Do you have a Zanussi freezer that is not freezing and you are wondering how to fix it? You have come to the right place.
Zanussi Freezer Not Freezing – What to Do
There are a few factors that contribute to making a freezer stop freezing. One of them is the frequency at which the door of the freezer is opened. If the door is opened too often, the freezing capacity of the freezer is greatly reduced.
There is also the length of time the door is left standing open. This is a common occurrence, as people stand and decide what they want to take from the freezer. As simple as it sounds, it affects how well the freezer freezes.
Another factor is the door seal. A poorly sealing freezer cannot freeze as well as a freezer with a good door seal can. So check the seal to be sure it is still sealing well.
Additionally, the temperature setting of the freezer affects its freezing ability. Check to see if the setting is correct. You can always adjust it to suit the weather.
To add to the above, check the location of the freezer. Hot weather or any heat source close to it can reduce the freezing capacity. Relocate the freezer, if there is a need for it, to a room with a more ambient temperature.
Finally, check the power supply to the freezer and the power cord. A drop in voltage will make the freezer run intermittently. And if the power cord is damaged or is only partially plugged in, the freezer won’t run smoothly.
If all of the above is in place, then check the following parts to see if any of them is faulty if your Zanussi freezer is still not freezing:
1. Evaporator Fan Motor
The motor of the evaporator fan does not run when the door of the freezer is open. But pressing the door switch to activate gets the motor running again even if the door is still open.
So to test the motor, open the door of the freezer and press the door switch to activate it. If the motor does not start running again, then it is faulty and should be replaced.
If the motor of the fan is not in proper working order, the fan won’t be able to circulate the cold air in the freezer. Because of this, the freezer won’t cool or freeze.
2. Temperature Control Thermostat
Move the thermostat from the lowest point to the highest point and listen for an audible click. If you hear the click, the thermostat is likely working fine.
But if you don’t hear the click, then it is time to test it with a multimeter. If there is no continuity when you test it with a multimeter, the thermostat is faulty and must be replaced.
The thermostat moves the right amount of voltage in the direction of the two fan motors and the compressor. If it is faulty, then the motors and the compressor can’t run and the refrigerant won’t get power. As a result, the freezer won’t cool or freeze.
3. Condenser Coils
Check the unit to find the location of the coils. Some have them in the walls of the freezer, some have them under the unit while others have them at the back of the unit.
If the coils of your Zanussi freezer are visible at the back or under the unit, clean then with a soft brush. If you can easily reach them, use a rag to wipe them thoroughly and remove grease if there is any.
Dirty condenser coils cannot dissipate heat from the freezer. If the freezer carries heat continuously, it will be difficult for it to cool or freeze. So clean the coils every 6 or 12 months to leave them able to effectively dissipate heat.
4. Condenser Fan Motor
Spin the blades of the fan with your hand to check if they spin well. If they don’t, it is an indication that the bearings of the motor are worn out and the motor should be replaced.
However, if the blades spin well and are not inhibited by pet hair or any such debris from spinning, then test the motor using a multimeter to check for continuity. If there is no continuity, replace the condenser fan motor.
The condenser fan takes air through the condenser and passes the same air over the coils. If the motor is not working, the fan cannot operate. Consequently, the unit is likely not to cool.

5. Start Relay
Detach the start relay from where it is attached to the compressor. Place a multimeter between the start and run terminals and test for continuity. If there is none, the relay is bad and should be replaced.
Also, when you detach the relay, shake it. If there is a rattle coming from it, something is broken inside so the relay should be replaced.
Additionally, if the relay smells as if it is burnt, then be aware that it is damaged and should be replaced.
The start relay is responsible for supplying power to the compressor to enable it to start and run. If the relay is defective or damaged, then the compressor won’t get the needed power to run. Consequently, the compressor won’t run smoothly and this affects the ability of the freezer to freeze.
6. Evaporator Coils
If your Zanussi freezer is not freezing, inspect the coils behind the inside back panel of the freezer to see if they are frozen. If they are, you can thaw them by manually defrosting the freezer. This means that all the ice in the freezer will melt so store food items in another freezer or in a well-insulated cooler.
However, since it is an anomaly for the evaporator coils to be frozen, then it means that something is wrong with the defrost system of the freezer. One or more of the components is defective.
Test the defrost heater with a multimeter to check for continuity. It is usually found around the coils. If there is no continuity, replace the defrost heater.
For the defrost timer, rotate it counterclockwise with a flathead screwdriver until the defrost heater kicks into action. If this happens, then the timer is the problem and should be replaced. Consult your owner’s manual to find the location of the defrost timer.
You can also test the defrost thermostat and the defrost control board. If any of them is damaged, the heater won’t be able to melt ice off the evaporator coils, leading to accumulation of ice.
You can also check the user control and display board or the compressor if none of the parts above is defective. There is also the compressor to check for faults. Hardly do these parts become faulty but if they do, it can cause the freezer to stop freezing.
Additionally, check the freezer’s sealed system. A leak can cause a part of the freezer to stop freezing or even a portion of the evaporator coils to become frozen. If a refrigerator technician finds that there is a leak, the likely solution that is cost-effective is to replace the freezer. However, let the professional advise you.
It is important to contact the customer service center of Zanussi if the troubleshooting or repair is proving too difficult. There is also the option of our refrigerator technicians. Chat with any of them as they are always available to assist you.
