High pressure switch
When replacing the high pressure switch put in the latest version and not the original green colored one as the temp for the fan to come on is too high. Use the red, which is a lower temperature, and there maybe a newer one than that available now. The sooner the fan comes on the better for the hot summers you have in Alabama.
