Electronic display was too dim to read and the top baking element was burned out.

I removed two screws to take the control panel off.
The electronic display is held in place with four screws which are easily removed with a nut driver.
The wiring work is extremely simple.
To replace the element, I removed the oven racks, took two screws out, disconnected the two wires, then replaced the element by reversing the process.
Both jobs took less than 20 minutes and that includes two trips to the breaker box in the basement.
