proceed according. God bless youIf you see arcing or sparking inside a microwave, turn unit off immediately. Arcing can be caused by having something metal in the oven cavity touching a side, an oven shelf is touching the side of the cavity, an oven shelf support has broken, microwave waveguide, or bad magnetron.
If your microwave has a shelf in it, and you do not use it, keep it out. If one of the shelf supports breaks or comes out, the microwave will arc where the support was. You will have to sand the spot down, paint with appliance paint and re-install support. If the shelf shifts on the support and touches the side it will arc.
Your magnetron waveguide will either come out of the top, or side of the oven cavity. Some will have a stirrer in it(mostly top waveguides) with a panel over, or just a cardboard type cover over it. Over time, the stirrer cover can become warped from the heat which will expose the stirrer's metal shaft which will then cause sparking. These covers and stirrers come in a kit and can be replaced from inside the oven cavity.
Your cover over a side waveguide is coated with a substance on it, and overtime this coating can come off from the heat and moisture in the microwave. These waveguide covers are very easy to replace from inside the oven cavity. Touch up any paint that may have chipped or come off because of the arcing.
If your waveguide cover and/or stirrer are all OK, then the spark is coming from your magnetron. The antenna on your magnetrom has overheated and burned, sending the microwaves out at the wrong angle. If you catch this microwave oven repair early enough, you can usually get by with just replacing the magnetron. If the arcing has caused servere damage inside the waveguide, you will need a new microwave. Waveguides are not replaceable and most you can barely see into them, let alone sand and re-paint. In this case of microwave oven repair, when you remove the magnetron, you will see the burned antenna, or your magnetron will fail the test below.

WHEN IN USE IT MAKES A BUZZING SOUND FOR APPROX. 2-3 SEC. WE SEE A ROUND SPOT WHERE THE PAINT HAS BROWNED ON THE RIGHT WALL ON THE INSIDE OF THE MICROWAVE.


Hopefully this is just some grease on the waveguide cover / stirrer cover or the cavity wall.

If it's progressed to waveguide or magnetron damage, that gets expensive.

The first step is to inspect and clean these areas and replace the cover if it is damaged.

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

If the cavity metal is chipped or discolored, the area will first have to be sanded smooth and cleaned 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 / stirrer cover is burned, it will need to be replaced.

It provides critical protection for the magnetron.

The oven occasionally burns the bottom of food--it happens early in the baking process--what am I doing wrong? Cheryl


Make sure that the dishes you are baking in are approved for microwave use. Try running the oven at lower power if it is adjustable on this machine. It's possible that the 'stirrer' ( a fan like device) in the microwave waveguide (sheet metal tube between the magnetron and the cooking cavity) is not spinning for some reason. The cooling air from the magnetron flows through the waveguide and is supposed to spin the stirrer. Probably best to contact an appliance servicer to check this. Hope this helps!

Not heating. where is fuse?


Remove the outer cover. If the fuse is blown, there is usually a reason--a shorted high voltage diode and/or a shorted 'stirrer' bearing, which is a fan-like device near the area where the microwaves enter the cooking cavity and under the sheet-metal waveguide from the magnetron. Replacing just the fuse usually results in another blown fuse.

I have a Maytag model MMV5156AAB


Okay, that loud humming sound you are hearing is coming from the unit trying to energize the magnetron. Depending on how old your oven is, it could be still under warranty (this is covered under the warranty, trust me). If it is an older oven, like 2 years or more, you can bring it to an appliance repair facility and instruct them to replace the magnetron.

I am telling you to take it to a facility because you as a consumer cannot buy a magnetron...the federal government will not allow appliance companies to sell them to you.

My Advantium works sometimes. Other times it "pops and crackles" and the light flashes on and off...of course doesn't heat during those times.


holy **** clean that thing, its probly aluminum residue. watch out a leaking microwave can / will kill you hopefully the seals are ok.

dont even microwave items that were wrapped in aluminum foil just the residue can cause this.

have you ever microwaved a cd? take one and try it polishes them nicely.

Neff microwave h7871 arcing


This antenna is called the stirrer here in the US. Its purpose is to stir the microwaves to ensure even cooking.

The cover is usually made of plastic, as opposed to ceramic, and it keeps grease and food particles off the stirrer to protect it from arcing, which can damage the surfaces and the magnetron.

The stirrer, stirrer cover and the area around 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 in appliance parts stores and hardware stores.

Also, the stirrer will arc if it is not turning when the oven is cooking. That may mean a bad stirrer motor.

If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron and stirrer.

You can download Neff manuals here.

Even if you don't find your exact model, they should all have contact info for Neff in case you need to call them to get spares / parts.
