Refrigerator Repair Tips: How Does It Work?
It’s advisable to know these tips for making a good diagnose by yourself, and therefore asking for the correct refrigerator repair method. So, we will talk now about how a refrigerator gets cold …
Well, it doesn’t exactly get cold, but take the heat outside from the inside: the result is the same because the temperature goes down. The main idea with the refrigerators is that they are constantly pulling the hot air outside, which makes thermometer’s temperatures appropriate for food preservation.
Refrigerator Coils
A refrigerator uses a compressor, ammonia or another refrigerant, a long system of tubing, an expansion valve and a couple of fans to chill the food stored inside. The refrigeration system is a closed loop and it cycles repeatedly to pump out the heat (or to cool off the fridge, if you prefer to think of it that way). If this cycle is not working well, you need a refrigerator repair.
The compressor does as the name implies, it compresses the refrigerant. Compressing a gas causes its temperature to rise, so it is circulated through tubing outside the appliance to allow it to dissipate heat into the room. As the compressed gas cools and reaches the location where it enters the interior of the refrigerator, it passes through an expansion valve and the pressure drops. When the gas goes from a high-pressure state to a low-pressure state its temperature drops.
A fan circulates the air in the freezer over the now very cold refrigeration tubing. The refrigerant absorbs the heat from the freezer and carries it back outside the appliance to return to the compressor again. A thermostat in the refrigerator monitors the temperature and signals the compressor when to start a refrigeration cycle. Some models have a second thermostat in the freezer for more precise temperature control. That way you can now if it is all about just changing the thermostat for a refrigerator repair.
In most refrigerators, the refrigerant passes through the freezer and then the air is circulated between the freezer and the refrigerator to lower the refrigerator’s temperature. However, in some models, the refrigerant tubing also passes through the fridge.
A side effect of the drop-in air temperature is condensation. The water in the air condenses and forms on the contents and interior of the fridge and freezer. In the freezer, it freezes into ice, resulting in frost build-up. Most freezers have an automatic defrost system to control the build-up of ice. The system simply turns cuts the circuit to the compressor and turns on a heater to melt the ice. The cycle runs for a period, the ice run-off is channeled to an evaporation tray on the outside of the appliance and when the cycle completes, the circuit to the compressor is restored. Now you now it’s all about an automatic defrost system when calling a professional for a refrigerator repair.
When the refrigerator or freezer door is opened, a door switch turns on the interior light. In some cases, the switch also disables some circuits, such as the interior fan or the through-the-door ice and water service.
