I can't turn on the oven without operating Manual. I have a drop in oven and glass range top. It's a Magic Chef 5898VRV. The on off, temperature, set clear, bake time, broil, and it's digital, electric 220v. To on right, you need to push a series of buttons. The owner Manual is to turn on bake. The oven range was purchased in 1994.,. Parts replaced, digital touch board, bake element. Brad Clark 6799 E Hwy 12 Lodi California 95240 2097476725
