solar attic fan *troubleshoot*
I just noticed that I have a solar attic fan on my roof while inspecting my solar pool heater panels. It has been a bit over 80 degrees today here in San Jose, CA and I did not hear the fan spinning on this fan??????? I happened to see this same fan at costco (being displayed) and I saw that the fan was spinning etc....
Is my solar attic fan not working? what can I do to troubleshoot?
thanks in advance
