Kenmore Dehumidifier won't turn on

My old dehumidifier came with the house and it's never worked right so I just got it fixed -- supposedly. I took it to the Sears repair shop. All I can tell you is that I expected to plug it in and turn the humidistat to constant and have something happen. Nothing is happening. I'm completely untechnical and I know there could be some basic thing I'm not doing. (I don't have the instruction book.) Help!

The following statement is a parameter for all dehumidifiers and some of the control issues may vary, but the theory is the same.

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.

Replace the ON rotory switch on control panel part # 6601A3000EA, from LG, $15 shipping included from LG. This worked for me!!

I replaced the humidity sensor assembly first, this did not help the promblem of not turning on.

My dehumidifier is not working. The control panel lights-up, but its stuck on 70% humidity and won't adjust down. I took it apart and noticed burnt marks next to the circuit that controls the humidity....


I'd say you're right on target. In which case, although the unit was manufactured my Whirlpool for Sears under their house brand, Kenmore. You can find the part(s) online at Sears Parts Central
http://www.searspartsdirect.com/partsdirect/index.action . If you can do the replacement yourself, you'll really save $$ on labor.

Hope this helped you. Please let me know. Thanks.

Our dehumidifier is no longer pulling moisture out of the air. I took the back off and the fan is still running. So motor or condenser? And is it worth fixing? The machine is approximately 6 years old.


Hi,


There are many reasons why a dehumidifier will not work or collect water.


Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier

My dehumidifier runs but lets out warm air. Is there anyway I can repair myself ? What could be the problem? Help,,, Thanks


The dehumidifier is supposed to be releasing warm air. In order for the built-in refrigerator to lower the coolant's temperature, heat must be removed from it. Thus, that removed heat flows out of the unit. If it's a problem, I would suggest having a fan nearby, or perhaps you could put the dehumidifier in a cooler part of the house. (In case you're curious, try looking for any vents near your refrigerator or freezer, and you'll see what I mean.)

there is a freeze stat on the unit it connects to the evaporater coils it is suppose to shut of the compressor unit when it senses the temp is at freezing the idea is that the unit condenses moisture out of the air like your air conditioner for your house or car this part is dirty or malfunctionong

Dehumidifier only two years old now doesn't extract water from air since I just started it up again for the summer.


Problem is that you bought a dehumidifier made by the Korean/Chinese manufacturer LG.
Search the web and you will find that you are just one of many whose dehumidifier worked the first year but now draws no water out of the air even though it makes all the right fan and compressor noises.
Most common problem is that all the Freon refrigerant escaped, apparently because the copper tubing cracked and leaked. Penguins beware, there goes the Ozone Hole!
It cost me $14 and an afternoon of investigation and testing of my LG 504EL dehumidifier to figure this out. The fix-it web site "Just Answers" said that it wasn't worth fixing after I described all the symptoms. Tomorrow I will go to the local LG fix-it shop and try to get a replacement to tide me over until I can find a reliable dehumidifier.
Sadly, last Fall I took my 25 year old Westinghouse (made in America) dehumidifier to the dump. Even though it needed me to tune it up every year or two, at least I could fix it and it kept on working for 25 years.
Good luck!

Hopper not seated right


I had the same problem with my Kenmore dehumidifier. The bucket couldn't be properly seated because the plastic cracked slightly at the site where the bucket normally is held. Because of this, the button that it is supposed to be pushed in to keep the dehumidifier running wasn't pushed in all the way. A friend has a Kenmore with the exact same bucket- tried hers, and it works perfectly.

The problem I have now is that I can't find the bucket for sale.

Dehumidifier switches on and off continuously


Patty - Is it possible that the dehumidifier is cycling... meaning there is not enough moisture in the air for it to run constantly.
