What are important considerations when replacing a control board?
Anytime a replacement board is installed, the most up-to-date programming must be available and the owner’s manual for the machine must be on hand. The manual is essential if there are problems in the cabinet or to identify parts by their OEM number. The programming may also be needed. If you do not have these documents, you should hire a vending service professional to install the parts.
We recommend taking a picture of the harness connections to the original board before installing the replacement board.
Here is an overview of the most common boards:
National Vendors 15x, 16x, GPL 159
These boards will default to “Temporarily Out of Service” when they are first installed. The type of machine, bill validator, coin changer, and pricing will all need to be programmed before the board will function. If the machine is equipped with guaranteed vend, it should be enabled. If you have an MDB card reader, it must also be enabled. If the display does not come on, look at the way the ribbon cable is attached because it can be installed backwards as it is not keyed.
Rowe snack and Royal Vendors soda
Clarify that the “Door Open” switch is in good condition because they often break.
AP 120 and Studio series
In many cases, the board will need to be reset. Follow the procedures that are provided in the manual.
Stack soda vendors
The programming instructions are usually printed on a large decal on the barrier door. If the software on the board was changed, these instructions may not apply.
Rowe dollar bill changers
Clarify that the software matches with the version of power supply; Fast Pay or Double Dump
Capital Vending kits
If the installation instructions are lost, they can be downloaded from the website. Search YouTube for instructional videos as they are available for the popular parts and board kits.
