Re: Microwave Not heating Foodas quick

You can find parts lists and diagrams on this Sears Web Page. There is a good possibility that your magnetron tube is getting weak. Make sure the interior is clean and doesn't have any rust or holes in it. Also check the seal around the door for corrosion. If you're not familiar with electrical and electronic repair work, you may need to take it to an experienced microwave service technician to get an accurate diagnosis of all the needed parts.

Kenmore Microwave Oven model #401.80082700

Sounds like a bearing is tightening up when it get heated up with use. Then after a cool down period it works normally until using it heats it up again. Eric

Kenmore Elite taking long time to heat items

This is most likely a failing magnetron.

If it's less than 5 years old, Sears/Kenmore should cover the part, but you would still have to pay for a service call.

If you or someone you know decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa:
