Thank you for your request for instructions on changing the oven control.
I assume you are referring to the electronic oven and clock control up in the console control panel.
First disconnect all power to the range. Side the range out from the wall and remove the top back panel from the range.
Then locate the back side of the electronic control and remove the four screws that retain the control into the control panel. With the new replacement control in hand move the wire harnesses from the old control to the new control one at a time. Any single wires that may be on the control replace one at a time.
Once you have all the wires changed over to the new control, position the control into the control panel and fasten with the screws you previously removed.
Then reattach the back panel and test operation before sliding it back into position.
I hope these instructions were complete enough for you to accomplish this repair.
