I have since replaced the defrost heater, temperature sensor, defrost limiter and control board. $200 spent and still no results. What else could it possibly be? The compressor is running or the coil wouldn't be frosted over. The temps are 8/45 (freezer/fridge). I can get the freezer colder but the fridge never does. The condenser fan is running and the coils are clean (I vacuum every few months). The evaporator fan is running.
