      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

Kenmore Microwave 721.66339011 burn smell

Recommended Posts

I have a Kenmore Microwave model: 721.66339011.  It has started to put out an "electrical burn" smell when running.   It appears to run fine still, heats, and works correctly.  I have the top off and can run it.  I can't see an smoke or isolate any particular part that seems to be the source of the smell.  How do I troubleshoot this?  Thanks for any help.

does it have a sweet order to the smell?

if do the high voltage transformer is failing

check the door switches for burnt/ heated push on connectors

they will also melt were the lugs go into the switch body

also the filter board with the main fuse on it can have

loose connections on the bottom of the board

this is an unit made by lg for sears

Thanks Leamy.

Not sure its a sweet odor, my son said yes, my wife said no, and I can't decide..  door switches are fine and all connections seems solid.  close sniffing while running it seems to be coming from the mag although that is right above the transformer and the fan is blowing over both.  Could not see any smoke and it works fine.  Anything I can check to voltage wise?  Thanks for your help.

Any suggestions that don't include paying $60 for a DVD set or $90 for a complete service repair book?  This microwave isn't worth that much. 

Thanks, Ray.

If you'll go to the link I sent you above and go down the left side you'll find all the trouble shooting info you need. You don't have to pay a thing. Just do some reading and look at some pictures.

Well, it looks like the transformer.  After looking at the price and everything my wife decided she wanted a new one.  Thanks to all for your help.
