Ice Maker not working properly!!!

I have a Kitchen aid side by side refridgerator and the ice maker makes ice every now and then. It drop a few ice cubes last weekend (after I got mad and pretty much shake the freezer a little) and then drop a few more cubes this weekend. So pretty much it drops a few cubes every 7 days.

Model no: KSRG25FSS05

Need to know if I should get a new ice maker or is there a way to fix it???.
