The fan never stops running. The dehum. works fine that is the only problem. Is it the way I have it set how can I change that?


Bob, some humidifier fans run a lot, because they are designed to keep the air moving and when the humidity level rises, the compressor turns ON to extract the humidity. If you're operating the unit in a continual mode, it's not unusual for the fan to run almost constantly.Especially, is the humidity extraction level is set at or above 50%. Lowering it to 35% will cause it to extract more humidity and will turn on an off less.

Taking the Confusion Out of Using a Dehumidier


Many consumers are confused about setting the proper levels of humidity on dehumidifier units. And then think something is mechanically wrong with the unit. When in fact, over 70% of the time it operator error. That and a lack of proper routine maintenance are the problem.

The numbers on the LED screen represent the amount of humidity you want to maintain. Not the amount you want to remove. For example: If you set the level at 70%, which is rather high, more than likely the unit may start up momentarily and then shut OFF. That's because the setting is to high. Now, if you set it at 45%, the unit will turn ON and run until either the bucket is full and/or the humidity level has reached 45%.

Here's a good rule of thumb if you use your humidifier year round.

In the Winter you want to maintain a humidity level of 50 to 60%. The moister the air, the more comfortable it will feel. Plus, the humidity helps eliminate static electricity in the air.

Conversely, in the hot, humid Summer months, you want to keep the humidity level as low as possible (35% or less). Also, if you have ceiling fans, using them 24 hours a day, helps to move the air and generate a windchill, which fools your body into thinking it's cooler than what it really is. At the same time, it's saving on energy costs by not having to run your AC as much, because the dehumidifier is removing the humidity.

Just remember, the higher the setting, the higher the humidity level will stay. The lower the setting, the more humidity will be removed and the more comfortable you'll feel in the Summer.

And don't forget Routine Maintenance. Clean the air intake filter regularly. Clean and wipe down the refrigerant coils every 60 days. And don't allow water to remain in the collection bucket to long. As mold can build up in it.

Speaking of which, the water in the bucket, when fresh, is great for watering house plants. Because, when it's fresh, it's distilled water. No chlorine or minerals.

Just bought a dehumidifier in the ground level of a high ranch I am very frustrated because I dump the water every day I waas told to keep the humidity at 45- 50 but it keeps on going up This seems to be a...


It isn't necessary you run it 24 hours a day. You can set it to be on for 2 or 4 hour intervals and then it Turns OFF. However, I am a bit concerned that you have the humidity extraction level set a bit high for a basement application. 50% is more than most basements need to be. Lowering it to 35%, will remove more humidity and eventually will run for shorter periods of time. It takes several days of operation for the dehumidifier to get the humidity under control.

If you have a floor drain in your basement, you can use a hose to daring the water, rather than having to empty the bucket daily (which is not that unusual). See your Owner's Manual on how to connect a 48" length of garden hose to the dehumidifier.

I hope this helped you & thanks for choosing FixYa.

There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1& 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a mechanical unit,
uni, set the control knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. 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 tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor may have failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helped you to troubleshoot & solve the problem.

Generally, most humidifiers work best between 60 -80 degrees . There is a model that is called a Low Temp model, that's designed for low temperatures in basements.

As far as your problem is concerned, there are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a manually
controlled unit, set the Manual Control Knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder

Well, we know the filter was playing a role in it.. Good job on cleaning that. Depending on where you have the humidity extraction level set, the fan could run all the time (It's direct drive. No belt). I suspect if you lower the humidity extraction level to 35%, you will see/hear water collecting in the bucket after about 30 minutes to an hour of operation.

Also, maintain at least 18" of clear air space around the entire unit.

In addition, if you're using this in a basement Ambient air temperature at floor level is between 40 - 60 degrees. dehumidifiers do not work well between those temperatures Unless, you have a Low Temp Unit). This applies mainly to where the air temperature at floor level is colder than at shoulder level
in basement applications . 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 tank of water, will usually resolve this problem.

How do you set it to come on and off automatically


Generally, setting the humidity extraction level to what you want (Remember, the lower the percentage, the more humidity will be extracted) and not operating it in continual run mode will do the trick. Most humidifiers can be set to run in a 2 hour or 4 hour intervals. That means it will run as necessary for 2 or 4 hours and then turn OFF. It will turn back ON again, when the humidity level in the home rises above the setting you have it on.

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