Mike for Model Number J KP90S P4SS Suddenly out of blue No Previous Warning ... Get 3 long beeps and the display message "Service May Be Required... Keyboard Short". Sound simple... but do I need "Control Panel" AP5318919 AND "Main Control Board AP4508655 ? Seems strange that the keyboard would "short" when nobody touched it for several days.. This is why I am asking if "main control board" has something to do with it since looks like that is where all the capacitors and bains of this unit is housed....
Answer Mike, This issue would be caused by a shorted key in the key panel/control panel WB27T11340. It is possible that is something that was on its way out and finally gave way to short out. Read More... Answered by AppliancePartsPros.com | Monday, July 20, 2020
