Hmm, good to know. I do tend to keep the thermostat set at 67F, would
be lower if not for SWMBO. My natural comfortable temperature is about
65-66F. The basement probably is always cooler than the rest of the
house. Obviously it will be hotter in the summertime when I have the
thermostat set for cooling but spring and fall definitely the coolest
part of the house.

Stay away from the Sears Branded dehumidifers -- I've had nothing but
problems with them.

I like the Whirlpool 50 and 70 pint ones that are at Lowes [and other
places]. They're energy star rated and they are designed to operate at the
lower temps [upper 50's].

I keep my basement and crawl spaces at about 35-40% which has worked out
quite well.

we have always been pleased with kenmore dehumidifiers!
you might also benefit from have a small fan, moving the air around down
there!

Yes our smallish Kenmore, in a 35 by 46 foot, approx 40 year old,
mainly unfinished basement is tending to freeze up and clog the coils
with ice; even at a minimum setting especially during each winter.
Temp. of our mainly below ground basement tends to be around 50 deg.
F.
So tend to agree the low temp, in our only occasionally heated, plus
some heat loss from main floor above, is likely cause of frozen-up
coils.
As an experiment have put a standard desk fan to blow at the coils,
which seems to help a bit. At least dissipating more quickly, the ice
that forms, whenever the dehumidifier compressor cycles off!
Also thinking of rearranging so that the the built in dehumidifier fan
runs all the time unit is plugged in; regardless of whether compressor
is running, to more readily dissipate ice formation; won't be the
whole answer but may help?
The compressor cuts out of course when the water reservoir fills up.
May rig an alarm to this to warn need to empty. Another alternative is
to run the drainage into a basement floor drain all the time.
Any thouhts. Also have another older but very similar model (obtained
free at a flea market!) which doesn't seem to work as well.
