I have a Kenmore 65 pint dehumidifier that does not dehumidify. The compressor and fan both run. The environment is 70 deg, 60% humid. I've cleaned the filter and coils. The fins are clean. When I touch both sets of coils they are room temp (I expect one set to be cold). I set the dehumidistat to 40% (it only has 40,45,50). Any suggestions?
