I don't know whether you ever got an answer to your query, but I'd suggest you have a look at the Sears support site at
www.managemylife.com. (Don't ask me, I didn't name it.)
You don't mention how old that model is, but if you have no luck there, try
this site and it's possible there's one there or a similar model you can download that will provide the needed info for you.
Good luck.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
