we have a belling synergie built in oven. the main oven door with the handle is held on by 2 screws at the top and by adhesive at the bottom where it's bonded to 2 metal hinges. The bond at the bottom has gone and the door is now only connected/held on by the two screws. I've tried a couuple of adhesive compounds but neither have worked beyound a couple of days. Does anyone know of a good adhesive that will do the trick?
