How to fix a pop machine? Electrical Advice/ Handyman?

Question

My buddy and I got this pop machine and we want to use it for an extra beverage cooler in the garage, but there is something wrong with it.

Here's what does work:
The buttons make the mechanism in the door trip
The chutes can be activated by pushing down the spring inside the machine.
The refrigeration unit works fine.

So the problem lies between the common switch in the door that the buttons activate and the actual chute release modules.

Any idea what I can try? Anyone with expertise that can IM with me to give me ideas.

I'm handy, I just don't know much about these machines.

Any suggestions of something to look at would be helpful.

Thanks!

Answer 1

You do not say what kind of machine you have. If its an old coke machine( for instants) the buttons were actuating small micro-switch's. If you have a wiring diagram( under front panel or inside door when opened) isolate one switch at a time ( turn off power and pull MARKED wires off, tape them and try machine. do this one by one and chances are you can isolate the micro that is stuck in a closed position( no/nc micro) If you are real handy, check each switch for operation by removing wires and check operation in open and closed position. with a volt/ohm meter.. Best of luck... these are worth fixing!!

Answer 2

If you got a wiring diagram with the machine, that yould help a lot. Then you could trace it out and find the fault. good luck.
