I have a Kenmore electric dryer model #11062054100 that is almost 2 years old. A few months ago the electronic display board would beep and show 54 minutes and various settings. If you press "off", it clears but it comes back on in a few minutes. The drum doesn't turn when this happens but it just keeps beeping every few minutes. ***** came out twice to fix it. The first time they replaced the thermister. That didn't work. Then they replaced the whole control panel. It worked for a few months but now it has started again. HELP!
