Hello, I have a very good fridge of Dometic, type RML9335 installed in my camper. Unfortunately, the flat angle that takes up the door hinge is loose. This flat angle is mounted above the refrigerator with three screws concealed. And these screws are loose. It’s not about the actual hinge of the refrigerator door. You can hardly (not) join these 3 screws. If you expand the control unit above the refrigerator, a flat shaft opens. The flat angle is visible and you can also touch the screws. However, it is so flat that you can’t handle it and certainly not if you don’t know the type of screws. Therefore… 1. Who knows what kind of screws it is? 2. Does anyone know how to extend the plastic cover over the cooling tank? This plastic cover takes up the control unit that I have removed (see pictures). I am grateful for any help.
