A refrigerator is necessary to keep our food fresh and guard against spoilage. Opening your refrigerator only to discover that the temperature needs to be sufficiently high to keep your food fresh can be frustrating.
This may result in food waste, spoilage, and even health risks. Numerous factors could be at play if your refrigerator is not cooling correctly.
We’ll look at some typical reasons why a refrigerator won’t cool down in this blog post, along with some advice on how to fix the problem.
Understanding how to identify and repair a fridge that isn’t cooling can help you avoid wasting time, money, and aggravation, whether you own the home or are a renter.
Why Refrigerator Not Cooling – Common Causes
It can be annoying and worrying when your refrigerator isn’t cooling properly. It can cause food waste and spoilage and may indicate a more significant issue. Some typical reasons why a refrigerator may not be cooling include:
1. Dirty Condenser Coils:
Your refrigerator’s condenser coils are in charge of dissipating heat from the appliance. These coils may accumulate dust and debris over time, hindering their ability to perform as intended.
When this occurs, the refrigerator might not be able to cool properly. You can resolve this problem using a soft brush or vacuum cleaner to clean the condenser coils.
2. Faulty Evaporator Fan:
Your refrigerator’s evaporator fan moves cool air around the appliance. Uneven cooling or no cooling may result from this fan not functioning correctly. You can determine whether the evaporator fan is operating by opening the freezer and listening to the fan. You might need to replace it if it isn’t working.
3. Blocked Air Vents:
Cool air can circulate throughout your refrigerator thanks to air vents inside. The refrigerator’s cool air may not reach every area if these vents are clogged with food or other objects. Avoid overloading your refrigerator and ensure enough air circulation to clear these vents.
4. Faulty Thermostat:
Your refrigerator’s thermostat is in charge of controlling the temperature inside the appliance. If it isn’t functioning correctly, there may be temperature swings or no cooling. By adjusting the dial up and down to see if the temperature of the refrigerator changes, you can determine if the thermostat is operating properly. If not, you might need to have the thermostat replaced.
5. Low Refrigerant Levels:
Chemicals called refrigerants are used to cool the air inside refrigerators. The fridge may be unable to cool effectively if there is a leak or low refrigerant levels. Since this problem involves finding the leak and recharging the refrigerant, a professional must resolve it.
Why Refrigerator Not Cooling – Troubleshooting
Knowing where to begin troubleshooting a refrigerator that isn’t cooling can be difficult. Here are some suggestions to aid in problem diagnosis and resolution:
1. Check the Temperature Settings:
Inspect your refrigerator’s temperature settings to make sure they are correctly set. A refrigerator should be set between 35 and 38 degrees Fahrenheit (1.7 and 3.3 degrees Celsius). The refrigerator may be unable to cool correctly if the temperature is too high.
2. Clean the Coils:
As mentioned, dirty condenser coils can make your refrigerator unable to cool properly. To avoid this problem, make sure to clean them regularly.
3. Check the Evaporator Fan:
The refrigerator may be unable to circulate cool air if the evaporator fan is not operating. By opening the freezer and listening to it, see if the fan is running. You might need to replace it if it isn’t working.
4. Check the Door Seals:
Check to see if your refrigerator’s door seals are tight and damage-free. Warm air may enter the refrigerator if the seals are broken or loosened, preventing the refrigerator from cooling effectively.
5. Remove Any Blockages:
Inspect your refrigerator to ensure no obstructions in the air vents. Overcrowding your refrigerator can make it difficult for cool air to circulate, resulting in uneven cooling or no cooling.
6. Check the Thermostat:
As mentioned, a broken thermostat can prevent your refrigerator from cooling properly. Turn the dial up and down to see if there is any difference in the temperature of the fridge to see if the thermostat is operating correctly. You should have the thermostat changed if it doesn’t.
7. Defrost Your Fridge:
If you notice that ice has built up on the evaporator coils, it can prevent the fridge from cooling correctly. This problem may be resolved by defrosting your refrigerator.
How To Diagnose And Fix A Faulty Thermostat In Your Refrigerator?
Your refrigerator’s thermostat is in charge of controlling the temperature inside the appliance. If it isn’t functioning properly, there may be temperature swings or no cooling.
To identify and repair a refrigerator thermostat issue, follow these steps:
1. Check Power Supply:
Before starting any diagnosis, ensure that the refrigerator is getting power. Check if the power cord is plugged in correctly and if there is no damage to the cable.
2. Check Thermometer:
Use a thermometer to check the temperature inside the fridge. If the temperature is too high, it may be due to a faulty thermostat. If the temperature is below the recommended temperature range of 35-38°F (1.7-3.3°C), the thermostat may be stuck in the “on” position, leading to overcooling.
3. Inspect thermostat:
Inspect the thermostat for any signs of damage or wear. If the thermostat is damaged, it will need to be replaced. If there are no visible signs of damage, check the contacts for any signs of corrosion or debris. Clean the connections with a soft brush or cloth if they are dirty or corroded.
4. Test Thermostat:
To test the thermostat, turn the dial up and down and listen for a clicking sound. If you hear the clicking sound, the thermostat is working correctly. If there is no clicking sound, the thermostat may be faulty and needs to be replaced.
5. Replace thermostat:
It must be replaced if you have determined that the thermostat is faulty. To replace the thermostat, follow these steps:
- Turn off the power to the refrigerator.
- Remove the control panel or cover to access the thermostat.
- Disconnect the wires from the old thermostat.
- Remove the old thermostat and replace it with a new one.
- Reconnect the cables to the new thermostat.
- Reattach the control panel or cover.
- Check that the thermostat functions correctly by turning on the refrigerator’s electricity.
How to find your Refrigerator Needs Repair:
An expensive, long-lasting refrigerator is a good investment. However, issues that need expert repair commonly arise with them.
Here are some indicators that your refrigerator requires repair and when you should contact a technician:
1. Your Fridge Is Making Strange Noises:
Strange noises coming from your refrigerator, such as rattling, buzzing, or humming, are a warning that something might not be correct. While some noises are familiar, others, such as those from the motor, compressor, or fan, can be unusual and point to a problem. It’s best to call a specialist to diagnose the problem if you hear any odd noises.
2. Your Fridge Is Leaking:
A refrigerator that is dripping indicates that something is not operating correctly. If you see water collecting near the fridge, there may be a clogged drain or a broken water line to blame. As the problem may result in damage to your floors and walls, it is crucial to have a professional examine the situation.
3. Your Fridge Is Not Cooling Properly:
Your refrigerator may need to be cooling correctly for several reasons, such as a broken thermostat, dirty coils, or a broken compressor. While some problems can be resolved independently, others call for professional repair to keep the fridge from worsening.
4. Your Fridge Is Overheating:
The back of your refrigerator overheating is a red flag that something isn’t right. The compressor and other parts of the fridge may be harmed by overheating. For the best chance of stopping further harm, having a professional identity and fixing the problem is best.
5. Your Fridge Is Freezing Food:
If food in your refrigerator is freezing, there may be a problem with the thermostat or the temperature control. This issue can cause food to spoil quickly and waste energy, leading to higher energy bills. A professional can diagnose and repair the case to ensure your fridge works correctly.
