Hi Everyone, hope all is well. I have a York Chiller Millennium control panel and the LED display has gone weird on it and unable to read anything. It still lights up, just showing no data info. The data cable is connected to the microprocessor board, the chiller is actual still running. would this be caused from a faulty microprocessor eprom chip or something else? I have tried changing it with another display board that was o.k, but still no reading. Then plugged the existing display board that was working ok back in and now that has no display either. Any ideas? Your help would be greatly appreciated!! Cheers.
