Danby dehumidifier ddr4588ee ices up.
According to your Owners Manual, the coils may start to frost at 60 degrees and the defrost sensor should turn ON and cycle periodically. However, the air temperature at the floor level in a basement, is colder than the air temperature by 5 to 8 degrees. So this may be causing the problem. In addition, if the air intake filter is dirty or clogged, the unit has to strain to keep up and will not function as it should.
If the unit is totally iced up, turn the unit Off and unplug it from the wall outlet. Allow is to thaw completely before attempting to clean the filter. You may want to put some old towels under it while it thaws. Once it's thawed, move it to a bathroom that has a shower. Plug it it in and set the humidity level at 45%. Turn the shower ON at a Medium hot temperature (enough to generate steam) and as you exit the batroom, close the door. DO NOT operate the bathroom's exhaust fan. Allow the unit to operate for 15 to 20 minutes, before returning to the bathroom. Then turn the shower OFF and check the unit for any frost and the amount of water collected in the bucket. If there is no frost on the unit and there's water in the bucket the unit is operating properly.
When you move it back to the basement, place it up off the floor on something sturdy, that can hold the weight and not be bothered by the vibration of the unit, when it's running. (ie a work bench, a counter top, etc.) Operate the unit as you normally do and monitor it for frost or icing up. And, whether or not the defrost sensor is cycling as it should. If you get no frost or just minor frost, it was the air temperature at the floor level, that was causing the problem.
Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
