Usually wave guide are not replaceable. It is time to go buy a new microwave oven.
SOURCE: Dacor Microwave
Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.
The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.
It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!
The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.
If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.
Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.
If your waveguide cover is burned, it will need to be replaced.
The part would be much cheaper if you get the Sharp version (these ovens are made by Sharp) instead of the Dacor branded part.
The model DMT2420 is essentially the same as model R440D / R540D.
The Sharp part number is PCOVPB085MRP0 (zero on the end) and you can order Sharp parts from Tritronics at http://www.wehaveparts.com

The Magnetron has failed, causing the waveguide to become damaged. If the waveguide is damaged/burned the microwave can not be repaired and should be replaced.
