“If the refrigerator is not cold enough the condenser coils may be dirty. The condenser is like a radiator and must stay clean in order to dissipate the heat which was removed from the inside of the refrigerator.

If the coils are dirty enough, the unit will never be cold enough and will not be able to cool the inside of the refrigerator to the proper temperature.” -RepairClinic.com – Read More Appliance Repair Tips About This Subject Here
