Product Overview
Royal came out with this updated version of their Merlin IV control board around the beginning of 2018. The old version of the Merlin IV is not available new any longer; rebuilt versions of the old style Merlin IV control board are available on our website occasionally as part #VT2378.
This kit includes a required new selection switch harness that is serial number-dependent (that is why we require your machine's serial number before you checkout).
Royal has a couple different board kits depending on the age of your machine. In general, the kit in this listing will fit any bubble front soda machine that uses a Merlin IV control board, and was manufactured prior to 2012. The board kits for Red Bull machines, and Royal Merlin IV soda machines manufactured after 2012, are different board kits. Search for them on our site to find them, or call us at 970-623-1272 if you have any compatibility questions.
