Question about LG DH404E Dehumidifier
My dehumidifier is an LG Digital - I think its a 45 pint - and it stopped working on me. I believe its either a 2006 or 2007 model. The error code on the digital readout shows CH 1. After it stopped working for a couple of days I would turn it on and off to see if it would start working again and it did once for a while but now it won't and still says the same thing. I don't have the model or anything right now because I am at work but i would think they would use the same error code on all their appliances. Thanks - I don't know for sure if thats the exact model I have.
Change the sensor assembly, Part # 6877A30013M from Appliance Factory Parts in Englewood CO, about $30. Easy to change, plugs into control board, remove old temperature probe by pry T-well open with small screwdriver and then crimping back closed when new sensor is installed, about an hour start to finish, hardest part is getting all the covers off. Mine is back to working like new again!!

Thank you for identifying this solution. The sensor can also be found at RepairClinic.com for about $18.00 plus shipping. Their internal PN is 1462299. There is a new OE PN ending in "R" that replaces the old PN ending in "M".

I'll second the resolution - once the cover was off the replacement was easy and it's back humming again in the basement

Todd, there are 5 basic, yet solvable reason for what you described. Please pay particular attention to numbers 1 & 2.
1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a manually
controlled model, set the humidity extraction level on Maximum.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. 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
If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity connenser sensor has failed. These things usually occur in units that are 5 years old or older.
I hope this helps you to troubleshoot and solve the problem.

Testimonial: "Thanks. I figured it was compressor or refridgerant, but also thought possible some sort of fuse or reset. Time to clean it for real!"
There are many reasons for a dehumidifier to 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.
