Marquesas II by hampton bay, won't work

I bought this ceiling fan light combo to update my living room existing fan light fixture. It is connected to light switches on both sides of the room, Since I was replacing an existing combo I connected exactly as the previous unit but can get no response from the fan or light, is there a way to tell if the problem is in my new product? I really don't want to to pay an electriction another 100 dollars only to find out the fan is no good.
