I have Dacor dual convection/self-cleaning ovens. the light bulb burned out in the top oven. I tried to replaxce it but I mistakenly removed the screws holding the light assembly to the top of the oven and now I am unable to replace the light assembly. there are burn marks on the part where the light bulb is screwed in. My nephew thinks I need a new transformer. the glass cover is OK.

Is this what I need and how do you install the new light assembly parts?
