SOURCE: Sparks when in use

Sonja, I'm not sure what hinges you're speaking about. If you are referring to the bumpers on the ends of the wire racks that are used for convection...move the racks away from the wall. Generally, you should not have anything metal in the unit when it is just microwaving....they are for convection use. You will not start a fire but you will shorten the life of the magnetron if you continue to allow the sparking condition.

I would recommend changing the diodes as well. This will usually take care of the problem.

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.

Chances are you have a bad stirrer motor or the stirrer blade is jamming or loose on the motor shaft.

Your owner's manual should tell you how to remove the stirrer cover to check it.

If for some reason you don't have your owner's manual, you can download it free here, as well as the parts manual for your model.

You can also find helpful exploded view diagrams and order parts by entering your full model number here.

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.

They are 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 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.

Loud noise when cooking


I had an arcing sound coming from above the cardboard panel inside the microwave. When I saw it sparking I took the cover off and saw that these two aluminum looking things had come loose. I removed the cover and did a fair bit of 'fine tuning' to get it working again.

Our kitchenaid microwave, sparks when we turn it on.


If the sparks are happening on the inside of the microwave's cooking area while you are cooking, then make sure you clean the inner surfaces really well. Be sure to remove any cooked on food particles that may have splashed up during cooking.

If the cleaning does not work, you may need to replace the waveguide cover. Click on the following Youtube video link for an instructional video on the process:

If the sparks are coming from somewhere other that the cooking area, then your unit may need more significant electrical repairs or service.

Thank you very much and good luck.

KitchenAid Model: KHHS179L Serial No: TR3314099 Experiencing heavy sparking. Where is Wave Guide cover, and how to replace it if necessary. Oven is mounted above stove and too heavy for this old man...


In your owner's manual (available free online here) this is called the "microwave inlet cover".

See the tag in your oven cooking cavity or near the door frame for your full model number.

The cover is located in the ceiling of the oven.

You should be able to remove and clean or replace the cover without removing the oven from the wall.

The oven installation instructions and parts list are also on that page.

You can also find handy exploded views and order any needed parts and accessories by model or part number here.
