The common components found in all types of refrigerating equipment regardless of their construction type, are the mercury switch, the capacitor, and the door gasket.
|Mercury switch||Sensor for lid closure on chest coolers||In the appliance cover, behind the control lights.||Drop of silvery moving liquid encapsulated in a sealed glass capsule, which might be protected by a case.||Mercury (Hg)||Mercury switches need to be removed for separate treatment. Make sure not to break the vial. Store separately to avoid shock. Keep it in a sealed recipient, in a cool place away from any heat sources or direct sunlight.|
|Capacitor||Capacitors are required to assist the startup of asynchronous single-phase motors||Capacitors may be present in all types of refrigerators and freezers and are located close to the motor||Capacitors are cilindrical in shape and have at least two electrical connections (tabs or wires sticking out)||When dealing with older appliances, Capacitors may contain PCB. PCB-free condensers with castor oil have been used in more modern appliances (since approx. 2000).||Capacitors need to be removed for separate treatment|
|Door Seal||The seal ensures airtight closing of the refrigerator door.||The seal runs around the perimeter of the door's inside face.||The seal is an elastic ribbon, usually white.||Door seals are usually impregnated with fungicides, i.e. treated with biocides.||The seals are barely suitable for recycling. The door seals can be frequently replaced, i.e. easy to remove. However, this is not always the case for all appliances and manufacturers.|
Insulation can consist of foam panels or vacuum insulation panels, which both require a different strategy.
