Hello,

As the subject line says - it won't stop working. Not just the fan, the dehumidifier itself works non-stop.

Any idea?

Thanks.

Hi,

Even if you press the off button it keeps running?

If yes, something on the board is damaged. Had trouble looking up stuff for dehumidifiers but this came up for me with your model#...

Main control board

Sorry, no. I can stop it with the button. What I meant was that it works continuously even when the humidity level is set to high, it's like a furnace or a/c that are never satisfied by the temp. that is set in the thermostat.

Thanks.

Is it collecting moisture?
Have you checked the rooms humidity level so you know if the unit should shut off when you turn it up higher?
How long have you let is run on the higher setting? 5 min, 10 min, 30 min?

OK, so it works non-stop, nearly two hours (before I shut it down) and it seems like it does not collect any moisture.

If the compressor is running but you are not collecting any moisture indicates a system problem...leaker, restriction or inefficient compressor. Leakers are common on most dehumidifiers today :(

What are Leakers? Is it possible to fix, replace anything?

System leaks = the refrigerant gas leaks out and we get no more moisture collection.

Is it possible to fix
As long as parts are available yes....but the cost is often more than it is to buy another unit.

Got ya. And I assume without some kind of specialty equipment there is no way to check if there is or isn't refrigerant gas in the system?
