Yes, if a refrigerator is placed too close to the wall, it can potentially cause cooling issues. Refrigerators require proper airflow around them to dissipate heat generated by the compressor and other components. When the refrigerator is too close to the wall, it restricts the airflow, leading to a rise in temperature around the refrigerator's condenser coils.
As a result, the compressor may overheat and shut down as a safety measure to prevent damage. When the compressor stops working, the refrigerator compartment will no longer cool properly. However, since the freezer usually has a separate evaporator and cooling system, it may continue to work fine, or at least stay cold for a while.
It's essential to maintain proper clearance between the refrigerator and the surrounding walls or cabinets as recommended in the manufacturer's guidelines. Generally, you should leave at least 2-3 inches of space on all sides and at the back of the refrigerator to ensure adequate ventilation and prevent cooling issues.
If you suspect that the proximity to the wall is causing the cooling problem, try moving the refrigerator slightly away from the wall to improve airflow. If the cooling issue persists, it may indicate a different problem that requires professional repair or attention.
