I am the lucking owner of a ge profile bottom freezer refrigerator, bought in 2005. Every summer the temperature in the freezer warms up to 15-25degrees. In 2007, the refrigerator failed totally. A repair tech replaced the motherboard as has worked ok during the winter. However the summer months the refrig. runs constantly. The temp still runs warm in the freezer. I have looked at the compressor. The coils are clean, compressor is hot. No frost build up. The cooling fan is running, but seems at a very slow, lazy speed. Enough so I could stop it with my finger. Does the cooling fan normally run this slow. Or is this the nature of ge profile?
