Question about GE AHG40LA Dehumidifier

1 Answer

Humidifier that never shuts off.

I have a GE dehumidifier that is 3-4 years old. It has a digital setting on the front where I set it for How Dry I Want It To Be. The highest humidity setting is 70. I set it to 70 and it never shuts off. We are in the heating season so the furnace is running. The furnace being on usually dries the air in the house. I am sure the humidity in the house is far below 70%. The fan and the compressor run and the coils get cold but I never see it in the OFF state. Have I got a BAD Humidity sensor ? AND where can I get parts for this model # AHG40LCM1 ?

Frigidaire dehumidifier has an error code of EC and does not take in any water. The temp in the basement is a constant 68 degrees.

First, I'm not a Frigidaire tech.
* Check your warranty. Call for service.
* Contact (note Live Chat link);
*** following is for information only ***
* Checking basic problems;
* The humidifier will only run if the "Humidity" (water or moisture in the air) is higher than the current setting on the humidifier. If it's set to maximum dry setting then expect it to run almost 100% of the time. If it is set to a "wet" setting then expect it run only for short periods.
* Colder room temperatures will reduce the frequency of cycles as cold air will hold less moisture than warm air.
* You may note that running a AC unit in the same room as the dehumidifier will give you mixed results as both units will "fight" or work against each other. Humidifier will heat the air as it exits while the AC will cool the air. Best to not run the AC while the dehumidifier is in operation.
* Note that AC do "dehumidify" the air as it passes through. But not as effective as a dedicated dehumidifier.
* Be sure to check the tub and filter (make sure they are seated properly.)
* Contact Frigidaire or your local Appliance store for service.

My GE 50 pt humidifier works great - except it will not let me set the fan speed to low or medium - it runs on high all the time. I am SUPPOSED to be able to set fan to low.... HELP IT"S TOO LOUD ON...

It sounds to me like you have a defective switch. I would recommend that you contact a G.E. dealer with the model and serial number and describe your problem.I can't find the right file right now but I believe thatthis switch is about twenty dollars.Thank you.

I have a kenmore dehumidifier (about 2 years old), and i've found that after i turn the unit on and it is running for 2-3 minutes, it will then shut down even though no water has collected in the tray. any...

My first thought is that there's not enough moisture/humidity in the air, for the setting you have the humidifier set on. The higher the setting or percentage (i.e. 60%) means that the level you want to maintain. Which may be find in the cod winter months. In the Hot summer months, you want as low a level of humidity as possible (i.e. 45%).

My second thought is that the air intake filter and the coolant coils need cleaning, since it has been used in 2 years. It's just sat around gathering dust and spiders.

And finally, the collection bucket, may not be inserted properly and when the unit starts up the vibration dislodges the bucket just enough, so that it's not making contact with the safety switch. Sometimes when this happens, the Full light indicator will come ON, even if the bucket is empty.

Hope this helps you to start troubleshooting the problem. Please let me know.

My GE Dehumidifier fan is working fine, but the bucket is not getting water. I cleaned the filter.

a dehumidifier can only remove water from the air that is humid. have you checked the humidity of the room ti see if it is high or low?

In the winter the average room air is sometimes so dry that one have to add water with a humidifier.
did you check if this is not the case?

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

Humidifier Fan Doesn't Stop

RH at 70 % seems to me a little excessive you really should be working somewhere around 50 to 56% the fan has to move Air through the system.
I would like to know your room Air temp what is the Air temp comming off the system. what are your parameters.


As an example, if you want the Humidity % factor to be 50%, 70% or whatever % you want in the space in question to be, set it at whatever % you want the space to be and the humidifier will work until it reaches that setting. It will then shut down until it determines that the humidity has reached a level that requires dehumidifying again. You can set it to run for 2 hours and it then it will shut down for 2 hours, or you can set it to run for 4 hours and then it will shut down for 4 hours. You just have to decide just how humid the area is that you are dealing with.
Go to; and search for Goldstar Dehumidifiers and you can read comments by others who have purchased this brand. I, myself have one in my celler that has been running for over two years and it has made a world of differance down there.
Good luck. :)
