[Shop-talk] dehumidifiers

[Brian Kemp]

Dan - I had a similar problem with an old Kenmore I picked up for $10.  
It would ice up below about 65 degrees.  At 70-80 degrees it worked fine 
and got a similar amount of water compared to my new dehumidifier when 
both were run at the same time.

There are dehumidifiers for room temp and ones for lower temperature 
ranges (search 'dehumidifier low temp').  I saw the other replies on it 
being low on refrigerant and agree it could be a factor, but I'd also 
try it in a warm location before junking it.

One option I did for a while was to take a small electric heater and 
have it blow towards the air going into the humidifier.  This helped 
lessen the icing most of the time back in my single days when I didn't 
run the heat in my apartment.

As a side note, the old dehumidifier was run a bunch with my first 
daughter.  We used it to get her to sleep by putting her in her car seat 
carrier on top of the unit (it was wide and flat).  The steady noise and 
vibration worked surprisingly well.
