Have you ever invited friends over for drinks and found the wine to be warm despite refrigerating it for hours? This could be so embarrassing! How about opening the refrigerator on a hot afternoon with the hope of sipping on chilled water? Imagine not having cold water in the fridge when you feel so parched. Nothing can replace a glass of chilled water in that state.
Beyond having the luxury, a refrigerator not cooling can be a serious concern. Your appliance will begin to have a foul smell due to the food being spoilt. The milk will turn sour. There will be high chances of discovering bacteria and mould growth in the refrigerator. These are potential health hazards and can result in serious problems. Therefore, there’s no way you can take this issue lightly.
Now, if your refrigerator is old enough (15 years or more), you will gradually find the efficiency dropping. Making an effort to repair it will be a waste of your time and money. So, leave that thought behind and bring yourself the best refrigerator.

However, if your appliance is fairly new, it’s best to diagnose the problem and get it fixed. So, what do you do when your refrigerator stops cooling? Know it all with me. Right here, right now!
Refrigerator not cooling? Reasons & Solutions
1. Overstocking the Refrigerator
Filling in the refrigerator or freezer with excessive food is one of the biggest mistakes. I have noticed most Indian households overstocking their refrigerators with weekly veggies or cooking excess food and then having an abundance of leftover food.
Guys, hold your horses! Do not overcook. Do not overbuy. Do not overstock. It will lead to less air circulation in the refrigerator. And then your appliance will struggle to cool. Therefore, overstocking is a big NO.
2. Not cleaning the refrigerator
The refrigerator is bound to have spills of food, milk, juices, and other things stocked in. While taking them in and out, you may end up have some spillovers. A minor leak in some packaged food can also be the reason behind your refrigerator having splatters. Well, these are all accidental, and they may not be in your control. But cleaning them right away is totally your call. Out of sheer laziness, people sometimes tend to leave the refrigerator and plan the cleaning later. But does that later ever come? Or do the stains dry up, and you stop noticing them? This gives space to contamination and bacteria in the refrigerator.
Consequently, it will result in diseases and deteriorate the efficiency of the appliance. You will notice the efficiency of the refrigerator diminishing by the day. So, do not encourage any bacteria growth in the appliance.
3. Faulty Door Gaskets
Every refrigerator door is equipped with a rubber gasket. This is a tiny little component but plays a pivotal role in the functioning of the appliance. It is capable of sealing all the cool air inside the refrigerator. In case of any fault or damage in the rubber gasket, the cold air will seep out easily. This will make the refrigerator incapable of maintaining the temperature. So, you will find inefficient cooling in the appliance. Therefore, keep a constant check on the rubber gaskets.
4. Dirty condenser coil
Condenser coils are placed at the back of the refrigerator. They are responsible for carrying the hot gas released by the compressor. The coils cool the refrigerant. If they are dirty or blocked, the refrigerant running through them will not lose the heat. This means the refrigerator won’t cool enough. A dirty condenser also causes the compressor to overheat. Once the compressor overheats, it will stop functioning. As a result, the refrigerator will stop functioning as well. And then, of course, there will be no scope of cooling.
Therefore, you must keep the condenser coils absolutely clean and in proper condition. No dirt, no spiderwebs, no grease! Even a dash of it can result in poor air circulation and make your refrigerator lose its cooling ability.
5. The evaporator fan has gone bad
The evaporator fan is the reason behind the cool air you feel every time you open the refrigerator door. It draws all the air across the evaporator coil, cools it completely and then moves it back to the refrigerator and the freezer. If there is any fault in the evaporator fan, there will be a rise in the freezer and refrigerator temperature. Once the evaporator fan stops completely, the refrigerant temperature will rise, and the compressor will overheat. When the compressor overheats, the unit will not produce any cool air and stop functioning eventually.
If you have any difficulty in the process, seeking professional help will be a good idea.
6. Inaccurate temperature control
Are you aware of what is the correct temperature for a fridge and freezer? The refrigerator temperature should be between 36 – 40 ° F, i.e. 4° C. the ideal freezer temperature should be 0° F, i.e. -18° C. You can decide on the exact temperature depending upon your model and the user manual.
If you have ever felt that the fridge is not cooling, but the light is on, a temperature check should be your first inspection. Most likely, you may have set the right temperature. But accidental bumps can be a reason behind any kind of unintentional change.
7. Blocked vents between the freezer and fridge
The vents between the freezer and fridge play a big role in keeping your appliance cool. If the vents get blocked by any food item or covered by ice, it will lead to moisture build-up, decreased airflow or inconsistent temperatures. All these issues will hinder your appliance’s functioning, and you find your refrigerator not cooling enough.
8. Refrigerant Leak
Here is another reason for your refrigerator not cooling enough. A refrigerant leak can happen if you have attempted any repairs and gone miserably wrong or if you have scrapped off the ice from the freezer. In any situation, this is bad news for your appliance. How do you know there is a refrigerant leak? You will find all the food losing its freshness, and it will feel warm no matter how many hours it has been. You will also begin to sense a musty smell from the refrigerator. Hence, it is not so difficult to detect this problem. A refrigerant leak will make the compressor work very hard. So, your appliance will begin to have cooling issues. You will also be in for some unreasonably high electricity bills. Are we ready for it? Certainly not!
9. Stuck air damper
An air damper circulates the flow of cool air between the refrigerator and the freezer. A stuck damper will restrict airflow, and you will notice your appliance functioning but not cooling enough. How do you diagnose this problem? Stick your hand ahead of the vent. Can you feel cool air? If you are certain about the evaporator coil functioning properly and the vents not being blocked, then a stuck air damper is the only reason behind inefficient cooling.
10. Compressor Failure
A compressor is an indispensable part of the refrigerator. It circulates the refrigerant throughout the system and pushes it into the coils. A compressor enables the whole cooling process. If you find your freezer fan working perfectly and the refrigerator not cooling, a bad compressor could be the culprit.
In this situation, there could be two potential reasons. One, there is a fault in the compressor start relay. Two, there is a fault in the compressor. Replacing the compressor start relay is a relatively inexpensive affair compared to replacing the compressor itself. So, try your hands on that first.
- Step 1: Unplug the refrigerator.
- Step 2: Move the appliance a bit away from the walls.
- Step 3: Remove the old compressor start relay (at the bottom of the refrigerator).
- Step 4: Buy a new start relay and test the existing compressor.
- Step 5: Give it few hours and check if the appliance is cooling the way it should.
Are you still facing the problem? In that case, the compressor needs a replacement for sure.
If installing a new refrigerator compressor procedure looks intimidating to you, expert help is a great option.
