Danby Dehumidifiers Frequently Asked Questions


What humidity level (RH) should my dehumidifier be set to?

Depending on your personal preference and to fight against mold and dust mites, Relative Humidity level is best between 40-50%.

My room air is measuring slightly less than my dehumidifier setting. Is something wrong?

Dehumidifiers reduce mold allergiesThe margin of error of the humidity sensor can be +/- 5% RH. Although it should stop at the level you have set it, it can be a few degrees above or below your manual setting before the compressor turns on/off automatically.

What if there is an odd smell coming from my Danby dehumidifier?

A dehumidifier by itself will not produce any form of smell. Usually any smell that emits from the unit will be something that is recycled from the room itself.

What is relative humidity?

Relative humidity is a percentage showing how much water vapor is currently trapped in the air relative to the maximum amount of water vapor the air can hold at a given temperature. Imagine that you have a glass of water and begin to stir sugar into the water. When you get to point where you have put a full cup of sugar in the glass, you notice that the sugar no longer dissolves and that it begins accumulating at the bottom. At this point, the water is saturated with sugar and will hold no more. At the point where you have put only 1/2 a cup of sugar in the water, you are at 50% of the maximum the water can hold at the current temperature. Now, think of the air in your home as that glass of water and the moisture vapor in the air as the sugar. Your relative humidity level is the ratio of the current amount of water vapor in the air relative to the maximum amount of water vapor it will hold at a given temperature.

Why isn't water draining into the bucket?

Danby 70 Pint DehumidifierThere may be an obstruction in the drain pan above the bucket, check to make sure no obstruction has occurred.

My Danby unit will not operate. What should I do?

Check power cord connection. Check electrical outlet for a blown fuse. Check if water tank is full (empty). Check water tank is properly installed.

My Danby's water removal capacity seems to be low?

Check to see if the air filter is dirty and/or blocked. The room temperature might be too low, (below 15.5° C/ 60° F). Check to make sure that there is no obstruction to the unit that might be causing poor air flow circulation.

My dehumidifier is not collecting water?

If the room air has a lower relative humidity than the set point, then there is no water in the bucket because there is not enough humidity in the air to be condensed and extracted. During drier, winter months there is likely not enough humidity in the air to have water collect in the bucket. A Danby dehumidifier will generally only extract humidity out of warm air since the condensation process occurs only by lowering the air temperature with refrigerant. If you are running a dehumidifier in your basement in the winter, the room may be damp but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.

Should the unit shut off when the house reaches my set Relative Humidity?

All of Danby's dehumidifiers are programmed so that the compressor will cycle (i.e. shut off) when the set air RH% is reached. However, the fan will run continuously.

What is Porting?

Porting your DehumidifierPorting is the process of using an exterior drain line to continuously drain your dehumidifier. As mentioned above, most of the dehumidifiers we offer come with a port where a plastic or rubber hose can be attached to drain the water collected from the unit. A suitable type and length of hose can be purchased from your local hardware store. Porting is a fairly simple process and works best when gravity is on your side. The dehumidifier needs to be placed in a higher position than the receptacle where you want the water to drain into. If this is not possible due to a grade or a lack of a nearby drain, you can still port your dehumidifier, but you will require a condensate pump to push the water longer distance.

Do I need a condensate pump?

Condensate Pumps for DehumidifiersA condensate pump is a simple pump device that pushes fluids much in the same way a sump pump works. The only difference is a condensate pump is built mainly for the purpose of moving moisture removed by dehumidification. This small pump attaches to the dehumidifier the same as if you were simply porting it. The hose runs from the dehumidifier to the condensate pump and then a separate line runs from the pump to your drain. A condensate pump allows for continuous drainage of your dehumidifier and eliminates the hassle of emptying a heavy water bucket. This is a simple and inexpensive solution to use when there are no drain lines readily available for your dehumidifier, or when gravity is working against you. The condensate pump pictured is for use with home dehumidifiers.

When my Danby is running, the exhaust air is quite warm...is this normal?

The warm air that is being expelled from your dehumidifier is normal. When the unit is dehumidifying the compressor is working which causes the compressor to become quite hot. In order to avoid having the compressor overheat, air is drawn by the compressor at a rapid rate and the heat is then transferred to the air which must be expelled from the unit. The warm air will stop shortly after the unit has reached the desired humidity. This warm air should not change your room temperature by more than a couple degrees unless the space is very small.

What do I do when my dehumidifier stops working?

Your first step would be to reference the user manual to check any simple troubleshooting measures. While a dehumidifier is a simple appliance, it does have several things that could go wrong with it. From sensors and a humidistat to heating and cooling coils, there are several aspects of a dehumidifier that could be malfunctioning. Some have filters that need to be changed. Other times, a certain feature has stopped working such as a faulty humidistat causing the dehumidifier to run constantly. In most instances you will want to locate your closest servicing dealer. Contact the manufacturer and they can point you in the right direction. If the dehumidifier is under warranty the repairs likely will cost little if anything at all. If your unit is beyond its warranty, you may find it less expensive to purchase a new dehumidifier rather than repair your current one. If this is the case, contact the manufacturer or a local organization about recycling options. As with all of our products should you have a problem with a Danby dehumidifier you purchased from us at AchooAllergy.com, contact customer service, toll-free, at 1-800-339-7123 for an exchange of a defective or malfunctioning dehumidifier.

Should I keep the box?

Keep your dehumidifier box?Should a dehumidifier you purchase from us encounter problems due to no fault of your own within 60 days of purchase, you can contact customer service to obtain a Return Authorization number and exchange the unit. For this reason, we recommend you keep the box your dehumidifier arrived in for at least 60 days. If you have the storage space you may want to keep the box for as long as the manufacturers warranty time period.

How do I maintain my dehumidifier?

There is very little regular maintenance required for dehumidifiers. For most models, you simply unpack them and plug them in. The primary maintenance with these units is disposing of the water collected in the drip tanks. Most come with convenient built in handles, so after you slide the bucket out of the unit you can easily carry it outside or to your drain to dump.

A more convenient option is to port your dehumidifier. Nearly all of these units come with a small port toward the bottom on the unit. From this port you run a small hose to an existing drain. Some people find it best to tie this drain line into your existing HVAC drain line (for moisture produced by your air conditioner) or possibly to a basement drain. From time to time you may want to check the tank and make sure it is clean and check the drain line (if ported) for blockage. If the unit has a removable cover you should check and clean the condensing coils annually.

I am trying to direct drain my Danby, but the water keeps going into the bucket?

Ensure that you are using a hose no longer than five feet. Also ensure that the hose is draining down into a drain in the floor. Please note: The direct drain feature relies on gravity to move the water through the hose. The only other direct drain option is through the use of a condensate pump.

Why does the fan in my Danby dehumidifier run all the time?

For past versions of the Danby Premiere, the fan would run all the time. This was to keep air circulating in the space, but new for this year, each 50 and 70 pint Premiere features a fan that will actually shut off a few minutes after the compressor stops. This does a couple things. First, it cuts down on noise created by the machine since the fan does not operate all the time. Second, it should help to reduce the buildup of heat in the room. Since it often takes a little while for the motor to cool, as the fan operates, it blow dried air over the motor which picks up heat and is exhausted into the room. Since the fan no longer operates all the time, it should also help with heat. Lastly, it may cut power consumption. This is going to be a very minimal change though since the fan itself uses very little power, and these dehumidifiers, as Energy Star compliant appliances, use little to begin with. Premiere models made prior to 2014, though, will have a fan that operates all the time.

Can I safely recycle the water my dehumidifier produces?

recycle the water in your dehumidifierThis is a "yes, but" answer. If you are not porting water away from your dehumidifier, there are many things you can do with the condensate that your Danby dehumidifier produces. Keep in mind that the water produced by air conditioners and dehumidifiers is not meant for human consumption. While it will often initially be free of pathogens, it can stagnate quickly. If the tank is not kept clean, the water could become contaminated if fungi or other organisms begin to grow in your tank. What also makes it unfit for human consumption is that dehumidifier water often lacks the mineral and inorganic substances that make water potable. This also means you should not use the water to fill your pet's water dish.

The best use is for watering your plants or gardens. For those who want to conserve water or in places where water may be at a premium, you can use your dehumidifier water to water your indoor plants or use it outside for a vegetable garden, flowers, or other landscaping you may have. While you cannot drink the water, it still can be put to good use.

Depending on the environment this same advice will hold true for our commercial / industrial dehumidifiers. The exception would be while using a dehumidifier in an environment where there is toxic and harmful chemicals in the air. In these instances the condensate produced may contain these substances and should be handled accordingly.

What does the P1 indicator on my Danby mean?

P1 is part of a normal function of your dehumidifier. When your compressor is working frost can form on the cold evaporator coils. When there is enough frost on the coils the unit will go into a P1 de-icing program. This de-icing cycle will last anywhere from 15-45 minutes. Once complete it will automatically resume normal function. The cooler the room the more often this function will turn on.

What are other ways I can reduce moisture in my home?

There are several other things you can do, in conjunction with the use of a Danby dehumidifier, to help reduce the level of humidity in your home. First, make sure there are no leaks or seepage in and around your home. Improper landscaping, leaking pipes, faulty gutters and clogged drains can all increase the amount of water and moisture in and around your home. Next, use your dryer. Some of us like to allow certain articles of clothing to air dry for fear of shrinkage in the dryer. By allowing laundry to air dry in your home, you are increasing the overall humidity levels.

Always remember to use exhaust fans whenever possible. While using the dryer helps, inspect the vent to make sure it is actually vented to the exterior of your home and inspect the hose for cracks or leaks. In the bathroom and kitchen exhaust fans can quickly remove excess moisture out of your home. By keeping doors open in your home you can allow air to circulate from room to room. By allowing heat to circulate, you can bring warm air to colder places where moisture is likely to condense. Lastly, it always helps to air our your home from time to time.
