2nd service call in 2 weeks normal cycle running, then halfway thru, beeping beeping, try to open with hitting it twice on front panel, nothing, drawers won't open.  Had to unplug.  Child lock was not engaged as I double check that now as this was one of the issues last time.  The display isn't easily to operate as it moves very slowly as you make your selection..sometimes it moves and sometimes it hesitates, of course when the repair tech comes he will say it works fine.  Turned it off at breaker, now I wait for the  thing to reset, service tech will come Monday.  What is wrong with these machines!!!!!!! Had GE in house before but I didn't have the drawer, love the look, hate the performance and constant beeping.  Child lock should be an option, this is absolutely a ridiculous item.
