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.

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.

Please write back with your brand and model number if you need further help.

Microwace noise coming from top and flashing


dont use the microwave until you retrieve what dropped inside when you removed the port. The grinding is most likely a foreign object that is hitting the moving parts of the microwave and causing sparking. It can catch fire

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

I have an over-the-range microwave. When cooking on the stove surface, as steam hits the microwave, it will suddenly turn on. Occasionally you can reset, but usually has to be unplugged to make it work...


That will be caused by condensation affecting the controls of the microwave oven. Not a lot can be done about that except cut down on the steam maybe or wait for the temperature to rise slightly avoiding the condenation problem.

Sienens microwave HFT879 fault


Exactly the same problem over here, but after our house was hit by lightning, so not really surprised about the cause of the problem. If you look closely, you can still see the displays on a very low light level. I can still choose a microwave program, turn the time etc, and see the time changing, but start won't just just work.
