hi there, slight problem moved into a flat, the electric oven is old id say a good 10 years, was using it the other day. There seemed to be a slight lingering smell of burning, turns out the plug had completely melted. The oven has a normal 3 pin plug which was plugged into a normal extension, which was plugged into a normal power point, i dont know much about electrics, but is this safe? also, i removed the old melted plug, i dont know if the fuse had blown, but my guess is it hadnt as surely it would have cut in, i would greatly appreciate feedback.
