Well you might have hit the nail on the head. It is turned down to about 3-4 watts as that was all we needed to make the path. I only noticed this last winter and this one now but guess it could have been like that from the beginning without us noticing it. Next time I have one to test I will put it in the freezer and test that. I was thinking maybe the relay or the COR switch might be not switching. The radio was made to take it better than the controller.
