be preliminarily determine that temperature sensing agent has leaked out, and it must be replaced
with a new thermostat.
4) Motor troubles and other electric faults
a) Motor windings have been burned or short-circuited between turns
7-3-5 Compressor won’t stop
Sometimes, the compressor will run continuously (for several hours or run without end), If the food
placed in the refrigerator is not too much, there may be the following two situations: i) the refrigerator
very low, this means that the control system is probably out of order; ii) the control system works
normally, and there are troubles in the refrigerating system or other parts.
1) Temperature is set improperly
a) The temperature control knob is set to the “coldest” position. This position is to be used for fast
freezing or continuous running, its temperature for power off is too low, therefore, the compressor
won’t stop and the temperature in the refrigerator becomes lower and lower .
b) Inspection method: check the temperature control knob to see whether it is set in the position
“coldest”.
2) Thermostat is malfunctioning and makes the compressor running continuously
Analysis of Trouble
When the thermostat doesn’t work normally, it will make the compressor run continuously, and hence
very low temperature will be achieved in the refrigerator. The fault is generally due to the fact that the
contacts of the thermostat cannot be released.
Remedy
Dismantle the thermostat and make a through checkup, if it is totally out of functioning, replace it with
a new one.
3) Evaporation temperature is too high in refrigerating system, resulting in lower refrigerating
capacity and hence continuous running of compressor
Analysis of Trouble
Leakage of refrigerant and clogging in a refrigerating system will directly affect its refrigerating
capacity. Due to the reduction in its refrigerating capacity, the refrigerator temperature cannot reach
its rated value, the thermostat won’t work, thus the compressor runs continuously. When the
evaporation temperature in the system is too high, the temperature sensing agent in the temperature
sensor is also hotter, therefore, the thermostat is unable to cut off the power supply to the compressor
and stop it.
Remedy
If it has been found that the refrigerant in the system is insufficient in quantity, recharge it with
refrigerant. In case clogging occurs, disassemble the part where it is blocked. If the evaporation
temperature is too high, settle this problem with an appropriate quantity of refrigerant.
4) No stoppage of compressor due to damaged heat-insulation layer inside case body and/or
door seal
