Hey Heather,
I wish I could remember which model I have but I have a schwin recumbent bike and have had it for about 2 year. No problems though so I cant be much help except to tell you we use it alot and it hasnt happened to us. Thats a bummer it has so many neat features. Sounds dumb but have you tried unpluggin it and leaving it off for a while then trying again, just a thought.
Sorry I couldnt really help
