In this article, we delve into the mystery behind why your refrigerator light may be on but fails to cool, providing valuable insights and troubleshooting tips to help you restore your appliance’s functionality and peace of mind.
Understanding The Refrigerator’S Cooling System
Refrigerators rely on a complex cooling system to maintain the desired temperature inside. The cooling process begins with the refrigerant, usually a gas or liquid, circulating through the evaporator coils. As the refrigerant absorbs heat from the air inside the fridge, it becomes a low-pressure gas and moves to the compressor.
The compressor then compresses the refrigerant, increasing its pressure and temperature, before sending it to the condenser coils located outside the refrigerator. Here, the refrigerant releases the absorbed heat into the surrounding air, causing it to cool down and return to a liquid state. The now-cooled refrigerant flows back to the evaporator, restarting the cycle.
Understanding how these components work together is crucial in diagnosing cooling issues in your refrigerator. If the system is disrupted due to a malfunctioning part or lack of proper maintenance, it can result in the refrigerator light being on but the unit not cooling effectively. Familiarizing yourself with the basics of the cooling system can help you troubleshoot and address such problems promptly.
