I just purchased a 1972 GMC Ice Cream truck with a cold plate freezer. The freezer's identification plate had been removed, so I have no idea what brand it is. It has one larger freezer compartment with 3 doors and a small soda compartment.
We ran it when I purchased the truck and it sounded and looked great. I ran it for a good 6 hours yesterday, and only the first cold plate ever got freezing temperature. The rest of the plates and the piping seemed to be cool, but were not freezing. a thick coating of ice formed on the pipe going in to the first cold plate.
Do you have any idea what would make only one of the cold plates get so cold and the rest not freeze at all?
