New ice maker not working

[SIZE=3]The old ice maker was making a terrible noise but still makng a limited number of ice cubes. However I decided to replace it . New one arrived I install it and it does nothing after 24hrs. The electric connection slipped right together. However it does not even fill ice trays with water. Repleced the new ice maker with the old one and it started to make ice cubes again? I check to see if I had correct ice maker and I verified it with ApplianceParts Pro, it is the correct maker. I then contacted one of the advise forums and they said that it would starting working after 24hrs. After 24 hours still no ice?? Suggestions?[/SIZE]
