My Refrigerator Is Freezing Instead Of Only Cooling?

If you open up the fridge to find milk that is not fresh, or alcohol that is hot, then clearly the refrigerator is not cooling properly. If the freezer is cool, but the fridge is hot, then the parts cooling your fridge and freezer may be working correctly. When your fridge is not cold, but your freezer is, it is likely the issue is related to one of the mechanisms in your fridge that is not working properly.

If you have gone through this checklist, but the temperature in your fridge or freezer is still not where it should be, you may have a more complex issue. You might have deliberately turned the thermostat up on your fridge if you think your fridge is not cooling quite as well. Without the thermostat, your fridge will stay cold, and maybe even stop cooling, with no checks.

Thermostats switch back on the compressor when it needs to use more refrigerant to cool the appliance. Normally, when your thermostat calls for more cooling, your fridges condenser fan and compressor, located near the floor in the back of most fridges, will come on.

If the condenser fan does not work correctly, your fridges temperature may increase, and your compressor may overheat. The job of the condenser fan is to keep the compressor and coils cool, so if the compressor breaks, then the fridge starts heating up.

The evaporator fan job is to pull cold air out from the other set of coils, which is then recirculated through the whole unit – first in the freezer, and then in the refrigerator (or fresh produce section). The evaporator fan draws air over the vape coils, cooling them, then pushing air through the freezer and fridge. The evaporator vaporizes liquid refrigerant into a gas, cooling the fridge.

The thermostat controls your fridges cooling system — including your freezer — and adjusts the compressor, evaporator, and condenser. The temperature sensor is a component that measures – but does not control – air temperature inside the fridge and freezer.

The thermometer is supposed to transmit temperature readings from the refrigerator to a control board, but if it is faulty, the refrigerator is not likely to get cold. There are coils located underneath or behind the refrigerator which cool down the fridge and condense its coolant. The refrigerator might get warm slightly when you open the doors, but it is designed to maintain the cold temperatures for cooling the food.

It is standard to find most refrigerators using a fan to push the cold air in the freezer to an evaporator, which is then forced to the cooler zone to maintain the cold temperature. The cold air is cycled back and forth through an air vent. Freezer-freeze accumulation also blocks a vent, diminishing or blocking the cold air that gets to a coolers compartment.

If your freezer compartment is badly frosted, disconnect the fridge and open the freezer door to let the ice melt. It may take a full day for a badly frosty freezer to defrost, so make plans to keep perishables in your neighbors refrigerator, if you can. If ice builds up in any part of your system, your freezer should still function normally, but your fridge will be warmer.

If this happens, clear the freezer and fridge, disconnect the units, and allow the coils to thaw for a day or two. To get your refrigerator working temporarily, take off the back of the freezer, remove any built-up frost (pouring hot water on your vaporizer coils is best).

A small fan and motor are mounted next to the evaporator, helping draw air across the coils and circulating to the refrigerator and freezer. Located behind the ventilation openings within the refrigerator, usually at the back of the freezer, an evaporator fan circulates the cooling air.

If you are not feeling cool air coming through the freezer (but know that the evaporator fan is working), it is very likely that your damper is jammed, or it is stuck in a closed position. When an air damper cannot open, cold air cannot move from the freezer into the cooler compartment, making it warmer. If the air damper cannot shut, or cannot open, then air cooling affects the fridges temperature, whereas the freezer stays at a proper temperature.

If the freezer starts to make ice in the wrong places, like in vents or the coils in the evaporator, it could mean that you have the right temperature in your freezer, but an overheated refrigerator. If you can hear the compressor running, but the refrigerator is not cooling, it is most likely because of either frost-clogged evaporator coils or a stuck or broken evaporator fan. Even if everything else in your fridge is working properly, the cold air from inside the refrigerator may escape if the door seal–also called adoor gasket–is faulty. If those vents are blocked by too many items in your freezer, it could restrict airflow, which would go into your fridge.

Most refrigerators generate all of their cooling for the freezer, and then keep cooler parts of the fridge compartment cool by using the vents between the refrigerator and freezer areas. A good rule of thumb is to store lots of food items in the refrigerator, which helps keep the temperature down, but not pack it in so tight that the air cannot easily move from shelf to shelf. In your fridge, it should stop working automatically once you reach your target temperature. The thermostat is designed to automatically stop functioning once the refrigerator has achieved its set temperature.
