A refrigerator is one of those appliances that is used in almost every home and runs continuously 24/7, keeping your food fresh and cold. If it breaks down, then there is nothing to worry about because we will discuss everything related to repairing your refrigerator. After reading this article, you will definitely be capable of repairing it yourself. In this way, you will be able to save yourself a costly repair bill.
We will start with basic information. A refrigerator consists of two fundamental coils: a condenser coil which is located outside the unit and an evaporator coil which is placed inside. Today most refrigerators are frost-free. Usually in this type of unit, the heater is automatically turned on and off.
When frost starts melting, the thermostat automatically turns on the cooling cycle in order to maintain the standard temperature. As mentioned above, it is an automatic process so frost will never build up inside the unit.
The unit capacitor system is totally dependent on a capacitor type motor which forces the coolant to move through the coil system. Some other basic parts of the cooling system include switches, thermostats, condensers, and fans.
Now we will come to the repair process. To avoid any risk, it is advised to make sure that the refrigerator is unplugged. Next, check whether the motor has a capacitor or not. If it does, then it is located at the top of the motor. As we all know, capacitors store electricity, even without electricity or when the power is off.
So before working on a capacitor-type refrigerator, you must discharge the capacitor, otherwise you will receive a severe shock.
After discharging the capacitor, the next step is disassembling the refrigerator. The components are divided into two sections, the upper section and lower section. Usually the control components are located in the top section and the motor, compressor, and fans are located in the bottom section.
One can easily gain access to these sections by removing the screws or metal panel over these parts. The condenser, compressor, and the evaporator coil are sealed on most refrigerators, and if a problem occurs in any of these parts, one has to call the manufacturer’s service person.
A lot of problems can be resolved by servicing the refrigerator door. Ideally, a refrigerator should maintain the temperature up to 40 degrees Fahrenheit, but of course, the door opens many times a day, so here are a few tips to keep warm air away from the food.
The unit’s efficiency sharply drops when a refrigerator gasket, a rubber that is sealed around the door, becomes hard with the passage of time. In order to test it, place a dollar bill in between the gasket and door, and then close it.
After some time, pull the bill out. If it offers some sort of resistance, then it means the seal is working properly, but if the bill falls out, then the gasket should be changed immediately.
Many problems are also solved by servicing the defrost timer. If a compressor isn’t working, then it means that the timer is malfunctioning. To test it, one needs to unplug the refrigerator first, then disconnect the wires from the defrost timer and the motor and then safely remove the timer. Similarly, one can place the new timer by following the above-mentioned procedure.
