How do you set on and off auto


See page 7 on the user manual to set the humidity level and the unit will then operate within the set humidity range. You can also set the timer to make it shut off automatically after a specific time. You may also need to install the continuous drain feature if you do not want to empty the water tank repeatedly.

Is there any way to run automatically. . . where when it reaches humid per cent it shuts off? Can you rig to run for x hrs. per day and then shut off and restart the next day?


Norman, once the unit reaches the extraction level you have it set for, the unit will turn OFF automatically. However, depending on the humidity level in your home, it may take several cycles of running and emptying the bucket until it reached. After that, it should turn OFF, once the level is reached. Then when the humidity level rises above the setting it's on, it will start up again.

Since your unit is a Manually Controlled unit, there's no safe way to "rig' it to run on with a timer. The plug in wall timers are not rated high enough to handle the load of the dehumidifiers operation. Trying to use one, would fry the timer and possibly the dehumidifier.

If you want all the features you mentioned, you will need to purchase a new electronically controlled dehumidifier.

The dehumidifier shut off automatically but will not come back on. Model M7DH45B2A


If the unit shut off automatically, because it had reached the humidity extraction level you had it set on. It won't turn back ON again, until the humidity level rises above the setting you have it on. Lowering the humidity extraction level to 32 -35%, should make it start up again and cycle like it should. If your unit does not have an LED Screen, set the manual control on Maximum.Be sure the bucket is not full and the air intake filter is clean.

Hope this helped you to troubleshoot and solve the problem.

My LG Humidifier turns on and seems to run fine for a few minutes then the present humidity % starts going up and up all the way to high then the whole thing shuts down. Of course it does not run long...


Chef, you need to turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 15 minutes. While you're waiting, remove the air intake filter and clean it, if necessary. After the 15 minutes has elapsed, plug the unit in, turn the Master ON/OFF Switch to ON and set the control to Manual Operation. Lower the humidity extraction level to 32% or 35% and allow the unit to run in that mode, rather than automatic. This will give you a good indication if moisture is being extracted or not.

If it is working as it should, you can leave it in manual timed mode (normally 2 or 4 hour segments). This way, cycle On and OFF as necessary, based on any rise in humidity above 35%.

I hope this helped you solve the problem. Please let me know. Thank you.

How do you set it to come on and off automatically


Generally, setting the humidity extraction level to what you want (Remember, the lower the percentage, the more humidity will be extracted) and not operating it in continual run mode will do the trick. Most humidifiers can be set to run in a 2 hour or 4 hour intervals. That means it will run as necessary for 2 or 4 hours and then turn OFF. It will turn back ON again, when the humidity level in the home rises above the setting you have it on.

Hope this helped you. 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.

I have a Goldstar Dehumidifier, model # GHD30y7 (S No 611TADR26946). It has worked well for a couple seasons. This season it will not stay running. It cycles on but shuts off after a couple minutes. I have...


Kreston, check the humidity level you have it set on. It may be that there is not enough humidity in the air for what you have it set on and it automatically shuts OFF.

Keep in mind, whatever level (percentage) you have it set on, is what it will maintain, not remove.
For example - if you have it set on 65%, that's pretty high level of moisture/humidity. But, it's not how much it's going to remove from the household air. Unless, the humidity level rises above 65%. Then it will only remove enough to maintain 65%.

If you want to remove humidity/moisture, you have to lower the setting below 45 to 50%, Try that and I think you'll meet with success.

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

Our dehumidifier turns on for only a few seconds, then shuts off.


Wendy, it's probably because the humidity level on the unit is set higher than the humidity level in the house. Keep in mind, the humidity level you set the control to, is not the amount extracted from the air. It's the level you want it to maintain. The higher the percentage level, the more humidity stays in the house. The lower the percentage level, the more humidity it removes, until the lower humidity level is reached. Then the humidifier will automatically shut OFF and/or the unit shuts OFF, because the bucket is full. Once it's emptied and replaced, if the unit needs to continue to extract humidity, it will start running again.

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

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.

User Manual has no guidelines.


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.
