Good question meowzer. Also did it stop working just after you cleaned it or is this a question of its been in there 6 months and poof it just stopped? Have you tested the electrical outlet to make sure thats not the issue? Fuze box outside? Just some dumb questions but hey sometimes the most simple answer is the correct one. I almost replaced my garbage disposal because it quit working. My dad said "son, does it have a reset switch on the bottom of it and have you tried to reset it if it does?. Well you know the answer to that one!
