Hey Everyone, Need a little help diagnosing my Samsung french door fridge/freezer. The freezer side seems to have a very hard time cooling down to the temperature I set it to. The fridge on the other hand is fine. All of the cooling/circulation fans work as they are supposed to. When I pulled the back panels off to expose the evaporator coils I noticed that the freezer side was frosted right up on the top of the coils but not so much on the bottom. IN my research it looks like that could be a restriction to the flow of refrigerant. Then I learned that there is a thing called a 3 way step motor valve. Which diverts the flow of refrigerant to either the fridge or freezer. and if that gets stuck on the freezer only cool mode, the fridge wont cool, if it gets stuck on both fridge freezer mode then it will still work.. just with more energy. What I believe is happening is that it is stuck on the fridge only cooling mode as the freezer seems to be getting very little flow of coolant. I found a tech trouble shooting tip here Samsung troubleshooting It super little information on troubleshooting the step motor valve other than to test the resistance between the common and the 4 phases of the motor, all of the phases should be 40 ohms + or - 10%. I have verified that the windings are all good. from what I can tell it seems as though the portion of the valve that actually move back and forth is stuck... it does not seem like there is a way to move it by hand? or how could i trick it to move? Does anyone know how to check the "signal" to the valve? All I see on the wire diagram is a 13v common and 4 phases... but that doesnt tell me which direction its moving, what setting its in etc... Sorry for the longggg right up. I would super appreciate any info anyone has on this topic
