Chemist explains when ice from the refrigerator should be thrown out
Candidate of Chemical Sciences Andrei Dorokhov explained that the smell of ice by itself does not prove a refrigerant leak: more often the cause is food, dirt, or an old filter. What should raise concern is a smell combined with deteriorating cooling. With isobutane R-600a, if a leak is suspected, the room should be ventilated and open flame avoided.
