When I replace the oven control board # 31607511 Do I have to buy a seperate overlay for it?
I see on some boards you can reuse the old one.
The part number for the Overlay on your unit is part number 316220805. You can try to reuse the overlay but may need to replace it as the stickiness on it may not hold.
You can't see the temperature reading to set it.
The model number listed is not coming in as valid or may be incomplete. We would need to have the model number to be able to assist properly. Please post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx
