Has anyone ever had a problem with the recirculation mode working in reverse? Meaning when it's on it draws outside air and when its off it recirculates inside air. Tested it yesterday and could tell it was drawing colder outside air with it on (fan only). Tested with the AC on but couldn't tell the difference. Usually there is a increase in air speed or volume when you recirculate. They was none. Sparky's reset procedure was performed a couple times.
