That would be your waveguide cover. If damaged or discolored, the waveguide cover has been damaged by heat and must be replaced.
It protects your waveguide and magnetron from arcing due to grease and food particles.
The area of the waveguide behind the waveguide cover should be clean, and if rust or flaking is present it must be sanded, then repainted with high temperature appliance paint.
For Dacor model DMT2420S, the waveguide is part number 66345 and you can get it from The Pros here for $11.07 (subject to change).
The service manual is at my site here: http://www.microwavecontrol.com/dmt_2420_sm.pdf and the part list is here: http://www.microwavecontrol.com/dmt_2420_parts_list.pdf.
