From Wikipedia's 'History of the Refridgerator':
"Commercial fridge and freezer units, which go by many other names, were in use for almost 40 years prior to the common home models. They used toxic ammonia gas systems, making them unsafe for home use. Practical household refrigerators were introduced in 1915 and gained wider acceptance in the United States in the 1930s as prices fell and non-toxic, non-flammable synthetic refrigerants such as Freon or R-12 were introduced."
Prior to WWII, people looked to the past for answers, now they look to the future for salvation. Indy realizes he must fight what is toxic, with what is toxic. Thus TECHNOLOGY plays a big role in this film that it does not play in the others.
Plus, a fridge is a suburban-conformity-family-item. This is a 50's movie. That will be a big element that old-Indy will have to be accustomed to.
