Returned the first one to Home Depot, the second dehumidifier runs but does not extract any water as well, stays at 80%.


dehumidifiers need humidity to work so check that the a humidity of the room area has a readable humidity level for it to work
if the humidity is over 50% and it is not working then maybe the ac part is not working properly

What is the proper setting for Danby R410A?


R410A is refrigerant gas. I think you wanted to know, what humidity extraction level the controls should be set on. If it is really hot and humid in your area, set the humidity extraction level between 35 & 40%. If you have a mechanical control, turn the knob to Maximum.

Hope this helped you, Bradleyjo. Thanks for choosing FixYa.

What is the proper setting for the Temp &Humidity?


Set the temp level at whatever point your home's temperature is now. Lower the humidity level to 35%. If you don't have an LED screen on your unit, set the manual control to maximum.This way, you will extract the maximum amount of humidity and make your home more comfortable.

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

I have a Danby Silhouette and the fan works but the dehumidifier doesnt.


Bryan, it may imply be a case of the humidity extraction level being set to high. Lower the level to 35% and see what happens. As far as the fan running is concerned. Most dehumidifiers are designed for the fan to run, even if the compressor doesn't turn ON. It's designed to keep the air circulating and if the humidity rises above the setting you have it on, the humidity sensor will pick up this change and turn the compressor ON.

Also, remove the air intake filter to see if it's clogged and needs cleaning. Maintain at least a minimum of 12" of free air space all around the dehumidifier. Poor air circulation will prevent the unit from working properly. As will, to low an ambient air tempeature. Most unit struggle to work at temperature between 40 & 60 degrees F.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

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.

Unit runs but doesn't collect water and there is a lot of water in the basement. Have had dehumidifier for two weeks and was working well before.


Keep in mind, that a dehumidifier only draws humidity from the air, if the level of humidity is higher than what the controls are set on. For instance, if you have the dehumidifier set on 65 to 70%, that's a high level of humidity to maintain in a house. If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. Also, it's not uncommon on some dehumidifiers for the fan to almost run constantly. It's designed to keep the air moving, in a effort to detect when the humidity level rises.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filter no is the time to check and clean it. And while your at it, clean the cooling coils too. Since it sounds like this unit has been working hard for 2 weeks.

The easiest and best way to test a dehumidifier at home, to see if it's working properly. Is to place it in the bathroom and turn the shower ON and don't operate the bathroom's exhaust fan. Set the humidity level low (45%), turn the unit ON and close the door when you leave. Wait 15 to 25 minutes and check the water collection bucket. If there's water in it, it's working as it should.

For more information on the proper operation of a dehumidifier, go to the Tips section of Fixya and look up "Taking the confusion out operating a dehumidifier".

Hope all this helps you troubleshoot and solve the problem. Please let me know. Thanks.

Of our three 54501 Kenmore dehumidifiers, none produced water after two - three weeks. They run but no humidity is drawn out of the air.

If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. I find it uncanny, that all 3 units are not collecting any water. So, it may simply be the case, that the humidity level on each unit is improperly set.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filters on a regular basis, not is the time to do so. And while your at it, clean the cooling coils too.

Settings


As an example, if you want the Humidity % factor to be 50%, 70% or whatever % you want in the space in question to be, set it at whatever % you want the space to be and the humidifier will work until it reaches that setting. It will then shut down until it determines that the humidity has reached a level that requires dehumidifying again. You can set it to run for 2 hours and it then it will shut down for 2 hours, or you can set it to run for 4 hours and then it will shut down for 4 hours. You just have to decide just how humid the area is that you are dealing with.
Go to; www.shopping.com and search for Goldstar Dehumidifiers and you can read comments by others who have purchased this brand. I, myself have one in my celler that has been running for over two years and it has made a world of differance down there.
Good luck. :)
