Either the humidity sensor is defective or there is possibly a thermal etc protection device that is malfunctioning.

SOURCE: dehumidifier does not collect water

The only thing you really need to check is that collector coil that the the water is supposed to condense upon, much like the "sweat" on a glass of ice water. If that collector coil is not nice and cold, then your machine needs freon or has some other serious problem.

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:

Keep me posted. If you found this solution helpful please rate it when you get a chance. Thanks - Tech101

SOURCE: My dehumidifier runs, but no water is collecting.

If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defost over night.
Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

Hello Winl, thank you for your inquiry!

I see that you are having issues with your clean filter light coming on in your Frigidaire dehumidifier. From what you are describing it sounds like a possible issue with a sensor within your dehumidifier. I would recommend consulting with your manufacturer to see if they can provide any additional assistance towards a resolution. Best of luck! -OOS

Frigidare fad704tdp evaporator not working, unit does run


Good Morning Friend,

I understand that the evaporator is not working on your Frigidaire dehumidifier, model# FAD704TDP, even though the rest of your appliance is still running. Please check the following:

    1)Please make sure there is enough clearance around your dehumidifier. There needs to be a minimum of 12 inches all around your appliance for it to operate correctly.

    2)Make sure that the air movement through your dehumidifier is not blocked. Clean the grill with the brush attachment of your vacuum. Also, clean the filter. You will do this by removing the bucket, then pulling the filter downwards. Wash the filter with clean water, and then dry. Re-install the filter, and replace the bucket.

    3)Your appliance is designed to operate between 41 degrees F (5 degrees C), and 96 degrees F (35 degrees C). Your dehumidifier will not work properly if the temperature is out of this temperature range, or the performance of your appliance will fall greatly.

    4)The "Compressor" circuit has an automatic 3 minute time
    delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Make sure the tank is fitted correctly otherwise your appliance will not turn on.

    I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

    -Best Regards-

Model BHD-301-D Will run from 1 min to 4min then shut off. I've tried all setting from 3 to top does same thing. I have a wet basement so it should stay on all the time. If I unplug it and then plug it...


There are 5 basic, yet solvable reasons 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 you have a mechanical 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 - 65 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 to trouble shoot and solve the problem. Thanks for choosing FixYa.

2 yr. old. worked great. Then started shuting down self changing setting to low. shortly after, shuts down after 3 min. no water collection, unit is hot. Took apart. Cleaned everything inside, and filter....


Robinson, it really sounds like the compressor is overheating. This may be caused by a low refrigerant gas in the compressor. Or the compressor's oil has leaked down. But, if you took the unit apart to clean it, I would think that you would have noticed an oily residue. If it is the compressor (other than needing to be recharged) it would cost almost as much to replace it, as it would be to buy a new unit.
At least with a new one, you'd have a one year warranty and more, if you purchase an extended warranty.

Hope this helped you.

I unplugged it for awhile, read thru the instructions turned it back on setting it according to the instructions and it began to work again.
