HI FOLKS, It happens the same many years ago with a fifties Norge fridge. I called a technician in fridges, and he tied an electric cable, in green colour, and fitted it to a new plug which was earthed, like the electric socket in the wall. That worked indeed. Years later there was a short circuit with a transfo from 110 to 220 volts, the Norge was made in USA, of course, and here we have 220 volt current. And all the fridge was energized with a pole of 220 volt, so I moved the fridge and when I replaced it, it refused to start, and then I discovered the short and see sparks on the screw where the cable was attached. That saved my life! After that I ALWAYS attach a green cable where there´s no earth. ONE MAIN ITEM the wall receptacle MUST BE PROPERLY EARTHED. That´s my cent! Take care with electricity. Good luck.
