Try plugging it into another outlet (test the outlet first with a blender?). You might want to check your circuit breaker (you may find that if you toggle some switches, one switch will actually take less effort to flip, this is because it is blown, but it doesn't set the switch to off when it blows. I have these types so it is really hard to tell if it's a circuit breaker just from looking at it). Trying other outlets is one one to check if it is a breaker issue. I had one outlet in my kitchen with burn marks, that didn't work but the plugin right below it worked fine.
