Humidifier Runs but no water collected

The humidifier will run when turned on but there is no water collection after many hours. The filter has been checked and cleaned and there is airflow (air is blowing out the top vent). I dont' know what areas I should be checking on. Thanks for your help. Regards, Steve

    I also have the same problem...the compressor runs but very little or no moisture collects in the bucket. If the problem is freon, what is the least expensive option? Thanks!

Are you talking about a dehumidifier or a humidifier. If you are talking about a dehumidifier, it works by blowing air across a cooling coil causing condensation and the water will drip and pool. The cooling is caused by a compressor working like refrigerator, but using the effect to dehumidify. To check if the cooling coil is working there will be a metal can like in it with tubes in and out. One of the tubes should be warm(input) and the other tube should be cold, if not your compressor is not working. If freezing up, low freon. Check to see if the compressor shuts off very quickly, that would be too much freon. This is not user servicable. Now a humidifier works several different ways. One way is a fan with cloth belts rolling through water using evaporation to humidify. Another way is for a circular fan like on a motor to turn. It has a hollow piece into the water. It picks up water and then through centrifugal force aerates. One way is for a sonic humidifier. All the types have a problem with eventual calcification or mineral build up in the water handling paths. Lime-away or Concentrated Lemon Juice will dissolve this. The lemon juice is the most fun. It will turn your toilet bowl white and also remove rust stains from laundry...

No water is collecting on 2 year old lg humidifier


If when you turn your dehumidifier on the compressor runs then you should get moisture. Dehumidifiers work on the same principal as refrigeration. There is a bad control switch or the compressor start relay or capacitor is defective. If compressor runs and there is no effect then that is another problem. The filter should come out the front where the air goes in front and the filter should be washed by hand in warm degrease detergent water, dry and replace. If the disposable type filter I will help you contact LG.Thanks, Sea Breeze
