Question about Dehumidifiers

How do I clean the coils on my Hampton Bay Dehumidifier?

Humidifier is running but not extracting water. Could the problem be in the coils? I cleaned the filter. The unit is 10 years old. Has it seen better days? Any help would be appreciated.

The problem is probably due to dirty or clogged coils. Cleaning the coils to a dehumidifier is similar to cleaning the coils on an air conditioner. It really depends on how dirty the coils are. If it is not too dirty you can use a shop vacuum with a brush attachment. If it is really dirty you will have to use a non acidic hvac coil cleaner or you can use a household cleaner like Simple Green that has been diluted 1:1 with water and placed in a spray bottle. Spray the solution on and let it sit for 5-10 minutes. Make sure you unplug the unit before doing anything. If you use Simple Green make sure you spray it down with clean water. If you use an hvac type coil cleaner some do not require rinsing. Follow the directions on the product exactly. You might have to use a brush or even a putty knife if the coil is totally clogged. Be careful you do not damage the coil. Good luck!

How do I clean the dehumidifier?


A dehumidifier works just the way an air conditioner works but in a reverse manner. If you encounter a problem with your dehumidifier then it would be repaired the same way you would repair an air conditioner. As such a dehumidifier does not require much cleaning apart from changing the filter. When the filter and coils of the dehumidifier are choked with dirt, it may not pull out moisture from the air properly. The efficiency of the dehumidifier gets decreased and the only solution is, to clean it thoroughly. In order to assist you with the cleaning procedure of a dehumidifier, following are a few tips:
  1. Remove the water tank/container and clean it after draining the water. Depending on the usage the container must be cleaned regularly.


  2. Cleaning or changing the filter is also important for the main function of ensuring a healthy atmosphere is performed by the filter. Mix some bleach with warm soapy and clean the filter. It will help to get rid of the bacteria, molds and mildew.


  3. Use a vacuum cleaner to clean the evaporative coil/hot coil. Scrub off the dirt using a brush but make sure that you don’t bend the fins while cleaning.


  4. Clean the condenser or the cold coil the same way. If the humidifier is working in a room where the temperature is below 60 degrees Fahrenheit then check the coils whether it is not icing up.


  5. See to it whether the fins are bent or not, if they are bent then straighten them out using a fin comb otherwise it might obstruct the effective working of the dehumidifier.


  6. And yes do not forget to clean the fan blades and other parts of the dehumidifier.


  7. Keeping in mind the humidity level of your room, sets the humidistat of the dehumidifier as keeping it too low or too high may only make the dehumidifier to run longer than necessary.


Also before you start with the work of cleaning the dehumidifier, make sure that it has been unplugged.

Dehumidifier is running but, no water is being extracted from the air.


Hi,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.

Dehumidifier headaches!


There are three things that must be working to extract water. The 'coil' (a finned metal part that allows air passage) if it's filled with dust and obstructions, no air can move...no water. There is a blower motor that mus move the air. If it is seized up an not blowing air...very little or no water. The compressor uses condensation from the air moving across its coils (like the moisture than forms on a cold glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.

My kenmore 50 pint dehumidifier 54501 runs but it does not taking in water


You need to determine what's "running". Here's why: There are three things that must be working to extract water. The 'coil' (a finned metal part that needs air to flow across its surface) may be filled with dust and obstructions, so no air can move...then no water. There is a blower motor that must move the air. If it is seized up and not blowing air...very little or no water. The compressor creates condensation from air moving across the coil (like the moisture than forms on an ice filled glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.

My Hampton Bay HB30 dehumidifier is still running, but no longer produces any water. The fan is running, you can feel the air moving. In addition, it will not turn off with the switch.


The filter and coils might be clogged with dirt. Turn of the unit and unplug it. Look at the filter and coils to see if they need cleaning.
