LG Dehumidifiers - Page 9 - Answered Questions & Fixed Issues

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

Dehumidifier Problem It shows Bucket Full

heatman101

The problem you described can be caused by 3 things:

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

2. The cooling coils are dirty and need to be cleaned. Turn the unit OFF & unplug it before attempting
to clean the coils with warm water and mild dish washing liquid. Then rinse and wipe dry. A light
coating of WD40 will help them stay clean.

3. The dehumidifier is being operated in a basement, where the air temperature at floor level is
below 65 degrees. When this happens dehumidifiers struggle at temps below 65 degrees F
unless it its a Low Temp model, designed for basement applications. Raising the unit up off
the floor onto a sturdy table or counter top, that can hold the weight of the unit, plus a full tank
of water, will generally resolve this problem.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Hi

The tank may be full. Your dehumidifier has a safety device that turns off the dehumidifier when the water tank is full. Usually the tank itself either presses against a switch or there's a device connected to the tank that triggers a switch when the tank is in place and full. If you've emptied the tank and the unit doesn't run, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger.

Also test the plug/lead high to common, should have power... low to common should have power.. if you are getting reading, then motor is bad.If no reading, then. The switch maybe bad.Check the motor with a voltmeter.

Plug something else in the same outlet. If it works, you know you have power to the Dehumidifier. If it doesn't work, you'll need to check for any blown fuses or tripped circuit breakers. If you have power, it could be one of several problems that are keeping it from running. Another reason that the dehumidifier won't turn on may be that the humidity level you set your unit for has been reached. If you need or desire a lower level of humidity, adjust the humidistat to reflect this. Many dehumidifiers have a safety device which senses when the reservoir is full. The tank either presses against a switch, or there may be a sensor connected to the tank that triggers a switch when the tank is full. This is to prevent any water damage to your property. Always remember water and electricity do not mix well. Empty the tank. This should solve the problem if the tank was full. If you empty it, and the unit still doesn't run, look around the tank to see if there's a switch or other device that controls the dehumidifier. Look for a bucket switch. You may be able to throw a switch by hand.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

There are 5 basic, but solvable reasons 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 mechanical unit,
uni, set the control knob to 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
problem.

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 condenser sensor may have failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helped you to troubleshoot & solve the problem.

Change the fan capacitor.

Charlie, generally, two things can cause this: An improperly installed bucket and/or the float valve in the top of the bucket is stuck in the UP position.

Remove the bucket and check for the float valve, if your unit is so equipped. Jiggle the arm of the float valve to make sure it's in the down position. When reinstalling the bucket, be sure that the bucket fits "squarely" from top to bottom into it's holder. It should not tilt down at the bottom at all. It mist make contact with the bucket safety removal switch, located on the rear wall of the bucket holder.

Hope this helps you troubleshoot and solve the problem. Thanks for choosing FixYa.

A dehumidifier is basically an air conditioner that is used only to take out the humidity. Because of that there are 2 possible causes:
1 - the water bucket isn't properly fitted - take it out, clean it and refit it it correctly.
2 - there is something wrong in the cooling circuit: either the compressor of the unit has failed because either its motor or starting capacitor have failed or the control board is no longer operational - this appears to be your case. To certify that indeed this is the case the voltages on the compressor output and sensor input from the board will have to be verified.
This is a replacement board

Barbara, are you running the unit in a continuous mode (i.e Using a hose to drain the unit)? Or is the water draining into the water collection bucket?

If you are not using a hose for continual drainage, the fan will not run constantly. It requires that, for continual operation.

Also, you may have the humidity extraction level set to high. Lower it to 35%. Also, remove and check the air intake filter, as it may need cleaning.

Dehumidifiers that are not Low Temp models have a difficult time operating in basement applications. Because the air temp at floor level is colder than at shoulder level. At temperatures between 40 & 60 degree F, regular dehumidifiers struggle to keep up. Raising it up off the flow on to a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water can really help.

I hope this was of assistance and thanks for choosing FixYa.

Because of the risk of fire from what you have described, you need to contact LG Customer Support
at (800) 243-0000. Also, if your unit is still under warranty, the parts and repairs will be covered.

First, tunr the unit OFF and unplug it for 10 minutes. Then plug it back in and turn it ON. It will automatically set at 70%. Press the - button and lower the humidity extraction level to 45% in increments of 5%. Once you reach 35% press and the - button one more time. Now the unit is set to run continuously, until the bucket is full and the unit turns OFF automatically or you manually turn the unit OFF. In case you have misplaced the Owner's Manual, I have included a link to it, that you can download and print. http://aic.lgservice.com/gcsc/dwn/main

Probably have some plastic clips on the inside, like a car dash or door cover..try using a standard screwdriver and lightly pry open could also slide off

The "L" means that the board or sensor are bad and the system thinks that the humidity is "low"therefore it will not run...
