I've misplaced the owner's manual on a DEN 500 P. What is a good basement setting for Summer in Central Ohio? Is a manual available on line?

I bought a cheap digital humidistat at Walmart to keep an eye on the humidity in my basement. I hung it on the wall not too near my dehumidifier. I have found that the settings on the dehumidifier are misleading, but I found a setting that keeps my humidity between 40% and 55% (at around 70 degrees), as measured by the humidistat.

How do I reset the dehumifier "set humidity" back to 35. It's on 90 now.

To reset the electronics of the dehumidifier, turn the OB/OFF Switch to OFF and unplug the unit for 10 minutes. After the time has elapsed, plug the unit in and turn the ON/OFF Switch to ON. During that time out, the electronics should have reset and reverted back to the original factory settings. From there you can set them as you like.

I hope this helped you & thanks for choosing FixYa.

My Goldstar Dehumidifier keeps cutting off even though its not full of water...any help?

A few things you could try are to make sure the float isn't covered in gunk and moving sticky-like, make sure air filters are clean and the compressor isn't overheating, and make sure the humidistat (probably a knob that says drier with arrows) isn't turning the machine off because it's reached the set level.

LG Goldstar dehumidifier runs constantly

sounds like the rheostat (aka rotary swithch) is opened (fried). can get new one on for 8.19 + s/h. need to know how to solder though. otherwise you will be looking at having to buy new unit for $120+

the humidistat is inside the machine behind the control panel. it has a mylar piece that expands and contracts according to room humidity. one side is connected to a super sensitive switch that is part of the fan/compressor circuit. you could just jump this out with a piece of wire but you'll have no control over the humidity. the unit will just keep on running.

A Question

You can test the humidistat fairly easily, using a volt-ohm meter. Just set the meter to RX1 scale and attach its leads to the humidistat's terminals. Rotate the humidistat's knob as far as it will turn in both directions. If the volt-ohm meter registers zero ohms through only part of the humidistat dial's range, the humidistat is working. If it registers zero through the entire range, it's broken and must be replaced. Dehumidifier Overflow Cutoff Switch Test- Using a volt-ohm meter, you can tell if the overflow switch works or not. Clip the leads to the terminals on the switch. Depress the bar or trip lever on the switch. If the meter's needle doesn't show continuity and no continuity as the switch is clicked back and forth, the switch is probably faulty and will need replacement.
