Common Problems
The refrigerator does not work:
- Check that the power is turned on and the power plug and socket are connected properly.
- Check that the car is running and the fuse of the cigarette lighter is not blown or loose.
Poor refrigeration:
- The refrigerator door is opened frequently, or the door seal is damaged and deformed.
- If the temperature inside the box or the environment is too high, avoid direct sunlight or a heat source nearby.
- Clear the frost layer on the inner wall of the refrigerator after prolonged use.
- The cooling space for the refrigerator should be ample, with at least 10 cm of space to ensure heat dissipation.
Normal phenomenon:
The refrigerator shell shows condensation; this is due to moisture in the air in contact with the surface of the low-temperature shell, which condenses into water droplets.
