SOURCE: touch control for humidity setting

Yes, the touch pad may defective. But, before you try to replace it, let's try something else first.

Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 15 minutes and plug the unit back in. Turn the Master ON/OFF Switch to ON and set the humidity extraction level where you want it. Hopefully, that 15 minute time out allowed the unit to reset itself and revert back to the original factory settings.

If it didn't you can order replacement parts directly from Haier 877-337-3639 or locate a service center near you.

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

Fan always runs, speed doesnt change (low/high), setting humidity level doesnt impact...is this a control board or circuit board issue?


Verify the humidity reading with another device. Perhaps the humidity sensor is dirty or bad.

Another possibility is the switching device that runs the compressor and fan is shorted. If it's a mechanical relay, the contacts may have welded together, or if it's a solid-state relay, it's got a punch-through or meltdown in a device junction. My guess is it's a mechanical relay since you mention it used to click on and off and now you don't hear that. The relay may be on the control board, or it may be mounted separately - I don't have a photo or diagram of the inside of your model available.

Cannot set humidity level to anything other than 50.


Is it reading the room humidity, rather than showing the set point? Check the manual.

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.

Fedders a7dh45b2a*a-r dehumidifier shuts off before the bucket fills


Actually, it's probably doing what it should. Let me explain: Dehumidifiers run until they have lowered the humidity/moisture level to where you have the humidity extraction level set. At that point, the unit shuts OFF, until senses the humidity level has risen above where you set the level and it turns ON again. That doesn't mean the bucket will always be full when it shuts OFF. It may turn ON & OFF many times before the bucket is full. Watch for the Bucket Full Light to illuminate. That's when the bucket is FULL and needs to be emptied.

Hope this helped you understand how the unit works.

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 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...


The problem is, your trying to raise the humidity level, not lowering. These work in reverse of what you may think. Lower the level (Arrow Down) to 32% and it will continue to run, but will draw more humidity out of the air and will not stop until the water collection bucket is full or the humidity level reaches 32% or you turn it OFF.

When you pushed the Arrow Up Button, it was already on 70%, that's as high as it will go. But that means, you're trying to maintain a 70% humidity level. If it's Summer where you are, I don't think that's what you want.

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

I set the humidity level and it immediately goes back to 90. Do I have to wait until the humidity level that I have set is reached and then it will show that number?


At 90, there's little chance the dehumidifier will remove any humidity. That setting is simply to high.
It may be that the unit needs to reset itself. You can accomplish this by turning the Master ON/OFF Switch to OFF and unplugging the unit for 15 minutes. Then, plug the unit back in and turn the Master ON/OFF switch to ON. Set the humidity extraction level on it's lowest setting. Hopefully, the unit reset itself and will now function as it should.

If that didn't solve the problem, the memory board may need to be replaced.

Hope this helped you to troubleshoot and solve the problem.

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.

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.
