Understanding How a Refrigerator Works
Before we dive into the possible causes of a refrigerator not getting cold, it’s essential to understand how it works. A refrigerator uses a refrigeration cycle to cool the interior. The cycle involves the circulation of a refrigerant, which absorbs heat from the interior and transfers it to the exterior. The key components of a refrigerator include the compressor, condenser coils, evaporator coils, and expansion valve.
The Refrigeration Cycle
The refrigeration cycle starts with the compressor, which compresses the refrigerant and pumps it to the condenser coils. The condenser coils are usually located at the back or top of the refrigerator and are responsible for dissipating heat to the surrounding air. As the refrigerant flows through the condenser coils, it cools down and condenses into a liquid. The liquid refrigerant then passes through the expansion valve, which reduces its pressure and allows it to expand. The cold, low-pressure refrigerant then enters the evaporator coils, which are usually located inside the freezer or fridge compartment. As the refrigerant flows through the evaporator coils, it absorbs heat from the interior and evaporates into a gas. The gas then returns to the compressor, and the cycle repeats.
