What could cause a DN501R to OCCASIONALLY vend product from the wrong column? Apparently sometimes when the "Coke" button is pushed, it vends from the 7-Up column. It must be sporatic because when I put money in or put it on test vend, everything works fine. Any ideas?

it usually has to do with the vend command thru the motor switch being interfered with....d/n 501 are notorius for this wierd problem and it has to do with moisture in the switch....if 7-up is dropping when another item is selected, start by changing the vend switch on the 7-up motor, it most likely has drawn moisture, and since they operate on lo-level voltage and are wired in series with all the other motors, tis type of symtom will occur....What could cause a DN501R to OCCASIONALLY vend product from the wrong column?

also , if this does the trick...dont throw the old switch away....throw it on the dash of your truck for a few days....i have seen them dry out and then they are ok to re-use.....
good luck barry

Thanks Doug. This is the machine we have at work. I haven't experienced that problem with any of mine. I'll start with the switch.
