What are common reasons why the fridge section of a fridge freezer may not be cooling?
There are several common reasons your fridge might not be cooling while the freezer works fine. One of the primary causes could be the malfunctioning of the evaporator fan, which circulates cold air from the freezer to the fridge section. If this fan is blocked or defective, it will prevent the fridge from receiving the cool air it needs to maintain a low temperature. Additionally, a dirty or blocked condenser coil can hinder the cooling process as well.
Another reason could be an issue with the thermostat. If the thermostat is set incorrectly or has failed, it might not trigger the cooling cycle of the compressor, leading to a warmer refrigerator. Lastly, door seals that are damaged or not sealing tightly can cause cold air to escape, further impacting the temperature balance between the freezer and fridge sections.
How can I troubleshoot my fridge to find the source of the cooling issue?
To troubleshoot your fridge, start by checking the temperature settings. Ensure the thermostat isn’t set too high, as this could prevent the fridge from cooling adequately.
