Why is there such a big difference between the set temperature and the actual temperature displayed on the beverage refregrator?

Why is there such a big difference between the set temperature and the actual temperature displayed on the beverage refregrator?

There are two potential reasons:
1. The refrigeration system is broken.
2. The temperature probe is broken.
Let the customer test it with a thermometer to see if the temperature has not changed. If yes, it shows the probe is defective, If no, the refrigeration system is defective. Please kindly contact customer support to process this issue.
