Had a dehumidifier given to me because "it overheats" . Inspecting the
unit I find that the evap coil is icing - which if I remember my
refrigeration correctly is an indication it's a little low on refrigerant .
Once the coil is totally iced , there's no air flow thru the unit , which
will overheat the compressor ...
Other than a slight vibration on the casing , this seems to be the only
problem . Is my memory correct ? I have access to everything needed to add
some R22 , including the gas .
This unit will be used in our camping trailer , assuming I can get it to
work right , the second one is going in my shop - gotta keep the machines
from rusting !
