The Sanyos (and other mini-splits) do a pretty good job of defrosting the outdoor coil,
by switching the refrigerant flow, but not using the indoor fan.
At least not that can be noticed. It might be running at 10 RPMs.. Can't hear it.
But if you put your hand under the indoor unit, you can feel a slow flow of very cold air.
Scanning the coil shows it can be down around 30F. Chills the area under the unit a little.
