Side by side refrigerator keeps freezing in the refrigerator side. I changed the board because the customer reported that the compressor runs "almost" constantly. I suspected a frozen relay. That didn't help. I changed the thermistors in both the refrigerator and the freezer on the coils. It's still freezng water in the refrigerator. There is no damper adjustment or damper motor in this model. The refrigerator thermistor is located in the rear left corner near the top.
