Unstable temperature

Solutions: If the problem lies in control board, replace it; if lies in compressor itself, replace it or its accessories.

Internal temperature does not reduce, but rises, e.g. rises to -80℃from -140℃. Cause 1: Dirty condenser or clogged air vent

Solution: Clean the condenser

Cause 2: Slowdown of fan speed

Solution: Replace the fan

Cause 3: The freezer is extremely close to a wall

Solution: Move it far away from the wall for good ventilation

Cause 4: The freezer is placed in a closed narrow space

Solution: Install an air-conditioning system and improve ventilation condition

Cause 5: The freezer is not left still for a sufficient time and is energized before its system reaches stable state, resulting in the problem of “oil beating” taken place in the compressor.

Solution: Turn off the freezer, leave it still over 24 hours, and then turn it on, gradually reduce the temperature setting from -126℃by following corresponding operating instructions.

Cause 6: The samples loaded at a time are over 1/5 of the freezer’s effective capacity, or the samples loaded are too hot (20℃ higher than the temperature setting, e.g. the samples temperature is -106℃or above and the temperature setting is -126℃). In this case, the load of freezer greatly increases, so the compressor works for a prolonged time, and thus causes the temperature rise of compressor, steep reduction of refrigeration effect as well as imbalance between the cold energy provided by the refrigeration system and the loss of cold energy for the entry of ambient air, finally resulting in the rise of internal temperature.

In this case, it is the fault of user for he/she uses the freezer as a quick freezer. However, the appliance is a SLT freezer for maintaining the low temperature of articles with only a little refrigeration and requires all the articles to be cooled down to basically equal temperature before being put into it. If the user fails to follow instructions described in this manual, the continuous
