[Shop-talk] Dehumidifier suddenly freezing up

[Jim Franklin]

> Jim - Check airflow.  Is the filter clogged?  Did you put a box next to it
that reduces air circulation?  After you turn it off for a while and let all
the ice melt, does air blow out when you restart it?  It should move a
noticeable amount of air.

Those aspects are fine, freezes in minutes even when I remove the filter.
Great airflow, no clogging, no obvious blockage, though for grins I'll try to
check the hot coils which are on a fine mesh of radiating grills behind the
cold ones and hard to get to.

and greater capacity.  It was well worth the $150 I paid at costco.com about
10 years ago.  If you buy a replacement, pay attention to look for one rated
for basements.  The ones that are not basement rated have a greater potential
to freeze in cooler temperatures.

Good to know, thanks!
