Although mechanical refrigerators have gone a long way since their invention in 1899 in terms of appearance and choices, the components and mechanics at work remain mostly unchanged: Refrigerators employ evaporative refrigerant compounds to keep them cool. The temperature of the refrigerant reduces as it evaporates from a liquid to a gas, keeping the box where your food is kept cool as well. A compressor, condenser, evaporator, capillary tube, thermostat, and sealed refrigerator box are required for the system to function
properly. If any of these components fail, the whole refrigeration process may be jeopardized. All types of equipment may experience defects. This is not uncommon and does not mean that the refrigerator should be disposed of. Rather, it is a good idea for the owners to look into the signs. In this way, the defects can be detected and remedied at an early stage. Help from an instruction manual, forums, or a fridge repair company can quickly find the faults.

If you need expert assistance with your refrigerator, you may be unsure whether to contact an appliance repair specialist or an HVAC technician. The fact is that it is dependent on the problem’s nature. An appliance repair professional is more suited for a problem that seems to be more directly tied to the actual device—for example, a problem with the control board or thermostat. If the problem is more complicated and involves the refrigerant system, an HVAC specialist may be the best choice.
The main reason that users identify is that the internal temperature in the refrigerator is too high. This can have various causes. Whether it is a permanent drop in performance or a spontaneous defect, errors can be ruled out. Sometimes several spare parts need to be replaced. Defects can be prevented by regular customer service. Most problems occur after the warranty period has expired.
The most common problems
Not all defects require the replacement of parts. Here are some examples.
● Dirty condenser coils: These cannot dissipate heat to the ambient temperature or can do so only to a small extent.
● Thermostat: The set temperatures cannot be reached due to the missing function. The compressor runs too much or not at all.
● Ventilation motor and fan impeller: Due to jammed objects or a defect, there is a deterioration in cooling performance.
● Start relay: The relay gives the signal to the compressor to start running. This is indicated by the lack of humming in the refrigerator.
● Capacitor: A multimeter can be used to detect or rule out this defect. If used continuously, the inexpensive replacement parts will burn out.
● Control module: Because of the defect, parts of the technique are not controlled. Knowledge of electrical engineering is assumed to repair
Repair on your own
Regardless of the method of troubleshooting, refrigerator repair requires knowledge. The repair service has the necessary tools, specific equipment, and its pros know how to deal with all kinds of problems. Knowledge and tips can be gained from studying Miele, Bosch, Siemens, or other brands. The design of appliances of different brands has differences. Although you have to spend a lot of time on your own repair, you should consider visiting a specialist on-site. His advantage is that he has all the parts to repair the refrigerator. A look at the insides of the refrigerator brings further understanding and knowledge of the appliances. Some parts are readily available and can be purchased for a small price. The cost of repair is limited to replacement parts in the case of a do-it-yourself repair. The decision must
be made individually.
