Question about GE XL1800 1100 Watts Microwave Oven
Sharp model r-1461-a, serial 121279 made a loud humming sound and quit working. All lights and functions are now dead.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
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.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
http://www.gallawa.com/microtech/diode.html (if it is NOT shorted, it's probably fine)
You can usually find exploded views Sears parts site.
BUT Once you have the part numbers, the best place to order Sharp parts is Tritronics.
