Vending Machines

Inspection of the refrigeration unit has yielded it's dead.



Corrosion ate through the piping at the lowest points, allowing the freon and lubricant to escape. When the compressor was powered it hummed angrily and the ammeter took off so it's rightfully seized.

Good news is that instead of hacksawing the lines so I can at least salvage the evaporator which is a rather specific fit to the machine there are threaded couplings I can loosen to separate it from the dead assembly. Leaves hope that int he future a new compressor and evaporator can be found.

Weather finally improved. Had the base of the machine soaking in WD-40 for a few days and almost all the screws came out so I could remove the bottom and get at the worst of the rust.



I'm using three different discs to clean up the rust and prep for fresh paint. First I'm using a regular grinding wheel to remove the scale and the larger chunks of rust, then I switch in the stripping wheel which brings it completely down to clean metal. From there these areas are sprayed with a rust converter. From there I have a flap sanding disc I will use to clean up the entire cabinet before it is reprimed and painted.



Need to borrow a sandblaster though to clean the smaller parts and areas I can't reach.

Edited: This is the little fan that was at the bottom of the door. There seems to be a cavity that runs parallel to the doors and blows air over them. I assume to prevent condensation?



I never plugged the machine in, so the blown coil must of happened years ago. The fan spins freely. Shouldn't be too hard to find a replacement motor.
