I am having a condensation issue with my GE side by side refrigerator PSS26SGPA. The area of the water/ice dispenser is constantly sweating to the point that I have a collection of water in the tray after a day or so. To date, I have replaced the recess crank and spring, flapper(twice) and solenoid. I've done everything that I can find scouring websites. The plastic behind and below the ice funnel is cold to the touch. Is there something I may have missed? Is there an "anti sweat" heater in the door? Any other heater circuit that may have failed? Is there something else I can try that may help me? I am not afraid to take it apart and test possible electronic issues.

Otherwise the fridge works fine. Thanks in advance for any advice.
