We have a three year old LG DH404E dehumidifier that no longer collects water. Power is getting through but it will not kick on even if we set the humidity level to 35%. Occasionally I can get it to kick on by repowering up. However, it kicks off after a couple minutes. What should I do and what brand is not made by LG? I need an alternative.
Best way to check the humidistat is with a digital or analog meter. Put the ohm meter on R1 if it's an analog meter. Put the two lead wires from the ohm meter on the humidistat connectors(pull off the wires,but remember where they go) while turning the humidistat knob the analog meter needle will move at a certain point then return to zero. If you have a digital meter the OL (open line) numbers will go to OO or a resistance reading will appear (such as 6.90 or 12.75 (these are just example numbers). If the humidistat is working,then throw away the unit, the freon is low or leaked out . Not worth fixing then. You can Google "humidistat" on dehumidifiers and also find ways to troubleshoot this item. Even a simple humidistat costs around 30 bucks,IF you can find one out there for your model.
Sounds like a faulty humidistat, but may also be nearly out of freon. I have a GE unit that is also a portable air conditioner...works great for 5 years now...
There are many reasons why a dehumidifier will not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier
