Ice Maker stopped producing ice

I determined that the icemaker was not getting any water to the unit. The icemaker was still cycling but was not filling with water. I assumed the water valve was malfunctioning so I looked up the schematic drawing on the site and ordered the Water Valve & Bracket Assembly. It arrived within days. It took less than 10 minutes to install with miniumal effort. Within minutes the water could be heard flowing into the unit. Within an hour we had ice again!!!!!!!!!!!!!!!!!!!!!!!!
