Frigidaire Gallery Water Dispenser and Icer Problems

[SIZE=3]My Frigidaire Gallery FRS22XGCW3 side by side recently quit making ice. Previously, 1 yr ago, the ice maker inlet tube was frozen but I fixed that and it has worked just fine until now. The water dispenser has not worked for quite some time now but I just stopped using that. I have read to replace the filter but I cant locate a filter to replace. Water is flowing throught the copper tubing in the back. I have also poured water into my ice maker to try and jump start the cycle. The ice was dispensed but a new cycle was not started. At random intervals my ice machine decides to work because I will find ice cubes in the bucket but it wont fill it up.:confused: Please advise because it got over 100 today and I need some ice! I would also like to try and fix my dispenser as well. I took the refrigerator drawers out in search of a filter and found the water container and it was full.[/SIZE]
