The time it takes for a fridge to get cold can vary depending on several factors, including the model and size of the fridge, the ambient temperature in the room, and the initial temperature of the items placed inside. Generally, it can take anywhere from 4 to 24 hours for a refrigerator to reach its optimal cooling temperature.
In your case, since you mentioned that the freezer is cooling down, but the fridge section appears to be warming up, there could be a few reasons for this:
Initial cooling period: It's normal for the freezer to cool down faster than the fridge section. The freezer has a smaller volume to cool, and its temperature drops more quickly. The fridge section, which has a larger volume, may take longer to reach the desired temperature.
Airflow obstruction: Check if there are any items blocking the vents or air channels inside the fridge. Proper airflow is essential for even cooling distribution. Rearrange items to ensure proper air circulation.
Temperature settings: You mentioned having the fridge set to level 5 out of 7. However, the optimal setting may vary depending on the fridge model and its temperature control system. Check the user manual to determine the recommended setting for your specific fridge.
Seals and door gaskets: Inspect the door seals and gaskets for any damage or gaps that could be allowing warm air to enter the fridge. Replace any faulty seals to maintain proper cooling.
Room temperature: If the room temperature is particularly high, it may impact the fridge's cooling efficiency. Keep the fridge away from direct sunlight and other heat sources.
Overloading the fridge: Avoid putting a large amount of warm food into the fridge at once, as this can overwhelm the cooling system. Gradually add items to allow the fridge to cool them properly.
Given that you just purchased the fridge secondhand, it's possible that it might need some time to settle and operate optimally. To give it the best chance of reaching the desired temperature, keep the fridge closed as much as possible for the first few hours. After 24 hours, check the temperatures in both the freezer and fridge sections. If the fridge section still doesn't cool down adequately, despite trying the above suggestions, there may be an issue with the refrigerator's cooling system or components. In that case, you may need to seek the assistance of a professional technician to diagnose and fix the problem.
