Re: question on temperature range
Most dehumidifiers run between 42 degrees and up. If you need one for lower temperatures you can buy special ones. If you have cold temperatures in your location the air is usually dryer in the winter so the dehumidifier is not really neaded during that season. The average humidity setting you would want to run it at is 60 Percent. It will keep your basement from becomming damp and also keep it from running nonstop. Good luck and if you found this solution helpful please rate it when you get a chance. Thanks - Tech101

Kathryn, if you are operating it in a basement application, the problem is that air temperature at floor level, is colder than at shoulder level. Dehumidifiers struggle to work at temperatures between 40 & 65 degrees F (Unless they are Low Temp model designed for basement applications). And will ice up at times. Raising the unit up off the floor onto a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water, will usually resolve the problem.
If it's not a basement application, try lowering the humidity extraction level to 35%. In you have an analog unit, turn the control knob to Maximum.
I hope this helps you and thanks for choosing FixYa.
Alan, it may simply be a case of several things, that can easily corrected at home.
1. The Humidity Extraction Level is set to High. Lower it to 32-35%.
2. Air intake filter is dirty or clogged. Remove, inspect the filter and clean if necessary. It it's a Washable Filter, allow it to thoroughly dry before reinstalling it.
3. Obstructed Air Flow. A minimum of 12" to 18" clear air around the entire unit, must be maintained.
4. The ambient air temperature at floor level is between 40 - 60 degrees F. This is particularly true in basement applications. The air temp at floor level is colder than the air temp at shoulder level. Dehumidifiers don't work well in that temperature range (Unless, it's a Low Temp model). Raise the unit up off the floor on to a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full tank of water.
If you troubleshoot the 4 things listed above, it may quickly solve the problem. Please let me know. Thanks.
Gary there are several basic things that may cause the problem you're having. All are easy to troubleshoot and solve:
1. Humidity extraction level is set to HIGH. Lower it to 32 - 35%
2. The air intake filter is dirty or clogged. Remove and clean the filter following the manufacturer's recommendations.
3. Not enough clear air space around the entire unit. Maintain at least 12" of clear air space around the entire unit, while in operation.
4. The ambient air temperature at floor level is between 40 & 60 degrees F. This is usually the case in basement applications. The humidifier strains to extract humidity in that temperature range. Place the unit on a sturdy table or counter that can handle it's weight, plus a full tank of water. The air temperature at chest level is warmer than floor level.
5. The cooling coils on the unit are dirty and need to be cleaned. Use mild soap and warm water to clean the cooling coils, rinse and thoroughly dry. Wipe on a light coating of WD40.
Worse case scenario is that the compressor needs to be recharged with R14 refrigerant gas. This would require the help of a pro to perform. As it requires specialized equipment.
Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
It's 7 years old and has severed you well. Repairs on a unit that old, cold cost as much as a new unit. That's, if the parts are still available for a 7 year old dehumidifier.
As far as advice is concerned ... I agree with you. Since you're using it primarily in a basement. Shop for a low temperature unit. That's one that will function well, between 40 & 60 degrees F. I say this, because the ambient air temperature at floor level in a basement, can be 5 to 8 degrees cooler than the air temperature at chest level. Regular dehumidifiers don't function well at the temperatures I referenced above.
The other features you want to look at is energy efficiency and the square footage or cubic footage it's rated to handle. I would suggest, no matter what you buy, if an extended warranty is available ...buy it. It could be money well spent. Then, only the Routine Maintenance is up to you. Which means, don't misplace your owner's Manual.
When a humidifier is first placed into service depending on the environment you placed it in, it can take up to a week to actually shut off.
Think about this...
Q? Why did you buy the unit in the first place?
Ans. Area you want to use it in is damp.
So the NEW humidifier has to really work hard to remove moisture from everything in the space.
Furiniture, structure to include cement floors and walls. This can take a very very long time initially. If there is a sump pump in the basement the humidifier needs to be placed quite a distance from the sump area. If the structure foundation and walls are allowing water seepage into the basement it may NEVER shut off.
If it does not shut off after several days. Move the unit to a small room upstairs that you can place it in and close the door just to test to see if the unit will cycle on and off. If it cycles on and off in a small room you may want to inspect your basement foundation and check for plumbing problems.
Dehumdifiers work by cooling a coil below the dew point temperature of the ambient air. When this happens frost or water will form on the coil. Most room dehumidifiers work with the room temperature above 65 deg F. It works well when the temperature of the room is 65 deg F or higher. But when the temp is below 65, it won't work because the coil does not reach the dew point.
There are cold temperature dehumidifiers that are designed to work in colder environments such as basements. They can work in a environment as cold as 40 deg F. Check your owners manual to see what type of humidifier you have to see what is the minimum operating temperature for you unit. Hope this helps you.
I believe a dehumidifier is supposed to operate in temps above 60 degrees. Even though your house is warmer than that, the air entering the dehimidifier may be getting into that range due to it being on a basement level etc. This is perfectly normal and is not a malfunction with your humidifier.
Your options are to either place the dehumidifier closer to a heat source in order to keep the air which is entering warmer. (I've even heard of someone placing a light bulb in front the unit during winter to warm the air slightly as it enters). Because the dehumidifier's coils get cold in order for it to collect moisture from the air, if they are freezing, giving the unit a rest for a few hours every few hours may allow the coils to thaw in between and prevent them from reaching freezing temperatures while running. You could use a timer to accomplish this, but you'll want to insure that it's a commercial grade timer in order to handle the electrical draw that the dehumidifier requires.
With that low of a setting it will most likely be kicking in alot more often. Most people run their dehumidifiers between 60-65%. It is a matter of preference. Also some basements hold out moisture more than others. There could be alot of variables affecting this. One thing you need to make sure is that you have the correct placement. Make sure you dont keep it near the sump pump or any other standing water because those areas have more humidity due to the water being there. Also make sure it is not in an area like a laundry room because when your washing machine despenses water it is despensing moisture into the air. I try to keep it at a central location if at all possible and away from areas that have water. If you found this solution helpful please rate it when you get a chance. Thanks - Tech101
