Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

In this model, it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.

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 smooth and clean 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 is burned, it will need to be replaced. It provides important protection for the magnetron.

While you have the cover off, look for grease buildup or charring on the metal and the stirrer (an antenna or blade-like device).

My space saver microwave will not heat anything yet everything else works.

i found on my micro setting if i accidentally set it up for convection, it stays that way and therefore just heats slowly when I think i'm microwaving. i have to re set it after i use convection or it defaults to that and therefore will not heat / microwave.

I have a space saver micowave. When I start it, it sounds like somthing is getting zapped. It also does not heat. It started with microwave popcorn and does it all the time and we cannot use it. Can you...

Hi Bob,
Chances are have either a bad magnetron tube or the filament transformer that is failing and arcing. The replacement cost of the parts & then labor to diagnose and install is probably more than it's worth so I would suggest you just consider buying another one. Also, Microwave Ovens radiate RF and unless you are trained in how to test for that and verify the shielding hasn't been compromised during repair, I wouldn't try to fix it myself. As an added concern, there is also High Voltage in there as well.. Your call.. but I would probably discard it and consider another one.. Hope that helps..

Oh.. for a quick test, remove everything from inside the cooking compartment and place a cup of water in there.. turn the microwave on for ~ 2 minutes..does the water get hot? boil or stay cold? If it stays cold.. discard it.. If it gets warm, the magnetron is probably in the midst of failing but if it gets hot .. then you may only have a loose connection in the electronics compartment ( magnetron, transformer etc) Something to hope for.. :-)
