Based on where you say the ice is forming you either have a Vendo or a Royal soda machine.  It sounds like you are low on freon and your unit needs to be recharged.  You will have to call a vending refrigeration tech to recharge your unit.  You might be able to get a small appliance repairman to do it as well.  If you have no one in your area to do this you can send the unit to me for repair, but it would be difficult to box up and pricey to ship, so hopefully you can find a vending repairman there.

Thanks for the quick response!

I know a small applaince guy and he sai'd he'd be happy to look at it but hasn't done vending before. Do you know where I can find the PSI, OZ or weight of the coolant for him?
