While I dont have that make/model, I had similar experiences with my kegerator when I first got it...Start by checking the temps at various places inside the kegerator. In my case I had a good 5 - 10 degree difference between the bottom of the kegerator and the top. I placed a small computer fan inside to circulate the air better. Once the temps evened out and stabilized, it worked soo much better. You can also consider increasing the length of the beer line but try the fan first.
