It may shed some light on your problem......also, if sears will take this thing back, it would be a good time to get rid of it. Mine is now three years old, and is having the same problem. Ask sears lack of customer service department about "service flash" # SF26-751.
I hope you have better luck than the hundreds of others with the same problems.
