SOURCE: Compressor won't run

the over-current relay is tripping out the compressor motor to prevent excessive current through motor windings. To prove this theory, open unit, find motor wires, disconnect wires from unit, and apply 120VAC to motor using external circuit-breaker source. Run 2 minutes max. If motor continuously turns, then relay is failing. Find it by tracing wires back to source and finding a small rectangular item. If motor again quits after 2 seconds, then this motor has an internal over-current self-resetting fuse that may be doing its job of preventing an electrical overload from a dead (shorted) motor.

SOURCE: Dehumidifier runs but does not condense water.

It sounds like an issue with the control bord. This dehumidifier should have a 5 year warranty through LG. You will need to have this serviced. If it is under warranty by LG they will either refer you to a local repair shop and they will pay for the repair or they will replace it if you do not have a repair shop in your area. Call them and explain the problem to them. Make sure that you have your reciept. Here is the contact information for LG:

SOURCE: 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.

SOURCE: compressor runs, overheats and shuts down..fan does not run...

I have had the same problem. Following the advice of someone on these pages I opened the machine up and checked the fan with a meter. On my model (the 404) it has two settings so two leads; one seemed okay, the other was dead. I checked the circuit where the fan connector plugs in and I got that both speed settings were supplying plenty of juice. Apparently the fan motor is dead. A replacement runs $79 at http://www.appliancefactoryparts.com/. I ordered one; we'll see what happens.

SOURCE: The fan runs constantly. The compressor starts,

Check the compressor run capacitor first.

Why does compressor continue running, even with dehumidifier turned off?


Hello Bernard, thank you for your post!
I see that you are experiencing an issue with the Frigidaire dehumidifier, FAD704DWD, compressor consistently being on. This could be a possible issue with your control panel or sensor. Since it could be any one of these underlying issues I would suggest contacting the manufacturer for further assistance. Hopefully this information is helpful to you. -Matt

I thought the freezing up issue was resolved post cleaning of filter (didn't know there was one). Now, it will begin to run but shut off...the compressor doesn't seem to engage. How may I re


Glad to hear that cleaning the filter got us to the next step-- Congrats on the progress!
Now Tell me more about what you mean by: ..." THe compressor doesn't seem to engage."
If you can reach the compressor piping, you can tell if the compressor is 'engaging' - by noticing a drastic difference in temperature -- the outlet pipe-- usually near the top of the compressor can-- / -- and the inlet pipr -- usually further down the side or near the bottom of the compressor.
THe Discharge pipe can get VERY HOT at the top, and the Suction pipe at the lower level can get VERY COLD (likely close to freezing) at the inlet-- the lower pipe.
Be very careful!!, if the compressor has been running a few minutes-- as the outlet pipe can burn your fingers!
Anyway-- if you notice a great difference in temperature, while the compressor is running, you know that it is moving gasses thru the system-- and thus should be creating the condensing surfaces needed to cause water to be removed from the air flowing thru the coils.
Please check this, and let us know what you learn.-- then maybe we need to dig deeper--- Like where is a frost (or sweat) line appearing, -- and more about air flowing details.
Hope this was helpful- MB

Need a repair shop in the baltimore area to look at my dehumidifier runs but wont pull water


It's cold outside. If the temperature is too low, the cold coils will just frost up and you won't get much water 'pulled'.
Check to see if the cold coils actually are getting cold when the unit is running and the control is set to cause the compressor to work-not just the fan.
If the coils are cold and full of frost or ice, the room is too cold for the dehumidifier to work. You'll have to raise the temperature of the room or wait for warmer weather.
If the coils never get cold, the compressor might be bad or the unit might have lost its freon.
I wonder, though, if it's just too cool and dry right now for a dehumidifier to be pulling more moisture out of the air.
Hope this helps!

Unit runs but the coils dont get cold


The compressor should be cool near the bottom and hotter at the top. If it runs but the coil is not cool, it probably lost its charge. Developed a leak and lost all the refrigerant.

It starts with control set to max and it runs a couple of minutes and it stops so i turn the control to low and back to max it starts again and stops the same way the humidity is at 60+ so it should stay...


one of 3 possible problems,the control is faulty,you can bypass this with a jumper wire and see if it stays running, the condenser coil is dirty and is not cooling the compressor correctly and the condenser and evaporator coils need to be cleaned,i would do this first before bypassing the control,then possibly its low on refrigerant and the low pressure switch is shutting it down or the switch itself is faulty,please rate this if it helped you,thank you

The Kenmore 106.955501 dehumidifier works well when first started, coils get cold quickly, fan runs, air moves well. after 1 hr when the compressor needs to kick back on, the lights on that circuit dim and...


Hi,
The compressor will not start when it is hot or it is no longer bleeding the pressure off fast enough on the high side of the refrigeration system and it cannot start under the load. The start relay and capacitor could also be bad...that would give the same symptoms...

Fan and compressor run but coils not cold and no dehumidification is happening.


If your compressor is running but the coils are not getting cold, then you have a problem in your refrigerant circuit.....Most likely a restriction or a leak with a leak being the more likely of the two.

AmanaD545M Runs but no water comes out


if the compressor is running and the coils dont cool, then you have a refrigerant leak or a plugged capillary tube. it would cost more to fix than to but a new one. sorry but its time for a new one.

Running but not collecting water...


Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
Components Residential dehumidifiers have a cooling system made up of these primary components:

  • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

  • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

  • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

  • The circulating fan circulates the air over the evaporator and condenser coils.

Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.

Doesnt take any water out


Most dehumidiers have a "Frost Guard" thermal protector on the condensor coil. This protector will turn the compressor off should the temperature fall below 65 degrees in the basement. The condensor fan will still continue to run anticipating the restart of the compressor.
Hence, 3 things could be wrong.
1. air temp.of basement is too cold
2. Frost guard could be faulty
3. Freon leak in condensor coil.
Assuring that basement temp. is above 65 degrees is about all you can do unless you have it checked out by a technician.
