I cannot change the set point on my humidity control. It is at 70%. If I press the up arrow i get 2 beeps and no change. When I press the down arrow there is no response at all. Is there some sort of locking feature? I borrowed teh unit from my neighbor and he has no clue either. The fan and condenser are both running but no water is being produced.

If your machine is equipped with a humidistat it could be faulty and not sensing the humidity level accurately.

Prt of the problem may be a dirty or clogged air intake filter.

Turn the unit OFF and unplug, it before removing the filter to check and clean it.
You can ether vacuum it or if it's really dirty & clogged, wash it in warm water and mild dish washing liquid. Rinse thoroughly, shake off access water and allow it to dry completely, before reinstalling it.
Never operate the unit without the filter in place. As this could damage the unit.

Plug the unit back in and turn it ON. Try lowering the humidity extraction level now, using the arrow down button. For a very damp, humid basement application 35% is a good setting to start with for several days.

Hope this helped you and thanks for choosing FixYa.

It is not abnormal for ON to show up when you first push the arrow up or arrow down button. If you want to lower the humidity press the arrow down button again, once the ON lights up. The lower you take the percentage the more humidity will be removed.

Since your Danby, discontinued model has several features that require a picture to understand how to set the controls, as well as how to use the remote control. I have provided a link to your Owner's Manual (in case you have misplaced yours) that you can download and print, for future reference.

The one thing I would suggest, that you keep in mind is that the lower the percentage of humidity extraction you set it on, the more humidity it will absorb. Which is what you want in the summer. Do Not press and hold the arrow down button. Press it down in increments, until you reach the level you desire.

Hope this helps you.

Let's start from the beginning. Turn the Master ON/OFF Switch to OFF. Unplug the unit for 5 minutes. Then plug the unit back end, and turn the Master ON/OFF Switch to ON. Now, lower the the humidity extraction level to 40%, by using the Arrow Down Button. You will need to lower it by pushing the button for each % setting. DO NOT push and hold the Arrow Down Button.

Doing the above should solve the problem.

SETTING THE MACHINE TO TURN ON
1. Make sure the dehumidifier is plugged in but turned off.
2. Press the button with the clock symbol below it.
3. Press the up arrow to set how many hours until you want the machine to turn ON. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours.
4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity.
5. After the above steps are completed the dehumidifier will turn ON in the number of hours that you have set (programmed).

SETTING THE MACHINE TO TURN OFF
1. Make sure the dehumidifier is plugged in and running. You should hear the fan blowing for sure.
2. Press the button with the clock symbol below it.
3. Press the up arrow to set how many hours until you want the machine to turn OFF. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours.
4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity.
5. After the above steps are completed the dehumidifier will turn OFF in the number of hours that you have set (programmed).

I don't think it's a thermistor problem, as previous respondents have suggested. I have one of these units. The control panel has been nothing but trouble. The Power button works, but the Fan Speed button is stuck on High. The Humidity Up/Down buttons only work sporadically. Sometimes they work if I keep punching them. There doesn't seem to be any rhyme or reason as to when they work and when they don't. I think they're just cheap parts that have failed prematurely.

When you first turn on the unit it is set to 40% humidity which is the lowest the unit will accept. You can only move the up arrow from that point. The 63 you are seeing is the actual humidity. If you want 50% youo need to press up arrow till 50 is displayed. The manual for this unit is terrible. Just leave it as it is and it will attempt to bring it down to 40%. 30 to 50 is the recommended humidity range.

the control board is a very simple design and it is to signal and switch options like fan speed, power on/off, humidity up/down and sets the on/off run time. Like above the board does collect dust,but the true problem runs deeper.

My unit was stuck in run mode with the fan speed, humidity and run timmer non functioning. the unit worked and the power switch turned it on and off. The display said ON

I removed the front cover (two screws) and slight pressure on the side of the cover to remove it. This exposes the control board. The control board can be removed by removing the 6 screws on the board. the cable can then be removed by pulling out the multi-pin ribbon cable.

I diagnosed that only two of the 5 push button switched were functioning. There was also dust and mold on the board. This board is poorly protected from the moist air entering the unit and the constand moisture causes corrosion on the board, the switched seem to be the weak link.

By using a multi meter I noted that only the power switch and the humidity down button were making contact when pressed. Now it all came together. I could turn it on and off. and if you press the humidity down button to the lowers setting (ON) means run all the time.

I used a elecronic contact cleaner and sprayed it into each of the switches. I wiggled it around and blew it out with canned air. It took a few wiggles and blasts but all switched then made contact. I the board back on and tested all functions and it was like new. The contact cleaner should keep it protected for a while. The non functioning of the switches works both ways. They can stick on also. This would explain most of the other control problems. These switched are common and can be picked up at Radio Shack. On a do-it-yourself bananna scale it was a 2 for me, but I had the tools and the spray. I am not sure what sears gets for the PC control board,but this is the issue and if they were to address this the unit complaints would drop greatly.
