You guys are lucky. I just got a new 3580RL(1/2 time ) and the microwave control panel or none of the display will not come on at all. The light inside the oven comes on and power is OK. But the display panel will not show a colon as the manual states. So, we returned it to the dealer who had the factory ups us another one, brand new> Guess what, the display or control panel on the new one will not work either when we plug it into 120. The light inside comes on but the control display do not come one at all. It there something we need to do other than plug it in????or is the faulty ovens from China? Anyone got any advice?/ Please tell us what the problem is and is thid a common problem. When we took the walk around ,the oven control panel was working. But since we got home with it, no luck at all. Need help>
