Kitchenaid KHMS155LSS 1000 watt microwave makes grinding noise

My Kitchenaid KHMS155LSS 1000 watt microwave oven makes a loud grinding noise in the top of the unit when operating. Most of the time, the microwave sucessfully heats the item. Occasionally, it does not. Any idea of what is causing the problem?

Chances are you have a bad stirrer motor or the stirrer blade is jamming or loose on the motor shaft.

Your owner's manual should tell you how to remove the stirrer cover to check it.

If for some reason you don't have your owner's manual, you can download it free here, as well as the parts manual for your model.

My kitchen aid microwave makes a loud crackling noise every once in awhild


Is it a carousel (turning platter)? if it is, than it is probably dirt on the platter support wheels and the platter support groove/track on the bottom of the oven, clean the glass plate, the support wheels, and the bottom groove as well, if you want to make sure the crackling comes from the carousel system, take it all out (support and platter) than place a glass of water in the oven and start it, if there are no crackling noise than my theory is correct, if the noise is still there than have it checked by a professional technician...

Rattling, crackling type noise just started and is constant when microwave is running.


A couple of months ago my microwave started making crackling, rattling and grinding sounds everytime i used it and i thought it was going to break down. It turned out one of my children must have spillled or overflowed something with a clear liquid because the micro did not look dirty but there was a crunchy substance under the wheels of the turntable. Once i cleaned this up totally the noises all went away.

How old is your microwave?
Would not be surprised if it is just the old magnetron; in which case it is easier to buy a new one...

Microwave makes a very loud sound when on like it is going to blow up. What could be causing this? It is a kitchenaid built in.


This is usually a symptom of a magnetron that is failing. I would recommend stop using it. A replacement magnetron costs about $163 at searspartsdirect.com. The part number is 8205791. This was the cheapest web source I could find it.
