Diffuser started clicking and would not regulate the cold air from the freezer section into the coldbox section. Vegtables kept freezing.

One screw inside the refrigerator removed the cover exposing the diffuser assembly. I had to also remove the cover inside the freezer compartment in order to free the diffuser assemble bracket that protruded in from the refrigerator compartment directly on the other side. Once the diffuser was freed, the assembly came off in my hand. The new one just snapped back in place. Done.
