| Basic troubleshooting of can soda vending machine (1) Problem: Machine will not vend, all money comes back to coin return when inserted. Possible solutions: Make sure machine has cans in it. If entire machine is empty it will not vend. Possible solutions: Make sure that there is not a ‘credit´ on machine, once vend price has been reached the machine will not take any more money until selection has been made by pressing button. Possible solutions: Make sure that the machine is loaded properly. If any one column has a can jam due to improper loading or other reasons then the entire machine will be out of service. Carefully remove the motor cover panel (possible shock hazard, don not work with live power) and see if all of the motors are in their ‘home´ position. There are wheels on the motors that turn and switches that ‘drop´ into notches on these wheels. This notch is the home position. If the motor is not in the ‘home´ position then it is likely that you have a jammed can. With power to the machine ‘off´ and clear the jam from the column that is not ‘homed´ by manually removing the cans from that column until empty. After jam is cleared turn on power and motor should ‘home´ on its own. (2) Problem: Machine will not take dollar bills (for machines with validators). Possible solutions: Make sure that there is change in all of the changer tubes (5,10,25 cent coins) of the changer (TRC6200 nickels, dimes only needed). Possible solutions: Make sure that the harness to the dollar validators has not come unplugged from the machine or the validators. (3) Problem: Machine will not cool. Possible solutions: Check lower fan to see if it is running. If it is not running the thermostat could be turned off or bad. The thermostat on Dixie Narco is usually located below motor cover in the right hand side of machine, below the can chute on the right wall of the cabinet. Vendo machines have the thermostat located towards the rear wall of the cabinet below the can chute on the left hand side of the machine, right in front of the evaporator fins. All of the way counterclockwise turns refrigeration off. The farther you turn to the right the colder the machine gets. Be careful not to turn too cold or cans will freeze. Remember diet drinks freeze at a higher temperature than regular drinks. Most machines have an electrical plug from the refrigeration unit plugged into a black box on the lower left hand side of the machine. Unplug this plug and plug it into a heavy-duty extension cord. If the compressor unit comes on (along with lower fan) then that basically proves that the thermostat has probably gone bad. |
