I have a Kenmore 30" slide-in range (model# 629.46799895). The buttons on the right side of the control board (clock, timer, and up/down arrows) don't respond when pressed. I disconnected, then reconnected the flat flex ribbon behind the control board. This temporarily fixes the issue for about 2-7 days before the buttons stop working again. I'm not sure if I need to replace the entire electronic control board (5760M205-60). Does anyone have any recommendations for a more permanent fix? Any suggestions would be greatly appreciated.
