Multiple unsuccessful repairs

We bought GE profiel Artica form East Coast Appliances about 4 1/2 years ago. We has so far 6-8 repairs on the refrigerator. Fortunately I had bought extended warranty. It makes very loud noises and ice accumultas in the refrigerator section. They had so far put several heat pumps and changed even the circuit board so far. They have not fixed the problem and each repair would last only few months. We contacted GE and they don’t want to take resposnsibility for this faulty product. Any suggestions? Are there other customers who had similar problems?
