Dehumid....ad70usso....runs all the time auto settings don't seem to working collects fine ..but won't turn off when air is dry thanks

The switch may not be the problem. However, a dirty or clogged air intake filter or the humidity extraction level set to high could be.

Turn the unit OFF & unplug it.
Remove and clean the air intake filter thoroughly. Be sure the filter is completely dry, before reinstalling. Never operate the unit without the filter in place.

After the filter is dry, reinstall it, plug the unit and turn it ON. Lower the humidity extraction level to 35%. If you have an analog unit (No LED screen) set the humidity extraction knob on Maximum.

And finally, be sure that the water collection bucket is installed properly and is not vibrating loose when the unit runs. It should fit squarely into it's holder, making contact with the bucket safety removal switch on the back wall of the bucket holder. When installed properly, it should not tilt down at the bottom of the bucket.

All of the above should solve the problem and you won't need to purchase a new switch. But, in the unlikely event, that you will have to. You will need to furnish the Brand Name of the unit and the Correct Model Number. As, they are not all the same.

There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you troubleshoot & solve the problem. Thanks for choosing FixYa.

Does it have a filter?

also:

"
It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises."

Before you have it repaired, there are several things you can troubleshoot and solve yourself, that won't require any repairs.

1. The humidity extraction level may be set to High. Lower it to 32 - 35%.

2. The air intake filter is dirty or clogged. Turn unit OFF, unplug it before removing and cleaning the
filter. If you wash the filer, it must be thoroughly dry, before reinstalling it.

3. Obstructed air flow. To function properly, there must be a minimum of 12" clear air space around
the entire unit.
.
4. The cooling coils are dirty and need to be cleaned. Remove the front cover and filter to access
and clean the coils with warm water and dish washing liquid. Rinse , thoroughly dry and coat
coils with a light caating of WD40.

5. The air temperature at floor level is between 40 - 60 degrees F. Most dehumidifiers don't function
function well in that temperature range. Especially in a basement application. The ambient air
temperature at floor level is colder than at chest level. Set the the unit on a sturdy table, counter
top, etc, that can handle the weight of the unit & a full tank of water.

Conduct an in-home test, to check humidity extraction: Place the unit in your bathroom, plug it in and set the humidity extraction level at 32 - 35%. Turn the shower ON hot enough to generate steam. Close any window(s) in the bathroom and Do Not turn the exhaust fan ON. Close the door as you exit the room and wait 15 - 20 minutes before returning. After the time has elapsed, open the bathroom door, turn the shower OFF and allow the unit to run 5 more minutes. Then check the water collection bucket for any signs of water. If you see any, the unit is working as it should and one of more of the above solutions took care of the problem.

If the unit showed no signs of humidity collection (water) in the bucket and you want to have it repaired. The closest Delongi Authorized Service Center(s) to you are in Florida (please see the following link) http://www.delonghiusa.com/index.php?service

I hope this helped you further troubleshoot and solve the problem without having to make a repair. Please let me know. Thanks.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

Several things can cause this problem. The leading one, is that the humidity extraction level is set to high. Lower it to 35%. One of the others, is a dirty or clogged air intake filter. Followed by obstructed air flow. You need to maintain at least a minimum of 12" clear air space around the unit. Also, most humidifiers struggle to operate correctly, if the ambient air temperature at floor level is between 40 to 60 degrees F. This will also cause the fan to run a lot if the unit is set in continuous mode, rather than a timed mode. And finally, if any doors or windows are open, the unit will run forever. Make sure all doors and windows are closed.

Here's an in home test to see if it's working properly. Move the dehumidifier to the bathroom. Plug it in turn it ON and set the humidity/moisture extraction level to 35%. Turn the shower ON hot enough to generate steam. Do Not turn the bathroom exhaust fan ON and close any windows that may be open. As you exit the bathroom, close the door. Wait 15 to 20 minutes before returning to the bathroom. Once you do, turn the shower OFF and allow the unit to run for 5 minutes more. Then check the bucket for any signs of water. If you find some, the unit is working as it should.

If you don't see any signs of water, the unit's compressor may need to be recharged with refrigerant.

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

Is it only the fan motor running that you hear? Or is it the compressor motor and the fan motor in combination?

If it's just the fan motor, it running to circulate the air, in an effort to sense humidity in the air, above the level you have the humidifier set on. Speaking of which, you may have the level set higher than what the humidity is in the house and the unit is just maintaining it. 50 to 60% is high, as opposed to 35%, which is what most folks want to maintain in the hot, humid, summer months.

If you want to test the unit, place in the bathroom, turn a hot shower ON, turn the humidifier ON and set it for 45% or minimum if your unit does not have a LED readout screen. Do Not turn the bathroom exhaust fan ON. As you leave the bathroom, close the door and don't return for 20 minutes. When you do, turn the shower OFF and check the humidifiers water collection bucket. If you see any water, the unit is working as it should. If you don't see any water, it's time to replace that unit. I say that because, at best, the parts and labor to repair the unit would be equal to or almost equal to, the price of a new dehumidifier.

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

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.

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

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. The fan running, may be the automatic defrost cycle, that defrost the coils, if they become frosted over. The defrost cycle, depending on the unit and how is was designed, can last any where from 15 minutes up to 45 minutes.

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 on a regular basis, not is the time to do so. And while your at it, clean the cooling coils too.
