Flashing green fan ovrd switch

[Waterloo]

On my ProStar, if it sits for longer than a week, and much depends on the weather too, some, or at least one of the switches, will act up like that. It eventually goes away. I believe it is humidity or moisture in the air that gums up the electronics (micro switch) along with any dirt that will naturally occur behind the switch. Could be something as simple as that.

But, a session with Diamond Logic would not hurt, it is usually pretty good at pinpointing issues like this, at least that has been my experience.
