What are the most common reasons why a refrigerator stops cooling while the freezer works?
The most common reasons include a faulty thermostat, a blocked air vent, or issues with the evaporator fan. The thermostat regulates the temperature inside both compartments, so if it’s malfunctioning, it may fail to signal the refrigerator to cool effectively. Additionally, if there’s frost accumulation or an obstruction blocking the air vents that circulate cold air between the freezer and refrigerator, this can lead to an imbalance in temperatures.
Another potential cause could be a refrigerant leak or compressor issue. The compressor is responsible for circulating refrigerant, and if it’s not functioning properly, the cooling process will be affected. It’s also possible that a dirty condenser coil may be preventing the refrigerator from operating efficiently, as it loses the ability to dissipate heat effectively. Regular maintenance can help prevent these issues from arising.
