Unit fan running but does not take any moisture out of the air....bucket has not even a drop in it for three days.....moisture on floor even in basement area


There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1, 2 & 5.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If yours is a manually
controlled unit, set the 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 model). This applies mainly to
where the air temperature at floor level is colder than at shoulder
in basement applications level. 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.

Hope this helps you troubleshoot & solve the problem

My LG LHD45EL all of a sudden


Short on refrigerant... or a failed compressor. are most likely or a system problem, causing it to trip off.

There may also be a failed electrical component, you need to check for voltage at the compressor.

A7DH45B2A Dehumidifier: Can anyone help me understand why my dehumidifier ...


The biggest reason is plugged filter...or te coil bhind the filter is plugged. Then you get into whether the compressor itself is running or not. Just because the fan is running does not mean the compressor is

Kenmore 54501 turns on but nothing happens in my damp basement


A dehumidifier heats and cools the air to remove moisture. Most are like a small air cond. The Condenser coil is right in front of the evap.coil. So the compressor may not be coming on. Does it sound the same as before? It may be low on freon. You will have to get in there and listen and feel the lines at or near the compressor, Learn how to get down in there to the compressor. Run it for 10 Mins. unplug it, open it up, and feel the lines. Some lines should be or can be HOT to the touch. Some should be cool. The smaller the line the hotter it should be, and the compressor should be warm (to hot) to the touch. repost for more info.

LG LD65EL Dehumidifier doesn't work properly


What do you have the humidity level set at on your dehumidifier? The average is 65%. Make sure you do not have it set at 75% because if you do this could be causing it to keep the humidity so high.
