If the Mijia Refrigerator Side-by-Side 621L cannot reach the set temperature, please check as follows:
1. Check if an excessive amount of food or food that is too hot has been placed inside. This can cause the temperature to drop slowly. Please wait for the temperature to drop.
2. Check if the ambient temperature is too high. The refrigerator's operating environment is 10 °C to 43 °C. When the ambient temperature exceeds this range, the cooling performance may decrease.
3. It is normal for there to be a slight temperature difference between the actual temperature and the set temperature, because the air inside the appliance is circulating and the compressor does not run continuously.
4. Check if the door is closed properly. If the door is not fully closed, a large amount of cold air can escape, reducing cooling performance.
5. Check if the door is opened too frequently. Frequent opening can cause a large amount of cold air to escape, reducing cooling performance.
6. Check if the door seal is tight. If not, please adjust the door seal. Use a hairdryer to evenly heat the door seal, but be careful to use a low speed and avoid deforming the seal. Then, smooth out the seal by pressing it along the door frame. After it cools down, the door seal should be properly set.
7. If the issue persists, please request an after-sales service inspection.
