneth Thanks so much for replying. I will take some pictures tonight when I get home. There are 2 (large) panels on the side of the unit with screws I removed all of the screws on both panels. The one panel I was able to remove only shows the copper coils and no circuit board. The other panel has some black press-on adhesive that is very strong and holding the panel in place. When I tried to pry it apart the panel actually started to bend or crimp, so I stopped. I thought the black adhesive was a sign that the panel was not intended to be removed.That's why I decided to write and ask for some advice
