AngelCity Posted June 15, 2017 Share Posted June 15, 2017 My usi snack machine has a coinco ba30b with a coinco changer (not sure of model). Twice now the changer has spit out the whole quarter tube when someone purchased something. Thankfully their honest people! Anyone know why? Is it the changer? The acceptor? Something else? What should i replace? Any info is helpful! (Except coinco is garbage, i already knew that) Link to comment Share on other sites More sharing options...
AZVendor Posted June 15, 2017 Share Posted June 15, 2017 Check for dim, flickering or burned out florescent lights in or near your machine or in the ceiling. They can send confusing electromagnetic pulses to the logic board and cause this issue. USI machines are very sensitive to this and if it goes on too long it will damage the logic board. If all bulbs nearby are good then it might be a bad coin mech but in the SM3 machines it can be a bad mech and logic board together. Link to comment Share on other sites More sharing options...
AngelCity Posted June 23, 2017 Author Share Posted June 23, 2017 Seems like all bulbs around are ok... Would replacing coin mech be a good start? Link to comment Share on other sites More sharing options...
AZVendor Posted June 24, 2017 Share Posted June 24, 2017 Try the mech first and see if the problem comes back. If so then do the board. Link to comment Share on other sites More sharing options...
