8-1. Abnormal phenomena
Problems Reasons Removing methods
Compressor
can not be
started
1. Fuse is broken
2. The contact of plug, socket, and cable is not
good. Cable broken.
3. The voltage is too low, 10-15% less than rated
voltage
4. The knob of temperature controller is at “rest”
position.
5. The temperature controller is out of order.
6. Starting relay or thermal protection unit is out
of order or broken.
7. Wire broken of motor starting coil or operation
coil.
8. The compressor motor is burned or rotator
and stator are blocked to dead.
9. There is leakage of high-pressure gas valve or
the shaft is embraced to dead.
1. Check if there is short circuit and
solve it, if not, change capable fuse
2. Check and connect tightly, or
change.
3. Use till voltage rises to rated value
or attach a stabilizer.
4. Rotate the knob to wanted position
for suitable temperature.
5. Change the controller.
6. Change starting relay or thermal
protection unit.
7. Measure using R×1 position of
avometer, if there is wire broken,
change compressor.
8. Change compressor.
9. Change compressor.
Compressor
starts too
frequent,
operation time
too long, but
temperature
drop in wine
cellar is too
slow
1. The point of sensor was moved.
2. The temperature controller is out of order.
3. The environment temperature is too high,
humidity too high, airflow is impeded.
4. The frost layer at the evaporator is too thick.
5. The refrigerant is insufficient or leakage.
6. Compressor efficiency is reduced.
7. The drying filter is blocked.
1 Check the point of sensor, and move
it to original place.
2. Change the temperature controller.
3. Put the wine cellar to suitable place
and make air circulate well.
4Remove frost regularly.
5. Check or supplement refrigerant.
6. Change compressor.
7. Change new drying filter.
Compressor
runs without
stop,
temperature in
freezer is too
low
1. The point of sensor was moved.
2.The temperature sensing probe of controller is
not placed well, and causes maladjustment
3. Compressor efficiency reduced.
1. Check the point of sensor, and
move it to original place.
2. Adjust to suitable position, normally
contact tightly with evaporator cover.
3. Change compressor.
