Hi, My dryer gets to the end of a cycle and instead of displaying the word "end", it has a square on the display that is chasing itself. This wouldn't be a big deal except for the fact that it doesn't stop the cycle! It will stop drying for a couple of minutes and beep, then start back up, the whole time displaying the square. It seems to be never-ending and if I am not paying attention the dryer will do this for hours. Any ideas of what could be wrong? Thank you so much for your help!
