solar attic fan *troubleshoot*

hi,

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

If your solar attic fan is mechanically not working, this may be a warranty issue. Passive ventilation from the attic can make the fan blade spin slowly, even if the fan is not working properly making it seem like your fan may be operating. However, under full sun exposure the fan blade should be moving very fast if your fan is operational. If you believe that your fan is not operating properly, please click the link to the left and follow the steps to help us determine the problem.
