Birth defects or genetic disorders can also be caused by a problem with the number or structure of chromosomes. Usually this results in multiple body systems being affected. Approximately 1% of all babies will be born with chromosomal abnormality, which can cause physical problems and mental retardation. 2  More than 20% of infant deaths are caused by birth defects or genetic conditions (e.g. congenital heart defects, abnormalities of the nervous system, or chromosomal abnormalities).
We tend to put the fridge on at least 24 hours before departure. How quickly it gets cool can be influenced by the ambient temperature. Although it should cool down overnight. If you don't think its getting cold enough on mains it might be worth trying to cool it down initially on gas.
If this is a new unit: 1  Allow about 24 hours for the unit to cool down and stabilize after initial installation. 2  If 24 has passed and and the controls have been set properly but the unit is still warm, you may need to schedule service. 3  Schedule a service appointment on-line. This is because the items in the refrigerator absorb the cold, and actually work to help the refrigerator maintain a steady temperature, in much the same way that ice cubes keep a drink cold. 2  When you open the refrigerator door, the cool air rushes out and warm air rushes in.
