I finally received a replacement lightning detector today. After replacing the detector, I had more than an hour of conditions that normally would have caused false lightning strikes (direct sunlight, >=70,000 LUX) and I received no false lightning strikes. This was only small snapshot in time, but at least the results were encouraging.
Somewhere in this thread, one person hypothesized that possibly the noise causing the false lightning strikes is from the aspirating fan and that, possibly, the noise would dissipate when the fan motor is "broken in". I can't say whether or not this is a reasonable theory, but I did notice that the aspirating fan motor sounded like it was running much-more smoothly and quietly today than when I first installed the Atlas. I just hope that the change of detectors fixes the false lightning strikes because, aside from this problem, I really like the Atlas.
