[Shop-talk] dehumidifiers

[coles at colesnurseries.com (Dan Fest)]

I was given a second hand dehumidier which I thought I'd run in the garage for
a while to help dry things up.  Whenever I run it, after say 7-8 hours,
there's no water in the bin and the fins are frozen with ice on them.  Is this
one junk and I need to get another or is there a simple solution ??
Thanks,
Dan
