Fridge Repair

An American inventor (Albert T. Marshall) patented the first mechanical refrigerator in 1899 but today refrigerators are a lot more sophisticated, While refrigerators can differ from model to model they all operate on similar principles there are four main factors of refrigerator operation and they are refrigeration,temperature control, air flow and defrost.

Refrigeration is how refrigerators help preserve food and keep beverages cold by removing the heat from the inside of the appliance, to accomplish this a refrigerator uses a sealed system that pumps refrigerant through a set of coils, the system includes a compressor (a pump) which compresses the refrigerant in gas form into the condenser coils where the gas is condensed into a hot liquid. The condenser coils dissipate the heat as the liquid travels through them, over time these coils can collect dust, dirt and hair which prevents the coils from properly dissipating the heat. If you notice that the refrigerator isn't cooling properly, the coils may need to be cleaned. Once the refrigerant has passed the condenser coils and the capillary tube it travels to the evaporator coils which are located in the freezer. As the refrigerant liquid enters these coils it expands into a gas which makes the coils cold. The gas flows through the coils into a suction line attached to the compressor, the compressor converts the gas back into a liquid, and the cooling cycle continues. You can determine if there's a problem with this cooling system by observing the evaporator coils while the refrigerator is running, if the system is operating properly there should be a consistent frost pattern forming on all of the evaporator coils (if only one or two rows contain frost and the rest do not it’s likely that the sealed system has developed a restriction or a leak. Be aware that any repairs to this system must be carried out by a licenced technician.

Temperature control

The temperature within the refrigerator should be between 20- 40C (350- 400F) and the temperature in the freezer should be - 180C ( 00F) or lower. The temperature is regulated by the refrigerator control, depending on the model the control may be a thermostat switch with a sensor or an electronic control board that works with one or more sensors, be aware that some models will have a separate controller for the freezer. To cool both the refrigerator and freezer the control allows voltage to travel to the start relay and compressor as well as the condenser fan motor and evaporator fan motor, once the proper temperatures are reached the control shuts off the voltage to the cooling system, keep in mind that it’s normal for the temperature to vary throughout this cycle.

Air flow

Air flow is vital for refrigerators to work properly. To cool the condenser coils the condenser fan draws in air from the front of the appliance, sends it through the condenser itself and then circulates the air back out the grill. At the same time the evaporator fan draws air from the refrigerator into the freezer, the air passes through the evaporator coils which remove the heat from the air, the air then circulates back into the refrigerator continuing the cycle. Most models will have a damper door to control the air flow from the freezer to the refrigerator, this damper may be automatically controlled by a temperature control or manually controlled by the user. If the food or beverages in the refrigerator compartment start to freeze the damper door could be stuck open. If the fridge will not cool properly, but the freezer appears to be working, the damper door may be stuck closed or the evaporator fan may have failed and will need to be replaced.

Defrost

The evaporator coils collect frost as the air from the refrigerator passes through them, since frost build up can cause air flow problems. The coils require periodic defrosting, older models needed to be defrosted manually. But most of today’s models use an automatic defrost system. The basic components in this system are the defrost heater, the defrost thermostat and the defrost control. Depending on the model the control may be a defrost timer or a defrost control board. A defrost timer turns the heater on for about 25 minutes two or three times a day to prevent the evaporator coils from frosting over. A defrost control board will also turn the heater on periodically, but will regulate it more efficiently. If the control, thermostat or heater fail, the evaporator coils will likely frost over causing poor cooling in the refrigerator.

Common breaks/problems

The main problems in your average fridge include damaged starting system, electronic controls malfunctions, frost build up, freezing agent leakage from the sealed system, bad compressor, air flow restriction and lastly the fan motors will break over time. If any of these occur it is recommended to call an expert.
