Can't be bothered to write and punctuate a complete sentence, eh?  Here is the programming manual: https://www.dsvendinginc.com/images/pdf-manuals/nv30.pdf

First try page 46, then 45, then maybe page 16.  You could have bad motors, a bad shelf harness or a bad shelf interface board on the right side of the cabinet.  For quick testing you should swap the shelf with another and see if it works in the alternate position, also seeing if the working shelf still works in its alternate location.  This will isolate the issue to the shelf or something beyond the shelf.  Your real issue should go no further than the shelf board but it could go back to the snack interface board.
