Question about Kenmore Microwave Ovens
This morning I was about to warm my coffee. When I hit "start" there was a little flash and the clock display went blank. Then I reset the clock (it took) and put the coffee in. The internal light came on and the turntable was spinning but there was no heat. Is this an easy problem to repair? It is a Kenmore Model 721.63252300 and is only 3 years old.
With the symptoms you
have, I would most strongly suspect a blown high voltage rectifier
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.
You can usually find helpful exploded view diagrams and order parts by entering your full model number at the Sears parts site.
Here are some links you or someone you know can use for test help, but read their safety warnings first:
