The ice maker wont make ice and the frig gets colder and turns everything frozen. Is this problem the board?
You will want to check the damper that is located behind the icemaker auger assembly which is most likely stuck open. To access you will take the ice bin out. On the left bottom part of the compartment there is a small hole, Put a small screwdriver in there at an angle and push the screwdriver up and slide the panel forward. Then you push the tab on the side of the icemaker and the assembly will come out. Once out check the damper that is located at the back of the assembly.
