Hot Air Dehumidifier

My danby DDR7009REE is only a month old, It is on, but it cycles between blowing hot air and cool air into the air, I don't remember it doing this before. It shudders quite a bit when the compressor is kicking on, and that's when the hot air comes out. I'm afraid it will overheat. There is water coming through the hose, but the humidity percentage stays about the same. Any solutions? Thanks!

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.

I dropped the water bucket by accident on the dehumidifier, and I have the same problem. Here what I found :
First, remove the water bucket and find the circuit diagram, it is very useful.

E1 code is related to the room humidity sensor, E2 code is related to the room temperature sensor and E3 code is related to the safety thermistor sensor. If you have one of these error code displayed, you will probably have to replace the sensor.

The humidity and temp sensors are located on the same board. To access it, remove the water bucket and you will see the 2 screws holding the front panel. Remove the screws, then gently prayed the front panel. Be careful, there is two plastic clip on the top of the panel and they are really easy to break. The board is located at the top right, under the cover. The safety thermistor is located on a pipe on the right side of the dehumidifier.

SOURCE: Danby ddr7009ree - continuous drain won't work

I have the same Danby unit and the same problem. When you take out the water bucket look inside and find the two holes where the water drips into the bucket. These holes are approximately 5/16" and 3/8" diameter. These holes need to be plugged. Your local hardware store has an assortment of specialized parts boxes. Find the box that contains "corks" of various sizes. They sell for about 20¢ apiece. I bought 5 within that size catagory and two of them worked! Problem solved.

SOURCE: My new Danby dehumidifier never shuts off

This unit is designed with the intention of the fan running all the time. The compressor cycles on and off with demand, however the fan runs continuously to provide constant room circulation.

SOURCE: Hi Fixya:

How often does the unit run? Does the fan run when the unit is suppose to be running(as the fan pulls the air thru the filter). If every thing operates correctly and the filter is in the right location on the unit then all I can say is that you keep a clean house. Personally I only need to clean the air filter on my dehumidifier about once a summer. I wouldn't be overly concerned if it isn't getting very dirty.

Why doesn't the unit cool when the coil temperature is at 40 degrees F.


You asked why your dehumidifier does not cool; it is not the purpose of a dehumidifier to cool the air going through it. It works like an air conditioner except the hot and cold air are not separated out. The cold [evaporator] coil is the first coil in the air stream where humidity [water] from the air collects just like it does on the outside of a glass of ice water. The air then goes through the hot [condenser] coil where it cools the hot refrigerant and reheats the air before being returned to the room.
If you have the patience to follow along the video, it explains the cycle.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.


It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

Danby Dehumidifier DDR7009REE leaking water, bucket not full


Hi there,
The unit may need cleaning. You can contact Danby customer service (1-800-263-2629) to get in contact with a technician.
There may be something clogging the passage to the bucket and the water is finding the path of least resistance.
As well, it is important to remember to clean the filter once a month.

Have classic dehumidifier model#CDR4500E. Can't adjust it automaticaly to come on or shut off. Don't understand the keypad fuctions, booklet to confusing.


Your dehumidifier preset default humidity level of 70%. Which is rather high, if you're using the unit in the hot Summer months. You can override this setting and lower the humidity level in increments to as low as 35%. Which is ideal during hot, humid weather. The Air Down button lowers the humidity level.Once the level is set, the unit will cycle ON and OFF as necessary, to maintain the level of humidity.

I have looked at the Owners Manual for you unit, and it's very thorough. But, I can understand, if you're not familiar with how the units work, it could be confusing. Page 5, is very informative on how to operate the unit, as far as setting humidity levels, which is what's important. If the operation of the unit continues to be a problem for you, contact Danby Customer Support 1-800-263-2629 and they can walk you through the procedures, while on the phone with them.

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

My Danby DDR586R dehumidifier shouts hot air, it was shooting cool air before, what can the problem be?


Here is Danby's official response to a similar question on their FAQ page for Dehumidifiers:
https://www.danby.com/faqs.php?cat=12

Q) When the dehumidifier is operating, is it normal for the expelled air to be quite warm? We find that the dehumidifier is warming up the room noticeably (a finished basement).

A) 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 degree or two.

The dehumidifier is blow cold air


Is it collecting water? The air coming out the back top half should be cool/warm. It will be a little warmer at the bottom near the compressor.

Again, if your model is one that can be used in cooler temps so as not to ice up, the heat prevents this.
