I have noticed that my refrigerator will run non-stop and the refrigerator has a hard time dropping the temperature below 45 degrees. The freezer has no problem cooling. I checked the condenser/condenser fan and it all seems to be working properly. What I have noticed is that the baffle/damper on the top left towards the back keeps opening and closing non-stop. This baffle restricts and also allows cool air from entering into the refrigerator side. I believe the constant non-stop opening and closing of this baffle is restricting cool air from entering the refrigerator. This makes the refrigerator run continuously since it never actually reaches temperature. What should I check or replace? Please help! Thanks!
