LG Electric Range 30'"s/c range - SS Item LRE6321ST model, is defective, something wrong with the electric power panel, flat burners will go up the temperature to a high burning point and will NOT turn down unless the stove is unplugged from the wall, the oven switch can go on but will not turn OFF...Is 100% Hazardous.
LG head office customer service responded to my concern with additional charges for having a technician to fix the problem. The problem here is not a wear and tear is a Manufacturing problem!!!
