5 Simple Checks for Freezer not Freezing

Having your kitchen freezer break down can be expensive both with regard to the frozen food that spoils and the cost of having your freezer repaired.

If your freezer suddenly stops working or becomes ineffective, perform the following quick checks:

  1. Check for excessive ice in the freezer: Excessive ice in the freezer prevents the cold air from circulating. If you see an unusual build up of ice in the freezer, defrost the freezer completely. Now plug in the freezer to check if it is working as before.Remember, this may only be a temporary solution. As a normal process, self-defrost freezers turn off the compressor for a few minutes every 6-12 hours. Repeated excessive build up of frost in the freezer means that the freezer’s auto-defrost system is not working. Therefore, either the defrost heater, the defrost thermostat, or the defrost timer have a fault. This needs the attention of a professional appliance repair person.
  2. Check the thermostat: Perhaps the thermostat is stuck. Try turning it up and down again, and see if it clicks when you turn it. Set the temperature at the level recommended in the appliance manual and use a fridge thermometer to check if the problem has been resolved. If not, then you may have to replace the freezer thermostat.
  3. Check if something is blocking the freezer fan: Excess loading of the freezer renders the cooling system ineffective. Remove any food items that may have been stacked against the freezer fans. Also, if you cannot hear the fan operating when you open and close the doors, then you need to call a technician.
  4. Check the freezer door seals: If you see that the freezer door is not closing completely, check for damage of the freezer door seals. Sometimes simply cleaning the freezer door for any debris that may have accumulated can solve the problem. In case the freezer door gasket is damaged, it would need to be replaced by an appliance professional.
  5. Check the coils: All freezers have coils. These coils contain the refrigerant that absorbs the heat inside the freezer. If there is dust on the coils, the cooling function of the coils is affected. Unplug the fridge and very gently clean the coils with a vacuum cleaner or a dust magnets. If you are not sure how to do this, call a repair person.Your freezer may also not freeze for the following reasons:
    • There is a gas leakage, or a blockage that is restricting the gas flow in the fridge freezer
    • A noisy compressor indicates damage to the compressor motor. This part can be expensive to replace. Depending on how old your freezer is, it may be a wise decision to buy a new freezer.

Please remember:

Appliances should be serviced regularly according to the manufacturer’s instructions – found in the product manual. If you have a problem with an appliance, call in a NICEIC or Gas-Safe registered appliance engineer to repair your appliance. Don’t forget that if your appliance is not working optimally, you should also have it serviced to prevent causing damage to the appliance.
