Why does my refrigerator not cool?

A refrigerator not cool is one of the most common faults that is reported to us, there are many and varied reasons why a fridge will not cool but I will go through the most common causes.

Ice build up

Most modern fridges are frost free meaning that you do not need to defrost them manually. When something goes wrong ice builds up in the air ducts and evaporator stopping the cold air from flowing throughout your fridge.

Some of the reasons for the ice build up are

  • Faulty defrost component
  • Blocked drain
  • Door left open
  • Broken door seal
  • Faulty computer board

Often if you leave the fridge off for 24 hours with the doors open it will rectify the problem but in the cases where it is a faulty component it will only be a temporary fix and will revert back to the previous state.

Motor not running

If you cannot hear the compressor running the thermostat or computer board could be faulty.

Motor clicking every few minutes

This could possibly be a very serious problem, usually it is a sign that the motor is seized or a winding burnt out. If this is the case it is one of the most major faults a fridge can have and the repairs may exceed the value of the fridge.

Motor running but fridge and freezer warm

Often this is a sign that there is problem with the sealed system, in other words the pipework. There could be a blockage in the pipework or the refrigerator may have lost its refrigerant because of a rusted or broken pipe. This is another serious problem that may write off the fridge.

Fan in freezer not running

This fault only relates to frost free freezers. The fan pushes the cold air throughout the fridge and if the fan motor is not running the refrigerator cannot cool correctly.

Note –

These faults are only meant as a general guide and are not meant as a definitive answer as to how to fix the fridge or if the fridge is worth repair.
