fhamann Posted June 16, 2018 Share Posted June 16, 2018 I have an old USI Snackmart II Model 2099. It has been trouble free for over a year but now has the following problem: When a product is purchased, the coil only turns 1/4 turn. If you make the same purchase, it will turn another 1/4 turn. In other words, it takes four vends to turn 360 degree complete circle. This happens on every selection. It does the same thing in the service mode when I test each selection. What could be causing this? Would replacing the control board fix this? The control board costs around $200. Thanks for your help or opinions. regards, Frank Hamann Orange, CA Link to comment Share on other sites More sharing options...
Snack Man 2000 Posted June 16, 2018 Share Posted June 16, 2018 This may sound crazy, but did you try resetting it by turning the power off for a bit, then back on? I have cleared up a lot of issues that way. Link to comment Share on other sites More sharing options...
fhamann Posted June 16, 2018 Author Share Posted June 16, 2018 Yes I did. Problem did not go away. Thanks for the idea. Link to comment Share on other sites More sharing options...

I have a lot of those machines, and haven't ran into that issue. Did you inspect the wiring, especially around where where it hangs down on the trays? It sounds like a short to me if there's no other issues going on. Use a bright led flashlight is you haven't. Link to comment Share on other sites More sharing options...
AngryChris Posted June 16, 2018 Share Posted June 16, 2018 I think i had a similar problem. I think there was a wire that was shorting out or something. I think the board was bad too. I fixed the problem by replacing the machine. Link to comment Share on other sites More sharing options...
CajunCandy Posted June 16, 2018 Share Posted June 16, 2018 I had a AP machine would do the same thing! It was the board! Link to comment Share on other sites More sharing options...
Corvus Corax Posted June 19, 2018 Share Posted June 19, 2018 Have you tried pulling the trays and test one at a time. If it is a short that should narrow down where it is. Link to comment Share on other sites More sharing options...
fhamann Posted June 19, 2018 Author Share Posted June 19, 2018 Hi Corvus, I just did the test as you suggested above. I pulled each tray out one at at time and did a vend. The problem remains. The coil only turns 1/4 turn. It was a good idea anyways. I have decided to send the control board to STA Vending : http://www.s-t-a.us/stavend/vending-machine-control-boards-repair.php They said that they can test the board and repair the board for $110 plus parts. If the board tests good, they change $45 for the test. Link to comment Share on other sites More sharing options...
