I live in a large block of flats and the sockets have already been burned. Now, however, I have a strange problem. When I turn on the electric kettle in the kitchen, I can feel the smell in the room clearly coming from one of the sockets. In addition, the socket is warm for a moment. However, on the same socket you can not see even a trace of burning, the equipment connected to it works properly. Of course, now I have nothing to connect to. The question - which of these sockets is really defective, is it enough to replace it "smelly" or also in the kitchen? Could something "burn deeper" have been burning (since there are no traces on the socket itself). Do I have to replace it immediately or can it wait a week? (assuming I will not use the kettle), because I do not have time to deal with the electrics. I will add that there is wallpaper on the wall. And I'm afraid for the safety of other equipment at home.
