Q:
My machine will not take in bills but accepts change ok.
A:
Several options here but the most common especially when first setting up the machine is that there is not
enough change in the changer. By looking at the display it will give you a clue as to what may be wrong. If the display
reads “Please Insert Exact Money….” that indicates there is not enough change in the changer. Fill the coin tubes
completely full. Completely full means you can’t get any more change into the coin tube. Press the coin return button and
the display should show Canceling. The display should now show “Please Insert Money…..” without the word Exact.
Q:
My machine still will not accept bills and the display does not indicate Exact change.
A:
If the validator takes in the bill partially but ejects it back out, that indicates that the bill may be unacceptable or
the validator needs cleaning. Check for a jammed bill behind the bill box. Follow the validator manufacturer’s
recommendation for cleaning.
Q:
My machine will accept $1 bills but not $5 bills.
A:
This situation can depend on several factors. Make sure the bill validator is set to accept $5 bills. The amount of
change being reported in the changer must accommodate the highest vending price in the machine, so make sure the
changer is full of change. If you are vending high priced items you may need to replace the changer with a larger capacity
model.
Q:
My machine will not accept the new $5 bills.
A:
Contact the bill validator manufacturer for upgrade instructions. Not accepting currency that has been changed
due to a Federal Government mandate is not covered under our manufacturer’s warranty.
Q:
My machine will vend a product, display Vend Error then give my money back or allow me take make an
alternate selection.
A:
This indicates there is a problem detected with the vend motor. Each vend motor has a small micro switch inside
that indicates when the motor has made one full revolution and returns back to what is referred to as the “home position”.
If this signal is not received back to the controller in a specified amount of time the controller will indicate and error and
refund the money. The problem could be in an individual motor itself, the tray wire harness or any connection in between
the tray to the control board. If the whole tray acts this way that usually indicates that the tray harness or any connection
in between to the controller may be bad. The easiest way to troubleshoot this situation would be to swap tray connections
where the tray harness plug plugs into the machine. For example it the problem appears on the A tray, unplug the A tray
and the B tray (assuming they both have the same number of selections), swap the connections and plug the A tray into
the B tray receptacle and vice versa. Now do your test vending by selecting the B selections on the keypad and the A tray
should operate. If the problem follows the tray then suspect either the motor or the tray cable harness. If the problem
stays with the A receptacle and now the B tray exhibits the problem then the problem is in a connection somewhere
between the A receptacle and the controller board. Make sure to examine any and all connections for any loose wires,
etc.
Q:
My display is dead or intermittent but the rest of the machine appears to be working.
A:
Check the gray flat ribbon cable connection between the display and the controller board to insure the plugs are
plugged in securely.
Q:
My machine will not cool.
A:
1. Make sure the machine programming is set up properly so that Zone 2 is enabled and the proper temperature
limits are set for Zone 2. Zone 2 lower should be set around 37 degrees and Zone 2 upper should be around
5-6 degrees warmer. If the temperature is set too cold then you risk the chance of evaporator freeze over.
2. On models equipped with a refrigeration fuse make sure it is not blown. The fuse needs to be a 20 amp Slo-
Blo fuse.
3. Inspect the evaporator coil to see if it may be frozen over. Using a flashlight shine it into the 3 evaporator fans
located under the bottom tray. You are looking for aluminum fins behind the fan motors. If they are completely
white or solid with ice this will keep the air from flowing properly and cause the machine to not cool. To thaw
out remove the 3 prong condensing unit plug, not the evaporator fan plug and just close the door and let set
