Lonnie Barrios, the slight difference in tempature is within tolerance and probably fault lies with the thermometer and not the refrigerator. If you had a failed evap motor, your temp would be a lot warmer. When was the last time you cleaned your condenser coils? Dirty coils will cause a lot of problems. One common problem dirty condenser coils cause are clog in drain line. When drain is clogged it freezes and you’ll see frost/ice one the wall. The coils are near the compressor. Unplug refrigerator and carefully clean with a vacuum. Also clean the door gasket. If you see tears the gasket will need to be replaced. After you clean , spray a dry silicone and wipe into gaskets. This keeps gasket from drying and stiffening. Coils should be cleaned 1x a yr, more if you have pets.
