I have a 1950ish Frigidaire that I want to refurbish. Is it possible/ a good idea to put more modern parts in so it doesnt use up as much electricity and is a bit safer? I also know that the freon used back when it was made is very dangerous but I'm not sure if that would be worth taking out. It is also worth noting that the fridge does work as is, the main concerns are safety and energy efficiency. If anyone has any insight or reasources they could point me to on the subject or anything to help me better understand fridges in general that would be greatly appreciated. Thanks in advance.
