When your refrigerator stops cooling, it can be a stressful and potentially costly issue, especially if you have perishable food items that are at risk of spoiling. However, before you call a professional or consider replacing your fridge, there are several steps you can take to troubleshoot the problem. In this article, we will explore the common causes of a fridge not cooling and provide you with a step-by-step guide on how to identify and potentially fix the issue.
Understanding the Basics of Refrigeration
To effectively troubleshoot a fridge that’s not cooling, it’s essential to have a basic understanding of how refrigeration works. The refrigeration process involves the transfer of heat from the inside of the fridge to the outside, using a refrigerant that changes state from liquid to gas and back to liquid again. This process is facilitated by a compressor, condenser coils, and an evaporator coil. The compressor compresses the refrigerant, causing it to become hot and high-pressure, while the condenser coils dissipate this heat to the outside air. The refrigerant then passes through an expansion valve, which reduces its pressure and allows it to expand and become cold. This cold, low-pressure refrigerant then passes through the evaporator coil, where it absorbs heat from the inside of the fridge and causes the temperature to drop.
