Sparks inside a wolf mw24 inside in right wall cover plate


The right side wall cover plate is the "waveguide cover."

It protects the waveguide and the magnetron at the other end from moisture, grease, and food particles.

If these remain stuck to the waveguide cover, arcing can occur, which will damage and / or destroy the cover, the waveguide or even the magnetron or the oven chassis.

As with most problems, this should be addressed sooner rather than later or it will only get worse, and may become unrepairable.

The similar Sharp model R-530E-series service manuals are here and here. They will help with disassembly, but the external / cosmetic parts will not interchange.

The Wolf waveguide number is 801798 and Wolf part ordering information is here.

The oven cavity and waveguide must be clean and if any spot is scorched or chipped, it must be sanded smooth, cleaned and dried, then touched up with appliance paint, available from local big box stores, home centers, appliance parts stores, and hardware stores.

Leave the door open overnight to dry the paint. Then install the new waveguide cover.

If the chassis or waveguide have holes in them, the oven must be scrapped and replaced.

For more free DIY and other help & advice, feel free to contact me via my site.

Please include FULL model number*, FCC ID number*, + detailed symptom information. ( * on the tag in cooking cavity or around door frame or control frame or on back)

Dacor DMT2420S


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.

I have a Sharp Carousel Microwave R-1460A. The disk on the ceiling, opposite the warming plate and about the same size, has severe burn marks (probably from food splatters). Any idea what that part is


see this indication and fix it. God bless you
  1. Waveguide coverSparking and arcing in a microwave can be caused by a damaged waveguide cover. Try removing the waveguide cover to see if the problem persists. Once removed, the waveguide cover can be inspected for burns, which will indicate if this is the issue. If the waveguide cover is burnt or will not stay in the proper spot it will need to be replaced.
  2. Cavity/Rack supportIf sparking or arcing in your microwave is near a rack support, any exposed metallic area can be covered with a microwave cavity support. It is also recommended to replace the rack supports in this situation to ensure the issue is resolved.
  3. Cavity paintIf sparking or arcing in the microwave is visible on the side walls, the paint covering the metallic areas could have worn off or chipped. This can possibly cause pitting in the side walls or ceiling. If this is the case, it can be repaired with microwave cavity pain

    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.
