The problem you are having is that the magnetron that does the heating is shorting out and it needs to be replaced before it damages the inside covering of the microwave. www.mwoparts.com is a good source for magnetrons or other similar sites. To replace is easy enough. Taking the cover off with the power off, you will find it behind and on the top right side of the control panel. It is held in place normally with just 4 screws and two wires with terminals attached to it. So removing and replacing is pretty straightforward. Just be sure all the power is off until you have everything back in place. Good luck.

GE Spacemaker XL1800 sparking from behind wave stirrer cover


Microwaves use a magnetron to generate microwave energy and direct it a rotating blade wheel to spread them around the inside of the oven. If there is any metal in the area to be heated, or any of the blades are bent, even a bit, the microwave energy can be reflected back up to the magnetron area. In this area there is now too much power and it sparks away, so it does not heat the item in the oven.
Because it is sparking it is now a safety hazard the sparks may melt and set fire to plastic parts in it. This is serious it could burn your house down. Bin this microwave and cut the cable off it to make sure no one else ever uses it.

A number of days ago we put two plates of food in the microwave to reheat them. There was a snap, crackle, pop noise. We checked to see there was no metal object in the unit....there wasn't ...we know...


Are you sure the plates were Microwave oven safe? Some dishes have metal in the colors of the design. A snap, crackle, pop noise normally means there is metal present in the oven.

Turned it on to heat food and make a loud noise , did not heat food and have electrical short ordor.


there is something metal inside that is causing this look for any screws or anything that may have been switch with a repair. what happens is the metal causes the microwaves to reflect back to the magnetron instead inside the food causing noises and sometimes sparks and odor. find the metal object remove it and this should solve your problem

No heating, turntable does not turn, but clock & lights work.


Check to make sure the plastic on the shelve holders or tuntable guide did not wear and expose metal. If these holders or brackets are wore and exposed metal it shorted out your micro wave. They need to be replaced and a fuse needs to be replaced inside the control panel,

Humming and sparking inside the microwave


Sounds like you have metal inside oven, and arching can happen if nothing is in there to absorb energy.

Crackling sound in microwave vent when power is off


By "powered off" can I assume you mean that it is plugged in and at idle, not cooking, just showing the clock?

If so, I'd say your control board is failing.

If my assumption is wrong, please write back with more details.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Crackling/sizzling sound


If you're hearing a crackling noise and don't see any sparks, you may have a magnetron that is arcing inside the waveguide. Once this arcing occurs, in some cases, replacing the magnetron may not be enough to fix the problem. There was also a noted problem with some models where the stirrer motor shaft inside the waveguide would arc when the magnetron was energized. This too, caused damage inside the waveguide. If the internal walls of the waveguide become damaged it cannot be repaired and the unit must be scrapped. The waveguide has a special coating to help propagate waves of RF energy. If the walls are damaged due to arcing this special coating gets burned off and will continue to arc even if a new magnetron is installed. This will eventually lead to magnetron failure and potentially cause a fire inside the oven. I would think seriously about looking into another unit if any of this may be occurring in your oven. Better to play it safe, especially with small children. I hope you find this advice helpful. PS A new magnetron can run as high as $250.
