Similar to cases already listed my stove started “beep talking by itself”. I'm the only person in the house so no one could have set the timer or push buttons. Even after I pressed “Cancel“ button it stopped for awhile only to come back again - with or without displaying F11 ERR code. I unplugged the stove overnight, plugged it back the next day just to have the same problem re-appear. None of the commands on the panel are functional- timer, clock, oven, self clean…. However, buttons and cooktop plates are working. I just bought the place and do not know how old appliances are. However, they look new. Model CGEF3034MFD; serial# VF25169319. Please, advise! Thank you!
