Definitely does it at lower temp settings but only if air runs for more than an hour or so. Sounds like the fan shuts off but compressor continues. In less than ten seconds the fan comes back on in a low setting for about a minute, then normal ops. It does this three or four times over a 30 minute period then runs normal for a few hours. Never really timed it.
One AC guy I talked to said it had to do with defrosting some part up there. Probably not related but he said be sure all filters were clean, including removing the top shroud every 4-6 weeks to verify no dirt, blockage, etc.
