Analysis on FAQ (frequently asked questions):
If the condenser is dirty or clogged, it could not cool the compressed gas produced by the work of
refrigerant compressor. When it is overheated, the compressor may be damaged. Therefore, the
condenser must be cleaned on a regular basis to keep clean.
If the freezer is installed close to a wall, it may lead to bad ventilation. In this case, once ambient
temperature reaches 32 ,
℃ the condenser temperature would rise rapidly, seriously affecting the
refrigeration system. Therefore, such measures must be taken as reinstallation, ventilation improvement
or installation of air-conditioning system to ensure that ambient temperature is kept below 27
℃
(especially in hot summer or tropical zone).
Unstable voltage or under-voltage may result in abnormal running of compressor. The rated voltage
of compressor is 380V±10% (or 220V±10%), beyond which it is recommended to install a voltage
stabilizer.
If the freezer is installed in a closed room with air-conditioning system, it may be damaged due to a
steep rise of ambient temperature in case of air-conditioner failure, especially on festivals and holidays
or at night, so a monitoring system should be installed.
Emergency measures
In case of any fault or any other emergency,
1. immediately move the samples stored in the freezer into a safe freezer in the vicinity.
2. turn off power switch.
3. contact and report the fault to local Haier After-Sales Service Center to have it clear soon.
Common troubles and solutions
The freezer does not work
At first, check whether the air switch is tripped and whether power failure of external power
network occurs, if the fault is not caused by the two reasons, check whether the AC contactor coil of
compressor control board is energized; if energized, there is nothing wrong with the control board, and
then check the circuit to compressor or compressor condition; if not, there is something wrong with the
control board.
