Brother You are absolutely right! Used to be real care full in the old days, I have a new panel but never had to install it.
Now I yank that panel out, some times use my steamer to loosen and use foil tape to repair & beef up all surfaces & styrofoam chanels
I remove old foil clean dry good..
I have been using heavy duty AC foil tape and also I use (window or door ) foam insulation 1/2 to1/4 thick. on the sides .
Samsung cheesy foam is worthless.
