    Sorry about that. Try clicking on the microwave oven problem under this person's profile page. You were discussing a problem with them. I believe they may me confused with you. They have a follow up question about a waveguide replacement for a Sharp microwave oven.

How do I install a waveguide in a Sharp microwave oven? The old one burned through because of corrosion beneath it. I sanded it & repainted with rust preventative paint. I don't want to break it during...


If you mean the waveguide cover, those are almost always mica or plastic.

They would normally install by sliding them into slots in the cavity or ceiling, and sometimes they are held in pl;ace with a plastic rivet, too.

If a waveguide cover is damaged, it should be replaced with a new one, not repaired in any way.

Arcing will occur, which can damage your magnetron, waveguide, and / or chassis.

If you mean the waveguide itself, which channels the microwave energy from the magnetron to the cooking cavity, that cannot be removed or replaced. They are welded in place. If the waveguide is bad, the oven has to be replaced.

We have quite a few Sharp service manuals which cover disassembly and parts lists, etc. If we have it, I can point you to a link to download it free.

Feel free to contact me directly with your model number.

Sparking


Quite often this is due to grease or food particles stuck somewhere in the cavity of the oven or stuck on or behind the waveguide cover.

It may also be in the area of the turntable support, coupler, or motor.

The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet.

In some models it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.

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 and dried thoroughly.

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. It provides important protection for the magnetron.

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.
