Question about Fedders A7DH45B2A Dehumidifier

All the indicator lights work but I can see that the fan is not moving. Does the system operate if the humidity level is low? Or is the fan/motor broken? How can I determine what is wrong?

The fan never stops running. The dehum. works fine that is the only problem. Is it the way I have it set how can I change that?


Bob, some humidifier fans run a lot, because they are designed to keep the air moving and when the humidity level rises, the compressor turns ON to extract the humidity. If you're operating the unit in a continual mode, it's not unusual for the fan to run almost constantly.Especially, is the humidity extraction level is set at or above 50%. Lowering it to 35% will cause it to extract more humidity and will turn on an off less.

Hope this helped you and thanks for choosing FixYa.

Why does the fan run non stop? the compressor runs and shuts off but the fan just runs on high and low. I have 3 other dehumidifiers that the fan runs only when the compressor runs...why doesnt the...


Depending on the time sequence you have this unit set to run, Fredrich's are designed so that the fan runs almost constantly, to keep the air moving. When it senses a rise in humidity above the level you have it set on, the compressor turns ON and runs until the level of humidity is lowered. This is especially true, if you are operating this unit in continual mode.

Hope this helps you and thanks for choosing FixYa.

Unit no longer removes water/humidity from air. The filter had been extremly clogged up (now clean) but is fan suppossed to move when it's running ? If so - is it electric or belt driven ? Is...


Well, we know the filter was playing a role in it.. Good job on cleaning that. Depending on where you have the humidity extraction level set, the fan could run all the time (It's direct drive. No belt). I suspect if you lower the humidity extraction level to 35%, you will see/hear water collecting in the bucket after about 30 minutes to an hour of operation.

Also, maintain at least 18" of clear air space around the entire unit.

In addition, if you're using this in a basement 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.

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

My Kenmore dehumidifier has stopped drawing water from the air to the collection receptical. Fan still runs at high and low speeds.


A couple of things may be happening: The humidity extraction level may be set to high and it can't extract any humidity at that level. Reset/Lower it to 35%. The fans on most dehumidifiers run almost constantly (designed that way) so that it keeps moving the air around. If the sensor picks up a higher humidity level than what it's set to maintain, the compressor will turn ON. This is particularly true, if you operate the unit in continual mode, rather than a timed mode. Also, a dirty or clogged air intake filter, hinders the units ability to remove humidity/moisture.

In addition, operating the unit is ambient air temperature of between 40 & 60 degrees F, causes the unit to struggle to dehumidify the air and the fan to run continuously. Obstructing the air flow around the unit, will also cause it to not function as it should. Maintain a minimum of 12" of free air space around all 4 sides of the unit.

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

Is this a low temp model, as it is not dehimidifiying but fan is running


The model you have was made by Fedders for Maytag. The fan runs as a recirculating fan, to continually sense when the humidity level rises, above what have the unit set on. Here in, may be the problem. If you have the humidity level set higher than 50%, that's pretty high and the unit want remove much if anything. It will just continue to maintain that level. Keep in mind, the unit's humidity level must be set LOW, for the compressor to kick on and start removing humidity. By low, I mean 35% or minimum, if your unit does not have an LCD display.

I must caution you, that there is associate on this website that would tell you, that the level should be set on Maximum. Believe me, that simply is not the case. That is, unless you want your home to be hot and humid.

Hope this helps you to troubleshoot and solve the problem.

My humidifier dont collect water



Hi,


There are many reasons why a dehumidifier will not work or collect water.


Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier

Dehumidifier is running but no water is in bucket

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.

Santa fe dehumidifier running but not producing any condensate. No ice forming on the coils and filter is clean.


You should check if the compressor is running. Your description makes it appear that the fan may be running and the compressor may not be running.

There are many things that can cause a compressor to cease running:

Open defrost thermostat
Bad run capacitor
Low refrigerant charge (caused by refrigerant leak)
Bad compressor relay
Bad compressor overload
Bad compressor motor

Other things to check:

If the fan switch is set to "on" and the humidity control is set to a high humidity level, the unit may appear to be running, but the compressor will not operate. Check the setting of your humidity control.

If the dehumidifier is operating in a room with a high temperature and a low dew point (very low relative humidity), it may be unable to remove any more moisture from the air.

If you are not comfortable troubleshooting the unit on your own, call the manufacturer service department at 1-800-533-7533, EXT 8459. They are very helpful.

My dehumidifier only the fan runs


Are you sure you have the humidity level set low enough for the compressor to turn on? If not, the fan may run anyway.
Your unit may be designed to run the fan continuously despite the fact that the room has reached the set humidity level. This design feature is intended to keep the air moving which helps mildew problems in both the room and on the surfaces of the dehumidifier itself. Check your manual.

Humidifier stopeed working


You have a bad fan motor. Put your hand against the grill to see if there any air movement. You need to buy a new fan motor assembly, it is attached by two long
bolts, easy to swap, except the wiring may not be easy. May have to cut the 3 wires and resolder. Get to the motor by removing the back panel and then the fan. Removing the fan may not be easy, they put some gunk on the spidle thread.

The cheapest price I have seen for the motor is $27-$28, shipping about $8 and tax
about $1.5.
