    Unit does not deposit moisture in tank, but moisture does drop on floor under unit. Have unplugged unit for short time and replugged unit to electricity and installed hose to unit for external moisture removal

    No water extracted. Filter is still as clean as new. Removed back and front and found that black wire that attaches to one of the copper coils is rusted at the attachment point. This unit was only used for a few months. Can this be repaired or is it not worth it?
    Thank you.

It runs but no water is coming into the tank


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 an analog unit
set the humidity extraction knob 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
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 has 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.

I hope this helps you ro troubleshoot & solve the problem. Thanks fr choosing FixYa.

2 years old unit would not extract moisture from the air. Had another unit on which was working ok. How could I fix this problem?


There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. However, running to dehumidifiers in the same proximity may be the problem. ON is doing the lion's share of humidity extraction, leaving little or nothing for the other to extract.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,

the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air

Gayle, your unit has some age on it, but it may still be salvageable .

There are 5 basic, but 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%. Or set to Maximum if yours
is a manually controlled unit.

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

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 has failed. These things usually occur in units that are 5 years old or older. As far as repairs are concerned: The unit is 14 - 16 years old and the cost to repair, may be as much (or close to it) as purchasing a new unit. If you decide to purchase a new unit, be sure it's a "Low Temperature" model, as yours is being used primarily in a basement application.


I hope I have helped you and thanks for choosing FixYa.

My lg DEHUMIDIFIER model #LHD65EBL is no taking in any water. Cleaned the filter and coils.Installed the basket properly.Set the setting at 35 to70 and nothing happens. just runs. About 4 years old.


According to your Owner's Manual. once the humidity extraction level is set at 35%, you should push the minus (-) key one more time to turn the unit ON. It will now run continuously no matter what the humidity level is until the bucket is full.

In case you have misplaced your Owner's Manual, go to the link below and click on English. The Owner's Manual will download and you may print it for future reference.
