Coolcat cabinet foil tape cracked

Ghannan

The foil tape that seals a seam behind the outside grille is cracked most of the way around the cabinet.  Should I remove the grille, replace the tape and re-caulk the grille?  Is the metal tape really critical?  Photos attached

Same thing happened to mine and last year I had the dealer do just as you said: remove grill, retape with foil, replace and seal. It's been a year and it's still good.
