[Free To Roam]

Thanks for the thermistor info.
It was one of the first things changed, made no difference. Drat!
I am leaning toward your suggestion on the residential model, however, I too bought the extended warranty, so, I think I will continue to hound them for that "extended" period of time.
The more input I get from this post, the more I am convinced the unit is just plain defective.
Thanks again....
