I think going into auto defrost is a fault, it can't really be frozen on the indoor units in cooling mode unless the internal temperature is down to around freezing. Typically there is just too much warm air going over the evaporators that they could ever get chance to become cold enough to freeze.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-82935389981999936102022-05-26T10:22:00.486+01:002022-05-26T10:22:00.486+01:00That seems very bizarre.

If the coil is too cold, it should just stop the compressor while leaving the fan running until the coil warms up (I even had a cheapo £200 standalone unit which managed to do this, despite otherwise having no thermostatic control at all). I see no reason at all to mess with the thermostat or the fan speed.InfiniteDissenthttps://www.blogger.com/profile/00463076301051295104noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-14420534785153818162022-05-25T08:35:21.970+01:002022-05-25T08:35:21.970+01:00Pretty sure it is airflow.
