I have a GE compactor model gcg1580lss. The other day when wife ran it, after ram cycled down then back up, it continued running, with ram in top position, and began to vibrate. It did not recycle, just stayed in top position. In order to shut it off, I can open the drawer and shut switch. If I turn switch back on and close the drawer, it will immediately cycle through again, ram up/down, but again continues running with ram staying up. Any ideas? Thanks.
