Refrigerator is assembled by different parts. These accessories work together and they need each other for effective operation. In case one of its parts has a defect or a default, it will affect the proper functioning of the refrigerator. That is why we emphasis if you notice an abnormal behavior with your refrigerator, make arrangements with a qualified technician to have it checked in order to prevent further problems like not freezing ice.
One of the problems that face the refrigerators is freezer not freezing the ice properly. The listed below are some research done trying to highlight some of the common reasons that may lead or cause the refrigerator not freezing ice properly.
Dirty condenser coils
Some of the refrigerators have their coils located within the walls of the freezer. These coils do not require cleaning. However if the refrigerator has its coils located in a place where they can be accessed from behind, then these coils requires to be cleaned every 6-12 months. If these condenser coils are left dirty they will not be able to disperse heat efficiently. This will automatically reduce the cooling capacity of the freezer. The solution to this problem is keeping the condenser coils all the time.
Evaporator fan motor
The air that normally circulates throughout the freezer is usually drawn by the evaporator fan motor over the evaporator coils. In case the evaporator fan fails and stops functioning, it’s impossible for the freezer to cool. Most refrigerators, the fan tends not to run or function when the door is open. Once it’s closed the fan motor begins to run.When you need to check the evaporator fan motor, just open the freezer door and manually activate the o door switch. If at all the freezer door switch is already activated and the evaporator fun motor isn’t running then the only option you have is to replace the evaporator fan motor.
The start relay
The start relay is very crucial since its major function is to provide power to the compressor. In case the start relay is not functioning well, or it is unreliable, it will lead the compressor from running intermittently or even end up switching off completely. If the compressor stops to function, then the freezer will not cool.It’s important to check if the start relay is defective. To carry out this process, you need to unplug the freezer and remove the start relay from the compressor. By use of a multimeter, test the start relay for continuity between the run and the terminals. Carrying out this process will help you rule out whether the start relay is spoilt. In case the start relay doesn’t sense continuity or rather smells burnt, you will have no other option except replacement.
Frosted evaporator coils
The most common problem behind refrigerator not freezing ice properly is the evaporator coils getting frosted over. This problem is usually in the defrost system. In this case you will discover that the defrost heater keeps turning on more often during the day. This is basically to melt off any frost that may have built up on the freezer evaporator coils.If the defrost heater is default and fails to turn on, this means the frost will continue to amass on the evaporator coils leading to the coils frosting over. To confirm if the defrost heater is spoilt; you need to test and confirm the continuity. In case the continuity isn’t there, replacement is paramount.
Condenser fan motor
The condenser fan motor basically draws air thought the condenser and over the condenser coils too. In case the condenser fan motor is not working properly, then it will be impossible to draw the air through the condenser. This will obviously lead to the refrigerator not cooling properly. If the fan motor isn’t running well, check the blades if at all there could be an obstruction. Always make sure that the blades spin properly and in case they aren’t spinning properly, then the fan motor bearings must be worn out. The remedy to this is just replacement. If all the factors are well, test the fan motor for continuity.
Temperature control thermostat
The function of the thermostat control is to direct voltage to the compressor, condenser fan motor and the evaporator fan motor. In case the thermostat fails, the refrigerant system will lack power causing the freezer not to cool. To confirm the thermostat is not effective, rotate the thermostat from the lowest setting all to the highest setting and listen for a click. The sound of the click will confirm that the thermostat is good. If you miss the click then check for continuity.
User control and display board
This part might be defective though it is at a very rare case, if it’s not functioning well. If you find out it has a problem the best remedy for this is replacement.
The compressor is a very crucial part of the refrigerator. If it’s not functioning well, then the freezer will not cool. Before replacing the compressor you need to check all the other parts if there is a defect. After ruling out that all the other parts are in order, you can now check the compressor. Check on the electrical pins if there is an open circuit and tighten it. Replacement of the compressor and any other checks must be done by a qualified and competent technician since compressor is very delicate.
Sealed system leak
If the refrigerator freezes the top shelf then there is a possibility of a sealed system leak most likely in one of the shelf. To repair a sealed system is very costly, so in case of the sealed system leak, you will be required to replace the freezer.
Main control board
The boards are mostly diagnosed wrongly. Before you rush to replacing the main board, it’s good to confirm with all the other parts to ensure there is no defective. After confirmation that all the other parts are good, then move to replace the main control board.
