GE Refrigerator Top Not Working Freezer Bottom Is
I have a General Electric Refrigerator (Model No. GBS20KBPABB) with the Frige on the top, freezer on the bottom. About a week ago the refrigerator stopped working yet the freezer continues to work. a repairman came and checked it out (for $70) and said that the circuit board might not be working and he quoted me $211 to fix it with no gurentee that it would resolve the problem. After further investigation over the web we found that a thermomiter (a $9 part) could be the problem so we went ahead and purchased it. Now i have no idea where this goes or if it is even the problem. If anyone has any insight on how to install this part or if anyone has any knowledge of any similar problems please help me out.
p,s, After taking the top of the frige apart and found a damper on the top to let cold air in and I left the damper open to try to cool the frige but not enough cold air comes out of this damper regardless. help me please!
