Understanding Your Refrigerator’s Functioning

Refrigerators are essential appliances that help keep food and drinks fresh for a longer period. Understanding how your refrigerator functions can help you identify and solve problems when they arise.

The main components of a refrigerator include the compressor, condenser, evaporator, and expansion valve. The compressor compresses the refrigerant gas, which then flows through the condenser coils located at the back of the fridge. The condenser coils release heat, causing the refrigerant to condense into a liquid.

The liquid refrigerant then flows through the evaporator coils located inside the fridge. As the refrigerant evaporates, it absorbs heat from the air inside the fridge, which cools the interior. The expansion valve regulates the flow of refrigerant, ensuring that the fridge maintains the desired temperature.

If your fridge has gone warm, it could be due to several reasons. The most common causes include a faulty compressor, clogged condenser coils, or a defective thermostat. Other factors that can affect your fridge’s performance include improper ventilation, overloading, or leaving the door open for too long.

Regular maintenance, such as cleaning the condenser coils and checking the door seal, can help prevent issues with your fridge. If you notice any problems, it’s important to address them promptly to avoid further damage to your appliance.
