Failure of a relay or control module, lack of power supply, thermostat, and compressor malfunction are just a few of the main reasons why your LG fridge may not work.
To diagnose the malfunction of your refrigerator, it is advisable to follow the following sequence of steps:
check that the power cord is plugged in;
Check whether the power cord has external mechanical defects (insulation breakdown, breakage on the plug side, etc.). If this is the case, it must be repaired or replaced;
check that the power supply to the house/apartment has been organized (there may simply be no power in the mains).
If, after such manipulation, the equipment does not work and the following points are present:
a light is on in the refrigeration compartment but the compressor does not start (no humming sound);
There is no indication on the display;
there is no effect when switching the thermostat;
the fridge is not unlocked (problem with the control module);
There is excessive humidity in the fridge compartment for reasons beyond the user’s control,
Your refrigerator requires servicing by a qualified technician.
Thermostat malfunction
No effect when switching the thermostat. It is more common for the thermostat to break the bellows tube, which cannot be repaired. The only reliable and effective way of rectifying the fault is to remove and replace the thermostat.
LG refrigerator compressor does not start
The absence of characteristic noise and sharp increase of temperature in a freezing chamber testify to it. Incorrect installation of the equipment, sudden changes of voltage in the electric mains, and non-observance of operating conditions are only a part of the reasons for the failure of the compressor.
LG fridge does not turn on after defrosting
It can be caused by several reasons: the compressor is damaged and there was a leak of freon, foreign objects have got into the system of cooling and there was a clog, the mode of work of the sensor simply isn’t exposed. Depending on the category of fault, it can be rectified by:
– repair of the freon pipes (rectification of mechanical defects by soldering);
– replacement of the compressor;
– cleaning the cooling system from blockages.
Either way, a full range of diagnostic measures must be carried out by a qualified technician.
Relay or control module malfunction
The control module is the “brain” of the refrigerator, responsible for the correct functioning of all systems. If this function is not working properly, the electronic controller is defective. It malfunctions due to causes independent of the operating conditions: air and water leakage or voltage fluctuations in the domestic power supply.
If you are not qualified to deal with technical faults in the cooling unit, it is best not to repair the unit yourself. This will not only make the situation worse but may also damage your health.
