I know, even a small kid knows that the freezer is supposed to be colder than the fridge; otherwise there is no point in calling it the freezer, is there? However, if the freezer is functioning properly and freezes the items you put in but the fridge is not cooling properly, then you have a problem.
Do not worry, it is generally not a huge problem that will cost you a lot of time and money and, if you are good with equipment and has proper knowledge, you may be able to solve the issue easily by yourself.
Few causes for the said condition are listed below so that you will be better prepared when you encounter this issue.
Too much stuff
You may have stuffed your freezer with too much goods and the air flow to the other areas is not happening as it should. If you are unsure whether this is causing the issue, take some of the things out and wait for a while to see if the situation improves.
Similarly you may have put too much things in the fridge and have set the cooling dial to a lower level. It is always better to check for these little things before you think of more complicated causes.
Malfunctioning parts including air circulation components
There are several components that assist in the air circulation and the proper cooling. The coils should most definitely be checked to confirm that they have not been frosted. If they are frosted you will want to check the defrost heater assembly to make sure that it is functioning properly as this is the main culprit in this kind of scenario.
Defrost timer malfunctioning may also cause similar symptoms and, therefore, it is a good idea to check it if you know what you are doing. However, if you are unsure about the functioning of the timer or how to check it, it is advisable to eliminate the other possible causes and then calling a professional repairman.You can try manually defrosting the cooling coils and allowing the refrigerator to function for some time to determine if the issue is really with the defrost heater assembly or if it is with the defrost timer. Failures of evaporator fans can also create the aforementioned issue. Click here for more info on cooling coils.
If the motor is unusually noisy or the blades do not freely rotate when you turn them by hand, you may have identified the root cause. In this event it is better to enlist professional help rather than trying to replace the fan by yourself.If the damper control assembly is broken or if it blocked the cooling will not happen as desired. Therefore, this is yet another component that should be checked if you are experiencing the weird but not so uncommon phenomenon of the cold freezer and hot fridge.
