Refrigerator is too warm. The top is warmer (60 degrees) than bottom (50%). Freezer is working fine. Slight frost on evaporator coils. Have replaced Adaptive Defrost control board. It has the ability to show fault codes. It seems to think that everything is operating properly. Manually put it in defrost mode and there were no fault codes showing, the documentation with the ADC stated that it would show a code once in defrost if the thermostat or heater were faulty. Seems to be no air flow from the freezer to the top of the refrigerator, if you open the freezer door, air begins to flow into the top. Compressor seems to be working. Fans seem to be working. Running out of ideas. Help would be appreciated, thanks.
ANSWER Hello Cindy. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
