Today you can find different types of refrigerators in the market. Although there are different brands and models of refrigerators, they all operate based on the same principles. We can identify the four major factors that describe operations of refrigerators and also some of the most common problems you are likely to encounter and would need fridge repair near me service for.
The 4 main factors of refrigerator operation include:
- Refrigeration cycle
- Temperature control
- Airflow circulation cycle
- Defrost system
Refrigerators are useful appliances for food preservation and keeping beverages cold, so they require Onsite refrigerator repair in case of problems. They essentially do that by taking away heat from inside of the appliance and releasing it outside of the appliance. In order to accomplish that, the fridge makes use of a system that is sealed and pumps refrigerant to go through coils. This system also has a compressor, a water pump that is used for compressing the refrigerant white in gas form into condenser coils. The condensation process converts the gas into a hot liquid. Heat is released into the environment as the liquid continues flowing through the condenser coils. With time, the condenser coils may attract a lot of dust and dirt. This can make the coils not to release heat to the environment as they should. So if you notice a problem with the refrigerator not cooling properly, one of the things you may need to do is to clean the condenser coils. From the condenser coils, the refrigerant will travel through a capillary tube and then into the evaporator coils. These evaporator coils are located inside the freezer. Inside these coils, the liquid refrigerant will be converted into gas and that is what makes the coils cold. The gas will flow through the evaporator coils and then into a suction line which is attached to the compressor. The compressor then will again convert that gas into a liquid and the cycle of cooling will continue. By observing the evaporator coils you can easily determine if there’s any problem with the cooling system. Whenever the system is working normally frost on the evaporator coils assumes some consistent patterns. But if the frost is only seen in just some of the rows, then probably there is a leak or a restriction. If there’s any problem with the cooling system, it is important to have it only repaired by a technician who is highly trained, licensed and certified.

Within the refrigerator, temperatures need to be about 35 – 40 degrees Fahrenheit. Inside the freezer, it should be 0 degrees Fahrenheit or lower. A refrigerator control is used to regulate temperature. The control may include a thermostat switch combined with a sensing bulb assembly or an electronic control board that uses sensors. It depends on the model of the refrigerator. Some refrigerator models will come with a separate control for the freezer. In order to cool the refrigerator and also the freezer, the control will allow voltage to flow to the start relay, the compressor and also the condenser fan motor as well as the evaporator fan motor. The control will only shut off the flow of voltage to the refrigerator cooling system when proper temperatures are attained. It is also normal for the temperatures to vary throughout the cooling cycle. Qualified refrigerator repair atl techs can help with any temperature control problems.
It is important to recognize that airflow in refrigerators plays an important role to make them work properly. The condenser fan in the refrigerator draws air from the front of the appliance and sends it through the condenser coils in order to cool them down. The air is then circulated out through the grill. At the same time, the appliance uses an evaporator fan to draw air from the refrigerator and sending it into the freezer where it passes through to the evaporator coils to remove heat before circulating it back into the refrigerator. The air circulation cycle then continues. Some models of refrigerators use a damper that controls the airflow between the freezer and refrigerator. A temperature control can automatically control the damper or the user can manually control it. If food and beverages stored in the refrigerator compartment start freezing, the damper door could be stuck open. When the refrigerator is not cooling properly but the freezer is working just fine, the door could be stuck closed, or it could be the failure of the evaporator fan and that would need to be replaced through brookhaven appliance repair service.
Remember the evaporator coils usually collect frost due to passage of the air from the refrigerator through the coils. Since the build-up of frost will normally affect airflow, periodic defrosting of the coils is necessary. For the old models of refrigerators you will need to manually defrost them. An automatic defrost system is normally used for most of the refrigerator models available today. This system usually consists of basic components that include the defrost heater, defrost thermostat and defrost control. Depending on the refrigerator model, the defrost control may be in the form of a defrost timer or even a defrost control board. The defrost timer is the one that turns on the heater for about 25 minutes, 2 or 3 times every day, in order to prevent evaporator coils from frosting excessively. The defrost control board can also be used to turn on the heater on a periodic basis, but it regulates it more efficiently. In case there is a failure of the control thermostat or the heater, then the evaporator coils are likely to frost over and that will cause poor cooling inside the refrigerator. Both the thermostat and heater can be tested for continuity which determines if there’s a continuous electrical path. If they test positive for the continuity, that means the control is faulty and requires replacement. So look for LG appliance repair company nearby to help you out.
