Question about Midea Dehumidifiers
The compressor runs and cycles ok but no water is extracted from the air. The humidity control is set below the ambient humidity. The filter is clean and so are the fins.

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.
Thank you for your allowing me to advise you on this issue.

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:

If you haven't done so already, try removing and cleaning the inlet filter screen which is almost certainly just behing the inlet grille. It may slide upwards out of the casing or downwards unto the bucket area. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry, in which case the compressor will probably not run.
A running compressor can usually be detected as a deep throbbing from the machine. If it is running, but not cooling the pipes behind the intake grille, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this may be the cause.
Explore along these lines and let me know what you find.

dehumidifier doesn't seem to run often but the humidity in the room is
high, try adjusting the humidistat control on the dehumidifier to a
dryer setting. If the dehumidifier seems to run constantly, but there's
little or no water in the container, there may be a problem in the
refrigeration system. Try cleaning the unit. If that doesn't work, you
can't repair the refrigeration system yourself, you need a qualified
appliance repair technician to do that.
Hope that helps! Should you have any further questions, please feel free to post them here.

My unit does not collect water any more. It was fine until I lent it to my brother in law and it was returned damaged. Do you know how to fix this
