It is possible that your magnetron is heating up some soft spots inside the oven or there is a damage to the feed wires to the maggnetron or to the main capacitors. But before we start, I want you to be very careful. Remove the power and use a good flash light to look inside for the mountings near the magnetron-- a square/round fitting top right side of the oven when viewing from the front. If there is any possibility that your have not used food covers, some food could have splurted on to this and made it soft due to heating on the food. If so, you will have make a clean dry wipe, let it dry for some time before you test. If fault stays visualise the spot of smoke and invetigate . If you are powering the set with the cover removed please be very careful. replace the capacitor, wires or any insects/ cockroaches that have got entanged. hope you find this advise helpful Good day

I have a emerson mw8999rd that started crackling and sparking what cause this and can it be repair?

Sounds bad. Most likley caused by the magnetron tube arcing to the waveguide. Repair may be possible, but would be expensive (more than the microwave is worth). And if the arcing was severe or occurred for more that just 2 or 3 seconds, the waveguide may be damaged, and that is unrepairable.

If you need further help, reach me via phone at

The magnetron has failed and is the heart of the microwave oven, unless this is a warranty situation, go out and buy a new one cheaper in the long run.

Everytime i turn it on sparks fly

If they is any exposed metal in the cooking bay of the oven or grease it will cause it to spark and catch fire. If it is please clean the oven throughly. If it is sparking from the back the magnetron is bad and need to be replaced.

Where can i take a 'sparking' 900 watt emerson microwave oven in LA three months old? it also is smoking. 310.766-7500 david

Contact Emerson. Call the number on the back. More than likely they will tell you there is no servicer in your area and ask you to cut the cord and mail it back to them and they will send you a new one. I don't know if they'll do this for out-of-warranty microwaves as well.
