My sl728 recently had the bearings go bad (which I replaced) but now that I have the bike together again, I cannot keep it on a specific program. For instance, I will start pedaling to turn the bike on, then I will push a program button to start a 30 minute program and the console will display the start of the program. However, the console then shows the program stopping at 29:55 remaining. Has anybody experienced such a thing and if so could you explain your remedy? Thanks! The bike has been great and I don't like the idea of scrapping it if it can be repaired at a reasonable cost.
