Hi, welcome to Eurobricks. 

Your post is a lacking a bit of info, but here are some troubleshooting tips:

Check the batteries in the remote and battery box, swap them out with new ones. Make sure the remote and receiver are set to the same channel (1 to 4).  Check both outputs on the receiver by connecting LED lights or motors to them. Connect different motors/lights to the receiver outputs to make sure you don't have a bad motor. Make sure your wire connection bricks are clicked in all the way.  Check that your battery box is putting out power by connecting the motor or lights directly to it. 

If this doesn't work you can contact Lego customer service, they will probably send you a new unit.
