The cooling system is basically the same no matter what sort of freezer a consumer has. The freezer compressor will use pressure onto the refrigerant, usually freon, and moves it into the condenser. When inside the condenser, the refrigerant will go through the coils and go through a change from vapor to liquid once the heat is lost. This is why the back of refrigerators are generally warm. The cooler refrigerant absorbs the heat and reverses into vapor. It then goes back to the compressor for the start of the process.
The parts that keep the procedure of cooling working, like anything else mechanical, need to be kept. It's always great to read the manual, and frequently there are small problems which can be attended to without having to call a highly trained expert. Freezer repair, like a lot of home appliance repair works, normally isn't really too challenging for the typical problems. If the freezer is running hot (warmer than normal) it might be due to the fact that of a bad seal on the door or rotten seals. If the freezer is running however not freezing anything, there may be dust/debris/ice on the coils, it may be blocked with ice, and more. These problems can be fixed by letting the freezer get to space temperature level, using a hairdryer to melt ice, or move debris/dust. One may need to vacuum the back of the freezer by the condenser fan to make sure that there isn't really a significant buildup of dust right behind the fan. If the freezer is leaking, ensure it's level, examine the water system line, and lastly clear the drain tube. Sometimes the fix is as simple as turning up the temperature dial. When there is a coolant problem, then it's time to call the specialists. The majority of repairs in this location aren't easy (require more than the common quantity of understand how) and are possibly harmful. One can try to repair these issues, but it's much safer to just call an expert, they will understand if the freezer is short on freon etc.
