Why is my refrigerator not cooling, but the light is on?
It’s common for a refrigerator to have its interior light on while failing to cool. This issue could be linked to a malfunctioning compressor or a problem with the fan responsible for circulating the cold air inside. When the compressor doesn’t operate correctly, it doesn’t generate the cool air necessary for maintaining the proper temperature. Similarly, if the fan is obstructed or damaged, it can’t effectively distribute the cold air throughout the fridge.
Another potential issue could be a clogged airflow vent or dirty condenser coils. If the coils are coated with dust or debris, it impairs the refrigerator’s ability to cool down efficiently. Regular maintenance and cleaning these components can help ensure your refrigerator functions properly. Always check if any foreign objects might be obstructing the fan or air vents to help resolve this cooling issue.
