You should clean your refrigerator coils once a month, and if you want to get them back to their original condition, you should first change the refrigerant in them.
After that, make sure that you have proper ventilation and that the unit has enough fresh air circulation, as well as correct humidity. Your next step should be to change the gaskets and seals. These are also important parts that should be inspected and changed on a regular basis.
Your last step would be to check and replace the compressor, depending on the age of your refrigerator. The condenser coils, evaporator fan motor, evaporator coils, jenn air fridge not cooling expansion valve, thermostat, defrost mechanism, blower fan motor, and the defrost heat exchanger will require constant maintenance throughout the life of your refrigerator.
In order to maintain optimum cooling, you must clean all parts thoroughly and properly. Failure to perform these cleaning steps will lead to a variety of problems in the refrigerator.
Cleaning and maintaining your refrigerator is important because dirty parts increase the risk of premature breakdowns. Dirty coils and gaskets may cause corrosion and can even shorten the life of the unit.
