My Danby DDR583R dehumidifier no longer dehumidifies unless I set the humidistat to the lowest, constant run setting--then the compressor kicks on. The humidity reading says 14% which I know to be erroneous. I suspect the humidity sensor is not working. I see where they run around $23. Is this the correct diagnosis and how easy are they to replace for the average, somewhat technically savy person?

There are a several things that can mimic a faulty humidity sensor.

1. The air intake filter is clogged and needs to be removed and cleaned.

2. The coiling coils need to be cleaned.

3. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If the above fails to help solve the problem, replacing the Humidity Sensor is certainly an option. But, before you jump into it, make sure you have an accurate wiring diagram, so you know which sensor is which. As the part does not come with installation instructions.

I hope this helps you and thanks for choosing FixYa.

I have the same problen traced it to the humity sensor. Where do you buy one. Dany can not supply. Is there a subistute?

Simply cleaning the dust accumulated on the filter solved the issue of compressor not turning on, Danby Model DDR45E
