I appreciate your post, philip hunter!

From my understanding the control panel on your Electrolux range is locked. On the control panel you should see a button near a lock symbol, typically it is labeled control lock, and if you hold that button down for three to five second it should release the control panel. If that does not help release the panel I would suggest performing a reset and you can do that by disconnecting the power from your range for ten minutes. Hopefully this helps. -Matt
