It is not unusual to see your meter spin rapidly when you run an electric dryer, especially at startup.. It will also do this if you turn on an electric oven and 2 or 3 stovetop elements at the same time... Does it seem like it's taking longer to dry your clothes? You did not list the model number of your kenmore dryer but if it's one of the older models made by whirlpool then you may have worn drum felt seals... Or the most common ailment of a lint clogged exhaust hose... Both reduce the amount of heated air flowing thru the drum hence more time needed to dry your clothes and higher electrical use...
