wiktionary
The noun is a clipping of refrigerator, perhaps influenced by the Frigidaire brand of refrigerators, or frigerator(“(dated) refrigerator”). [1] The verb is derived from the noun.
From fridge(“to place (something) inside a refrigerator to chill”), alluding to “women in refrigerators”, a phrase coined by the American comic book writer Gail Simone, who criticized a plot point in Green Lantern (volume 3, issue 54, 1994) in which Kyle Rayner, the Green Lantern, comes home to discover that the villain Major Force has murdered his girlfriend Alexandra DeWitt and left her body for him to find in the refrigerator. [2]
Probably imitative of the sound of chafing or rubbing. [3]
etymonline
fridge (n.)
shortened and altered form of refrigerator, 1926, an unusual way of word-formation in English; perhaps influenced by Frigidaire (1919), name of a popular early brand of self-contained automatically operated iceless refrigerator (Frigidaire Corporation, Detroit, Michigan, U.S.), a name suggesting Latin frigidarium "a cooling room in a bath." Frigerator as a colloquial shortening is attested by 1886.
