20 Most Recent LG LHD459EL Dehumidifier Questions & Answers


Sounds like its compressor is pulling too many amps trying to start, thereby blowing the fuse. That would indicate that the compressor is most likely locked up. If so, it's time to replace that dehumidifier. Repair by a shop is far too costly, and you're better off using those bucks to buy a new unit.

There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture/humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

We had a similar situation and the problem was solved when we removed and cleaned the filter which is accessible once the bucket is removed in the front (pull it down and out). Ours was very dirty and it sits between the humidity control dial and what we believe to be a sensor. Once cleaned, the compressor engaged immediately.

A little condensation is not something to worry about. But, a lot can be caused by a dirty or clogged air intake filter. Which can also cause the cooling coils to freeze.

Turn the unit OFF & unplug it, before removing the filter for cleaning.

Also, maintain 12" to 18' of clear air space all around the unit.

If the unit is in an extremely moist or damp environment, 55% is not really a low setting. 35% would be more appropriate for this type of environment.

Hope this helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Check water pan to see if empty. Also check for loose or burnt wiring. Also check for internal resets or safeties

Sounds as if the drain tube from the dehumidifier to the collection bucket may be clogged. Turn the unit of, unplug it and remove the bucket. With a flash light, look up into the rear of the cabinet where the bucket was. You should see a drain hole or short section of tubing. If you can see a clog, carefully remove it. If you can't see one. it may be further up the tube. Use some type of wire that is flexible, but yet firm enough to run up through the tubing or hole. Very very careful when you do this, as you don't want to puncture or damage anything.

The other option, if you have an air compressor is try blowing the clog back through the system, using fairly low pressure.

If all else fails, contact LG Customer Service (800) 243-0000
