Why would changing a light bulb cause the oven heat and control to fail

ovenrepair

I recently replaced the bulb on my oven. However I did put back the insulating looking ring. I pushed the oven light button while baking nachos. I heard a pop and the heat went out as did the light and digital display that shows temp, time… The burners still work though. New wires inside needed? New fuse? Can someone please help!

Since you mentioned an insulating ring and every thing was fine until you turned on the light there is a short in the wiring (the pop) was something going to ground. Hopefully there is a fuse but some damage to the wiring or control board is likely if not fused inside the controller. With the power off look for a fuse and or blown traces on the controller.
