My Freezer Is Running Too Warm?
If your cooling system fans and compressor are working, but your fridge or freezer is not cooling properly, check to see if there is a problem with the airflow or the defrost system. Normally, the fridges condenser fan and compressor, located near the floor in the back of most fridges, turn on when the thermostat calls for extra cooling.
The thermostat, which controls the temperature, allows electricity to be routed to the compressor, the evaporator fan, and the condenser fan. The compressor is a motor that compresses refrigerant and circulates it through evaporator coils and condenser coils.
The condenser fan circulates air over the condenser coils, helping to cool down hot refrigerant coming from the compressor. The fan chills condenser coils, which are usually located close to the compressor in the lower back portion of your cooler. An evaporator fan is located in the freezer compartment, circulating cool air through the refrigerator while its compressor is running.
You might be having an issue with the motor of the evaporator fan, which ventilates the evaporator coils during periods of compressor operation, and is located in the refrigerators freezer compartment. Like in an ordinary refrigerator, a bad evaporator fan or iced-up evaporator coils may result in the refrigerator compartment being hotter, even though the freezer compartment remains cool. If your refrigerator is too full, this can prevent air circulation, which is a common cause for warm refrigerators.
Obviously, the freezer will do just fine in this example, but the refrigerator is going to get way too hot. If you have a cold freezer, but your refrigerator is hot, then there is a chance the parts cooling your fridge and freezer are working correctly.
If a fan is not working, no cool air is reaching the compartments. It is standard to find most fridges using the fan to push the cold air in the freezer into the evaporator, then this air is forced to the cooler section, keeping it at a cooler temperature. Your fridge relies on the flow of air from a ventilation system between the freezer and the fridge areas to keep temperatures stable.
Refrigerator coils work to cool and condense the refrigerant, helping keep the air flowing through your fridge cooler. Your refrigerator works by spreading out cold air in order to keep the contents of your home cold.
Overfilling the freezer could clog a ventilation duct, and stop cool air reaching a hot freezer. A bad door seal lets warm air through and lets cold air through, which is cold enough that it will keep the freezer from freezing. A malfunctioning defrost function could result in the evaporator coils getting stuck with ice, preventing your refrigerator from cooling properly.
If the refrigerator is working, a defrost timer, defrost heater, or defrost thermostat could be at fault. If the control board in the refrigerator is malfunctioning, it might not adjust temperatures properly so that your refrigerator stays cool enough to store your food safely. If the sensor becomes damaged or defective, it can misdirect an electronics control board to shut down the compressor and fans, causing the fresh food and freezer temperatures to get warmer than normal.
If the compressor and fans are operating normally, but are not running frequently enough or for long enough to maintain proper temperatures in the fresh food and freezer sections, the refrigeration controls may be flawed or off-calibration. If the fan motor for the evaporator is defective, the temperatures in the freezer section will increase slowly, while those in the fresh food section rise faster, and the compressor will operate longer and more often than usual. If the temperature of your appliance is warmer than normal and the compressor is running nearly constantly, you might have a condenser fan motor issue.
If the condenser fan is not running when it is turned on, then your refrigeration temperatures are going up, and your exterior walls are likely feeling extremely hot to the touch. When the fan is malfunctioning, it might feel like you have an okay freezer, but the fridge feels warmer. A blown-out or covered blower will not efficiently circulate air, and it can cause your fridge to get hot too.
A faulty thermostat is failing to send electricity to your refrigeration system, and if this happens, the freezer is not cooling. If a thermostat is damaged or defective, it will not register temperatures accurately, this in turn can make the freezer feel too hot.
If the fridge is not getting cool enough, it may have a faulty temperature-control thermostat. The temperature control is the switch that supplies electricity to the refrigerators compressor and fan circuits.
Electronic control boards are connected to temperature sensors which automatically monitor conditions inside the refrigerator, using that data to control the units BE, fan motors, and defrost systems. The temperature sensors, or thermisistors, are responsible for providing the sensor inputs which controls the time when fans are turned on. This component performs many essential functions inside a freezer. This component regulates temperature, controls fans, and activates the defrost heaters and compressors.
With most fridges, you will find the compressor at the rear of the unit, near the floor. The compressor is the part in your appliance that makes that particular buzzing noise that we are used to hearing from fridges and freezers.
The evaporator takes heat out of a refrigerator, chills the contents, and turns chilled refrigerant into hot steam. The cooled refrigerant flows through the expansion valve to the evaporator. The condenser coils convert refrigerant from vapor to liquid, releasing heat–the same heat you feel when it is blowing around your refrigerator during the cooling cycle.
If you hear the compressor running, but the refrigerator is not cooling, it is more likely that you have either frozen-clogged condenser coils, or an stuck or broken condenser fan. A problem in the defrost system in the freezer could be causing the evaporator coils and other components of the refrigerator to freeze up, which will stop it cooling properly.
