Problems are often caused by the compressor starting relay. This element turns the motor on and off to start the refrigerant circulation process and cool the air. Over time, the moving contacts of the device weld, “stick” and stop opening.
As a result, the compressor remains energized and continues to run continuously, regardless of the temperature sensor readings. To detect the presence of such a failure, it is necessary to use an ohmmeter.
Installation of a new relay is a complicated operation, it is better for beginners to reassign such repairs to a specialist, so as not to spoil the compressor finally. Freon leakage is not easy to diagnose at home. Refrigerant has no odor or color, it simply evaporates into the environment, causing no harm.
Refilling with freon is also better to entrust to a master who has the equipment, suitable for this type of work. The place of the leak is determined by a visual inspection of the circuit.
But the damage can be so inconspicuous that to detect it you will have to open the refrigeration circuit and drain the rest of the freon from it. Then the air is pumped into the tubes under pressure.
It must be small so as not to aggravate the existing damage, but sufficient for a successful diagnosis. A soapy solution is applied to the surface of the tubes, which will bubble up in places where the tightness is compromised.
The air is vented, the cracks are sealed, and then the refrigerant is poured into the system. In some complicated cases, when it is not possible to restore the hermeticity of the circuit on site, the refrigerator is taken to the service center for repair.
Refrigerator thermostats can have a very different designs depending on the refrigerator model. If a stem in the device is out, it is enough to simply correct its position so that the unit begins to work normally.
But it also happens that during defrosting, water gets inside the regulator. This leads to a short circuit of the electrical system, you will have to replace the entire thermostat. To perform such work, it is better to invite a master, who will be able to correctly select the element for replacement.
A faulty control module can also diagnose only a master with testing equipment. Minor malfunctions can be eliminated immediately by an experienced refrigerator maker.
But if the breakdown is complicated, you may need to have it repaired not at home, but at the service center. For example, for reflashing, the electronic control board is removed, repaired in the service center, and then installed back in its place.
Sometimes the complicated clogging of the capillary tube can be the cause of the uninterrupted operation of the unit. Usually, to correct such a situation, it is sufficient to simply defrost the refrigerator properly.
If this measure did not give results, the master will have to perform a significant disassembly of mechanisms. It is often more convenient to do this in the service center, especially since the procedure may be associated with significant releases of moisture and technical contaminants.
It also happens that in order to restore the normal operation of the refrigerator it is necessary to completely replace the worn compressor or motor. It is a complicated operation, which can be performed satisfactorily by amateur masters very seldom, it is better to call a professional.
Depending on the refrigerator model, such replacement is performed directly on-site or in the service center.
