Mine is in the cabinet next to the microwave, the cord forms a convenient loop that you can fit a fifth of your favorite booze in and it won't fall over. It also occasionally pulls the plug loose If that's not it check the breaker in the converter panel.

If it is like a household microwave, which it probably is, it's quite likely there is a internal fuse in the microwave. Test for power at the outlet, if you have power there, then problem is in the microwave. good luck.
