Tip & How-To about Dehumidifiers

Dehumidifier is running but no water is in bucket

If you have a dehumidifier that is not producing any water then you are wondering what you need to do to get this thing to work for you. In some cases you may be able to do something and in other situations there may be nothing that you can do.

If you do not hear the compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.

A few things that can cause this are:

The circuit board relay has gone bad…replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.

The compressor has failed…if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.

If the compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.

If the compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.

If the compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.

If nothing is running, then you may also have a control board failure. Or the humidity sensor or humidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.

Also if nothing is running check the float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.

There are some parts available for a few brands, but with the prices for most of the parts that you can replace running anywhere from 40.00 – 80.00 dollars, replacement parts with labor to install them, makes a repair more then the few hundred dollar cost of many of these dehumidifiers.

As you can see there are quite a few things that can cause your dehumidifier not to work. Systematically go through the list and eliminate things to get to the bottom of the issue causing your problem and then decide if it is worth spending the money to try to fix the old unit. Only you can make that decision.

I have a frigidaire LAD704DUL 70 pint dehumidifier. Last year it worked great. This year, it has not collected any water in the bucket. The motor runs, it is on CO setting but still no water. I have cleaned and replaced the filter. I purchased another brand of dehumidifier and within 1+ days, the new unit collected a full bin of water. What should I do to get the frigidaire working again?

dehumidifier will run but the bucket won't fill. Is there a way to run my model without the bucket? I have a maytag m7dh4582a and do not have my manual. Could their be something else wrong with it?


Hi,
Is it producing water or not??? If no water is being produced, then check out this tip...

Dehumidifier is running but no water is in bucket

If you are making water and it is just going all over the place then, the little spout coming off the bottom of the coil, that runs the water into the bucket is clogged with dirt and you just need to take a small toothpick or knife and work the dirt out of the spout...

Didn't LG produce some bad Humidifiers several years ago and have a recall on not working units? I recall reading this in Consumers Reports. I bought one back then and it has not produced a drop of water although it seems to be opersting normaly!


If has not produced a drop of water for several years, then it's not working properly. But, this may be a case of setting the humidity level to high. In other words, if you set it at 70% or Maximum, that's the humidity level that it will maintain, not remove. To remove humidity, the level must be set low (35% or Minimum).

To test the unit, based on what I just said, place it in the bathroom, set the level as low as possible and turn the shower on medium hot. Do Not turn the bathroom exhaust fan ON. As you leave, close the bathroom door. Return in 15 minutes, turn the shower OFF and check the bucket water collected. If there's any water in it, it's working fine. It was probably a case of the humidity level being set to high.

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