In less the 5 years we have replaced 3 of the plastic components used for storage in the refrigerator.  Last week the compressor stopped working so both refrigerator and freezer has stopped working.  Fortunately we were able to move all of our food down to a 15 year old Amana refrigerator that we keep in the basement.  The extended warranty that we purchased from the retailer did not cover any of the plastic components but fortunately it covered the compressor.  The refrigerator will have been down for nearly 2 1/2 weeks by the time the compressor is expected to arrive.
