Can you please tell me how I can get access to the control board and test and replace the control/display board?
Thank you in advance,

Below is removal instruction.
Your model number didn't show up for parts/schematics to reference.
That said, most systems have similar access points.
First, disconnect power supply, it can and will kill you if you try to access service area with power connected and you ground yourself while contacting a hot lead.
FOR DOUBLE OVEN=======================================
IF, your model is a wall double oven which is one large assembly, start by removing doors then removing racks.
Verify you fully turned off power.
Then remove trim peices along the vertical sides and at the base.
At this stage, you should be able to slide oven out of wall opening part way and see the control panel retaining screws/brackets etc.
TAKE PICTURES BEFORE YOU DISCONNECT WIRING HARNESSES.
=====================================================
For range==============================================
Verify you turned off power supply.
slide unit out of countertop area. Access to control is usually from the back side.
Some brands, the side cover plates of the control panel riser are removed from the sides, then the control riser rotates forward exposing the internals.
