I am very frustrated! This is not a cheap fridge! We recently changed our water filter, even though the red light has never come on showing us it is time to change it! Now, we only get water to come out of the dispenser periodically. i hear the motor humming and then after a while it will come out. The main compartment does not hold the temp. and food freezes! I have lost so much food! It even freezes in the crisper drawers! We tried defrosting and checked the thermister , cleaned the coils etc. Our freezer is working fine since we replaced the Icemaker! Could it be the control board?

Please help!
