The compressor only turn on once (GE AHH40LHG1)

If it is very cold some of these consumer units will not turn on the compressor. If the unit suddenly stopped working and the temperature is room temperature I would guess a refrigeration issue- either a leak or bad compressor. Make sure the "full bucket" indicator light is not on- the condensate bin may not be plugged into the unit properly.

Part of the problem may be that you have the humidity level set to high. The fan runs constantly to move the air around. When the unit senses a humidity level higher than what you have it set for, the compressor turns ON. Once it's ON, if the humidity level is short lived, it turns OFF.

Try setting the humidity level to the lowest possible setting. Usually, that 45%. If the humidity level in you home is higher than that, the compressor should turn ON and run until either the bucket is full or the humidity level reaches 45%. If this doesn't solve the problem, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 12-15 minutes. Plug the unit bakc in, turn the Master ON/OFF Switch to ON and set the humidity level at it's lowest setting. Allow the unit to run until it cuts OFF and check the bucket for water. Hopefully that 12-15 minute time out allowed the unit to reset itself.

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

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

Hi,
The compressor has gone bad and will not start... what you he3ar is the compressor trying to start....it will probably cost you more to replace that compressor then buying a new unit...

yes
whenever the compreesor is running you ned the fan to run for two reasons
1 to cool the compressor
2 to sling the condensate on to the evap to keep that from building up frost

Your unit is probably operating in defrost mode. When you use a dehumidifier in a cold room, the condensing coils can freeze water. The unit senses this and thus stops the compressor until the water frozen on the coils melts. Then it resumes its cycle. This is a problem you will have during the winter months. It makes the operation of the unit inefficient, but this is otherwise normal behavior.

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.

You may also want to check the coils and make sure they do not have dirt or dust on them. If they are clean you may have an issue with the refrigerant level which will cause the coils not to cool properly. For that you will want to contact LG. There could be an issue with the compressor also. LG backs alot of their models with a 5 year warranty. Contact them and let them know about your issue. Make sure you still have your reciept. Here is their contact number:

What is the temperature in the space where you are operating thsi dehumidifier? When you first start a refrigerating system some refrigerant may have condensed into the compressor oil. When the compressor starts the pressure in it drops rapidly. The oil boils and some passes through the compressor valves. After a few minutes of operation this condition normally corrects itself.

By condenser I assume you mean the compressor is running. Is there ice forming on the front coil?
