Let’s unravel this chilling mystery together.
Understanding the Basics of Refrigeration
Before diagnosing the problem, it’s essential to understand how refrigerators work. At the core of a refrigerator’s operation is the refrigeration cycle, which involves several components working together to transfer heat from inside the fridge to the outside environment. The major components include:
- Compressor: This pumps refrigerant through the system.
- Condenser coils: Usually found at the back or bottom, these coils dissipate heat created by the compressor.
- Evaporator coils: Typically found inside the fridge, these absorb heat from the interior.
- Expansion valve: This controls the flow of refrigerant into the evaporator.
In a properly functioning fridge, the evaporator coils inside the fridge absorb heat, causing the internal temperature to drop, while the compressor expels heat through the condenser coils.
Common Reasons Why Your Refrigerator Is Not Cooling
When your refrigerator isn’t cooling while your freezer seems to be working just fine, it could be due to several factors. Below are some of the most common reasons:
