Question about Microwave Ovens

1 Answer

Sparks and flames

This was bought in 2001 and has had only 2 call-outs. It started to create sparks occasionally for no apparent reason so we solved this temporarily by placing a dinner plate on the turntable. The part inside the machine which looks like a piece of card is now creating fire when microwave is selected. The rest of the machine's functions are fine.
Can you tell me what part that is and if replacement of it will solve the problem please?

Re: Sparks and flames

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 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 smmoth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned (and it sounds like it is) it will need to be replaced.

I might be able to point you to a specific part supplier if you give me your brand and model.

I have an LG solardom microwave and when I want to heat a small amount of liquid, it sparks and the base(not the turntable) of the microwave gets hot.

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.

Whirlpool Oven Model GS563LXSS and Serial # RT2415211 turns it self off occasionally.

It is possible that the unit takes in too much current to cut off the controller unit so if there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now keeping clear switch on , use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues , you can use the microwave safely

I have a whirlpool microwave oven MH 7130XEZ-1. When I turn on the power, the shelf support sparks and flames. Do I need to but a new machine?

you need to remove the shelf support. If you can see bare metal in the oven. You need to get a bottle of white appliance touch up paint and paint over the bare metal. This sould solve the problem.

Microwave pops and sparks when running. Nothing

in the top of unit is a round cover and damage is coming from here. This is serious and needs to be checked out. the cover contains a stirrer that moves waves around<<circulates them>> in this cavity probably paint is thin and allowing waves to penetrate metal of cabinet. Call manufacturer and see if there is anything they will do for you before taking it upon yourself to either get repairman or get rid of unit.stirrer is probably damaged and cabinet burned from waves.

Emerson model MW8997w sparks when turned.

I bought a piece of mica from an appliance repair business and cut out a new piece. Microwave is working fine. Apparently food carbonizes on the mica and causes the microwave to spark. If anyone has this problem, call around and find a repair shop that buys mica by the sheet, rather than paying for a piece from the manufacturer.

Micowave sparks a fire

I had the same exact problem. My clips arced when I ran the unit and I also observed flames which was quite unsetteling. A work around for me, since I don't use the rack was I took it out then removed the clips. All that was required to remove the clips was a pair of plyers grabing each cliip at their base. I pulled firmly and there is alittle resistance but with a firm pull straight out they'll pop out.

But I have to say if you use rack your probably looking for a new mircowave.
