Defrosting is very important to maintain the cooling inside the refrigerator. If the defrosting fails, ice will build up on the evaporator coil due to which the food section and freezer will not stay cold enough.

During the
refrigeration cycle of a refrigerator, moisture in the air freezes and sticks
to the evaporator coils as frost The refrigerator has to go through a defrost
cycle to melt this ice that continues to build up on the evaporator coils from
the moisture in the air. If the refrigerator has a defrost problem the frost
collected on the coils will not melt. Sometime the frost builds up to the point
that it blocks airflow and the refrigerator stops cooling.
Refrigerator
defrost problem is difficult to fix and most of the time require a refrigerator
repair expert to identify the root of the problem.
Defective defrost system:
In any frost free fridge there is a defrost system which controls the cooling
and defrost cycle. The components of the defrost system are: a defrost timer
and a defrost heater:
So when either
of the 2 become faulty, the fridge does not understand when to cool and when to
defrost.
Defective thermostat: If
the refrigerator does not defrost, the defrost thermostat might be defective. In
a defrost system, the defrost heater turns on several times in a day to melt
away the frost developed on the evaporator coil. This defrost heater is
connected to a defrost thermostat. The defrost thermostat senses the
temperature of cooling coils. When the cooling coils become cold enough,
thermostat sends signal to defrost heater to turn on. If the thermostat is
defective it may not be able to sense the temperature of coils and then won't
turn on the defrost heater. If the defrost heater doesn't turn on, the
refrigerator will never start the defrost cycle and will eventually stop
cooling
The above are
some common reasons behind refrigerator not defrosting problem but there can be
other reasons as well.
