Brian for Model Number RS2556SH I am having the seemingly common issue of the freezer working perfectly, while the fridge frosts over and warms to the high 50s-low 60s. I removed the back panel to find the water line and evaporator coils both frosted over. The error code given via the self diagnostic is the cool select zone sensor. I am not sure what that entails other than testing the Main PCB. I bought the entire evaporator assembly which includes the defrost heater and the temp sensor thinking they were obviously at fault as the defroster failed to work. I figured I would take off the defrost heater and reassemble onto the existing evaporator assembly in order to save on the bump in costs that a simple swap would incur. My confidence was shaken however, while defrosting the evaporator assembly I checked the continuity and found everything on the evaporator assembly to be good. Everything checks out the same installed as the new one does from the box. Does this mean I need a new circuit card or what? I don't know much about those which is why I am blaming it for now instead of ripping out my hair. Thanks in advance for any help you can offer.
Answer Hello Brian. Yes, if the evaporator assembly is testing good, but the board is not powering the heater, you will need to replace the control board DA41-00134F on the unit. Hope this helps. Read More... Answered by AppliancePartsPros.com | Friday, February 10, 2012
