We shut it down and then tryed to use it again. Sound good, all appears to be worlking fine but now will not heat. I have checked with GE & they said no recalls. Something is weird.

Re: Sparking ? Power Surge ?

I had the same problem. I replaced the wave guide/cover and everything was fine. It is a piece of cardboard inside the microwave that covers the magnetron. Mine was saturated with grease, and was damaged by the fire. If yours is still intact and not that greasy, You can carefully remove it. Clean both it and the area inside the cavity with an alcohol based cleaner. If there is so much as a pin hole in the cover it will need to be replaced. When grease somehow gets behind the cover an arc is formed which causes the problem.

My ge spacemaker xl1800 light and fan turn on when door is opened. small piece of foil does not spark during this. is there an easy fix?

Kent, most microwaves will turn on the light when you open the door. As for the fan coming on, does it do that all of the time or only after you have used it for a period of time? If it does only after you have used it, you might want to check the back and the underneath of your microwave to see where the fan draws air into the unit and clean any lint built up on the vent holes. Hope this helps!

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.

It sounds like your magnetron has failed.

I would put a cup or so of water in it and heat it for about 3 minutes.

Then check inside and see if you smell any electrical burning or other smell.

You should have a 5-year warranty on the magnetron.
