My Refrigerator Has Suddenly Stopped Cooling?

When your refrigerators blower is running, that means both your defrost timer and your coolers cooling controls are set to COLD. If either fan is out, or if the compressor is not running, then the refrigerator is going to provide very little or no cooling. If the fan in your freezer is still working, but the fridge is not getting any cooler, it may be that either the compressor or compressor startup relay is bad.

If your condenser fan motor is bad, you may be getting colder fridge, but there is no cooling at all in freezer section. The condenser fan motor circulates cool air from the evaporator coils through the compartment. The condenser fan motor is responsible for cooling the air, and it is a probable culprit if your refrigerator or freezer is not cooling correctly.

The job of the condenser fan is to keep both the compressor and the coils cool, so if the compressor breaks, your refrigerator starts heating up. If the condenser fan does not work correctly, your refrigerators temperature could go up, and your compressor could get too hot.

If a refrigerators condenser coils become dirty, it cannot cool the refrigerant enough, and internal temperatures may increase. If coils are dirty, your fridge is not running effectively. Over time, coils – that are not located inside the sealed box – may get smeared with dust, hair, or pet fur, which will decrease their ability to keep air inside your fridge cool.

The coils spread the heat from inside the fridge outside to the room, using the help of the fan. With all of this gunk caked on to the condenser coils, the coils cannot disperse the heat as effectively, which leads to higher temperatures inside the fridge.

We rarely think about this, but that heat being removed from the interior of your refrigerator has to go somewhere, and that is what the condenser coils are for — getting rid of that extra heat so that the inside of your refrigerator stays nice and cool. Clogged condenser coils can result in a bad circulation of air, restricting the cooling capacity of your refrigerator. Overloaded refrigerators cannot properly circulate cooling air, and it is even possible for items inside the refrigerator to clog cold air intakes.

If boxes of food are blocking a vent, the cold air can get blocked from getting through the refrigerator. Freezer ice accumulation also blocks a vent, decreasing or blocking the cool air that gets to your coolers compartment. If anything blocks the cold air, this could cause uneven temperatures inside the refrigerated compartment.

The Freezer might function properly if a bad Air Damper is working properly, but cold air might not get to the Refrigerator. If your evaporator fan is not working, there is no way for cool air to reach your fridge.

Your fridge contains two fans, which are an important part of keeping your appliance running, and if these are not working, it could be a reason why your refrigerator is not getting enough cold air. Your fridge has both an evaporator coil in it, as well as circulator fans, located in the freezer area. There are coils located underneath or behind your fridge which cool down and condense your fridges refrigerant.

A closed-loop refrigerant takes heat and moisture from an internal storage area, mostly the freezer, and runs it through a set of coils, which pull the heat out and scatter it to the air. As the refrigerant passes through condenser coils under high pressure, it cools down and turns back to liquid. The Evaporator Fan pushes air over the Evaporator Coil, cooling it, then pushing air across your Freezer and Refrigerator.

The evaporator fans job is to draw the cooled air out from the other set of coils, so that the whole unit is circulating – first through the freezer, and then the fridge (or fresh food section). When a fan stops working, it cannot circulate the cool air within the food compartment. Because of its insulation, The circulating fan cannot pull air across evaporator coils.

Poor cooling may result from excess ice buildup over the vaporizer coils. If a frost timer goes bad and stops working in cool mode, this causes excess frost buildup on the evaporator coils, reducing airflow. If A defrost heater goes bad, excessive frost builds up on the coils reducing the cooling air flow within your cooler.

Without a working fan, it is easy for the fridge to get too hot and stop cooling as designed. This seems an obvious one, but sometimes thermostat dials are set too low, which causes the temperature of your fridge to go up. Even if everything else in your fridge is working properly, the cold air from inside your fridge can be lost if your doors magnetic seal – aka door gasket – is not working properly.

Instead, your fridge might have dirty condenser coils, doors that are not sealing tight, or defective temperature controls. If you can hear the compressor running, but the fridge is not cooling, it is more likely the issue is either frost-clogged condenser coils, or the condenser fan is jammed or broken. If your refrigerator is not cooling but the freezer seems to be doing fine, the problem may be the evaporator fan.

This would lead to problems with the compressor of the refrigerator, which is the part that circulates refrigerant throughout the system. Normally, your refrigerators condenser fan and compressor, located near the floor in the back of most refrigerators, turn on when your thermostat calls for extra cooling. The condenser fan is located in the lower portion of the fridge, near the compressor and condenser coils (note that refrigerator models that have their condenser coils located at the rear, rather than at the bottom, will not have the fan).
