Westley B Lansing , MI November 21, 2016 My samsung microwave was not working and showed a "5e" error Some internet appliance pundits suggested a remove, clean and replace the cables to the touch pad solution. At first I thought this worked, but the problem came right back. Further investigation revealed that problem to be an intermitent one and touchpad replacement was the only solution. Once Ihad the replacement part the job was done in 10 minutes. Less time than it would have taken to pull it off the wall to take it in!
