GE fridge model TCS18PADBLBS bottom freezer. Problem is, food are getting frozen in the fridge and it seems never stop running. I did clean the grill and the coil from dust.fan is working fine. I am able to get to the temp control and the freezer frost control and when i turn the freezer control with screw driver, the fridge stops for about 20 minutes then kicks in again, despite that the fridge is still very cold . I turn the control all the way to off, but fridge keeps running. any idea what cause it. I can buy new controls but they cost about $170 and I hate buy them to find out if that wasn't the problem. thank you for any help![]()
