kevinnguyen Posted June 8, 2017 Share Posted June 8, 2017 I just installed the new red logic board for the DN 5591. Everything's working fine except for the screen. It keeps blinking "Enjoy the Fresh Drink" which is supposed to be solid. However, when I go to the service, test, set up mode, the screen is solid. I heard that I need a new display board and a new harness. Please tell me if they're cause that problem. If anyone have them for sale, let me know.

AZVendor Posted June 9, 2017 Share Posted June 9, 2017 Yes, the red board needs a newer energy star display board and harness. I believe I have those in stock so email me at rbepic4gatgmaildotcom. Link to comment Share on other sites More sharing options...
