1. Common Faults Analysis and Maintenance Measures
①
Question: Displayed temperature is not the same as actual test temperature:
Answer: As the displayed temperature is the temperature at one point in refrigerator, while a
user is testing the temperature of another point in refrigerator, as position is different,
temperature must be different, meanwhile, the user’s testing tool may have certain
measurement error with our temperature detector.
②
Question: The temperature difference between upper part and lower part in refrigerator is
too large:
Answer: As our machines start refrigerating from up to down, the upper part temperature is
lower than lower part, meanwhile, the temperature difference is large. The temperature
difference of like products in the world is 5~8
℃
, basically, our temperature difference is
maintained around the temperature. In addition, if a user open and close refrigerator doors
frequently, big temperature difference between upper part and lower part may appear.
③
Question: What is voltage ‐ increase start?
Answer: To ensure the normal operation of machine, our machines have the functions of
increasing and decreasing voltage. When a user’s voltage is lower than 183 V, the machine is
unable to start, at that time, the user needs to check if his line is normal or not;
④
Question: A user has set ‐ 86
℃
, why it rises up to ‐ 82
℃？
Answer: To ensure the service life of machine, our products are designed as the followings:
when ambient temperature is higher than 32
℃
, if setting temperature is lower than ‐ 82
℃
, it
will return to ‐ 82
℃
, if ambient temperature is lower than 32
℃
(including 32
℃
), it will return
to original setting;
