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 !
