How do you know it's bad?
My red lite wouldn't come on when I tested it at home before this trip we are on now. At home it was 55 degrees outside.
I got to sunny, spend the winter in comfort, Arizona where the temp was 22 degrees.
I turned on the water bay heater light came on and it actually warmed up the bay enough to thaw my water lines.
So I think the outside temp has to be low enough to allow it to come on.
