well i had the same problem there should be a reset button on the back and it would make the ac fan work but if you dont have the reset button, then the fan inside, is probably done. But if you can have someone take a look at it or even yourslef its could just be the belt inside has come off to make the fan work. i am not an expert but i do hope you can get it working.
P.S to take a look inside you have to unscrew the front off and you will soon tell whats wrong.
Again, I think you mean well but this is not good advice. Please - post in teens and children and don't answer what you don't know.
