Question about Fedders A7DH45B2A Dehumidifier

1 Answer

Dehumidifier continues to run when room/unit are both at 40% hum.

I have the Fedders A7DH45B2A. Is there a "continuous run" on this unit? If so, how do I turn it off/on? I have an attachment to the operations manual that says I do have the "continuous run" capability.. The unit continues to run when both the room and the unit are @ 40% humidity.

Hello,

To turn the unit on, turn the humidity control knob to the off position, before connecting it to the mains. Set the humidity controller to the required humidity level, or fully clock wise to the maximum position for continuous working.

By rotating the knob clock wise the unit will switch off at a lower relative humidity.

To turn the unit off, turn the humidity controller fully anti-clockwise in order for the unit to turn off. The indicator light will go out once this is done.

Good luck.

Why does my dehumidifier run al the time ,i have the humidity set at 45 and when the room temperaturegoes down to 55 it keeps running.


The 45% setting is too low and the setting is never satisfied, so the unit keeps running to try and reach 45%. Try setting to 50 or 55, this is a very comfortable range. I was not clear on the room temperature being at 55 degrees. Is this what your thermostat is set to or is this the actual room temperature. Brrrrrrrrrrrr

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.

I have a Fedders dehumidifier Model A7DH45B2A REV-A. The nipple on the float broke off. Where can I buy a float? Do you have one? How much is it?


Although Fedders, as you knew it is no longer in business, some parts are still available.

Here is a link, with an explodes view of your model's parts.Locate th epart you need and then enter the part number, to see if it's still available. FYI Maytag Dehumidifier parts are interchangeable with Fedders. Fedders made the units for Maytag.

My dehumidfier won't shut off. I check everything out and it's good but it just won't shut off it keep running.


It may be, that you have it running in continuous mode, rather than timed mode. Also, most dehumidifiers fans will run almost continually, to keep the air moving, so the humidity sensor can pickup and increase in humidity, if there is one.

If the above doesn't seem to be the problem with your unit, turn The Master ON/OFF Switch to OFF and unplug the unit for 12-15 minutes. This will give the electronics time to reset themselves, if necessary.

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

My dehumidifier ices up. It will not remove moisture when it ices up. What can I do and is it under warranty?


Hi,

The coils you see on the back of your dehumidifier are the evaporator. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils. To remedy this problem, you can try any of these: Warm up the room the dehumidifier is in. Put the dehumidifier on a sturdy table (the room air is coolest near the ground). Turn the unit off until the room warms up.

Take care.

The coils are freexing up. How can i fix this? fedders dehumidifier a7dh45b2a


Make sure your coils are clean and free of restrictions and that the fan is running. If this is ok, then it is probably a leak in the system resulting in low charge. Cost of new dehumidifier will be cheaper than having it repaired.

Console does not light up after plugging unit in


Check the power cord for rips of loosness where it enters the unit. if the power cored is fine, this will usually be the result of a power supply board failure. you should replace the power board in this case. the original board is unable to process the AC current at this time.
