Hi, my microwave GE JVM2070SK02 has been behaving erratically. At first the touch panel responded in random way, say if I press 1 min reheat it would change to cooking option. I unplugged the cord for a minute and it would go back to normal. A couple of days later the display froze and the touch panel would not respond to anything. I unplugged the unit for 1 min and then for over an hour but now it shows the screen that reads power lost... Is it the bad logic board or the touch panel or something else? Thanks a lot for your help!
