We just went out to the Copper basin community in San Tan Valley to check on a Samsung refrigerator that was not defrosting properly. When we arrived we found a lot of frost buildup on the evaporator coil, this happens when something within the defrost system fails and can no longer melt the frost on the evaporator. We tested for voltage from the control board down to the defrost bimetal as well as the defrost heater voltage was present so we checked the bimetal for continuity the bimetal had failed so we replaced it, problem solved. If your refrigerator is having similar problems please give us a call at 602-412-3133.
