Hello there,
When you are
experiencing ice build up in your refrigerator and a part of the refrigerator
is not getting cold, either the fridge or freezer compartment. Then it means
there is a problem with a part in the unit.
Investigate these
three areas if frost and ice are forming in your freezer and your fridge is not
cold enough, test Defrost Timer, Defrost Heater and the defrost thermostat when
you detect where the problem is from, replace it.
Before
you begin to test your defrost thermostat, defrost heater and defrost timer,
make sure you disconnect the appliance's power supply.
Here are some tips for you to go through in order to solve the problem.
