[I] have Frigidaire refrigerator model # fftr 2126LB top freezer just over a year old. It only cools to 50 degrees in the freezer and the refrigerator. Theirs no frost build up in the freezer[. The evaporater fan is running, the condenser coil fan is running, and the compressor is running. The copper tube exiting the compressor and going up to the evaporater coil is just slightly cool. Since this is a new refrigerator theirs very little dust has accumalated. Theirs no signs of oil on copper tubes or underneath as to a leak in the closed loop system. I checked the thermostat and it will turn the compressor on and off. Frigidaire web sight list no recalls for refrigerators. What's my move? ]
