Noise when unit runs a few seconds after turned noise sounds like the fan is striking something. when attempt to remove the back panel, it will not release so that I can inspect the rear of the unit. All six screws were removed. The manual has been misplaced.

Be careful. i do not know. set at highest setting and let it run. while running, reduce setting to the lowest over a few minutes. at a lower setting you should be able to tell that the compressor has started. run it for 5 minutes, then
unplug your machine. next, feel the cooling coils to see if they are very cold. if they are not cold, your unit needs to be serviced.

So I just had this happen with my Frigidaire fad704dwd dehumidifier. I went to basement and heard it running and sounded off. The compressor was running fan was off which is bad and humidity said 30. I then pushed the off button and it stayed running. I was able to fix it. To make long story short it was a bad ground. I took the plastic back, sides, and front off. There was a green ground (main ground) and Green/yellow ground (fan ground) on the front coil with a bunch of rust. Removed the grounds connected them both together and cleaned the surface area and used a new stainless screw nut and screw to remount the wires to evaporator coil. Everything started working fine after that and I put it back together. Good Luck

The black cylinder is the compressor. It sounds like your unit is cycling the compressor for some reason. If the compressor starts, runs fine, and removes water when you set the humidity control to the driest setting the compressor is probably OK and the problem may be with the humidity control causing the dehumidifier to "short cycle" for some reason. You may need to change the humidity control or relocate the dehumidifier in your crawl space.
If the compressor attempts to start, and then sits quiet for 10 minutes, and then attempts to start again, you have a problem with the dehumidifier. There are a few things that can cause this problem:
Low refrigerant charge
Bad compressor capacitor
Bad compressor overload
Plugged capillary tube or broken expansion valve
are the common causes of this behavior. If you suspect one of these problems, call the factory service department at 1-800-533-7533 for help.

Good luck with your dehumidiifer.

Hello,

With the unit unplugged, open the cover and check the alignment of the fan. If the fan is stuck or rubbing against the fan cowling, adjust the fan motor's mounting hardware so that the fan turns freely.

Good luck.

sounds like the compressor is seized.

When you push the power button, the blower fan comes on. In a few minutes you should hear a second "click"--that is your compressor starting. Do you hear that second click?

The compressor is located in the rear bottom on the right side looking at the machine. After you press the start button and the blower fan comes on, bend over near the back of the unit and listen for the "click".

The fall may have knocked out some wiring -- open the unit (remove back panel, then remove front by taking out screws inside) and see if any of the cables to the front panel or control board came out.

just replace the fan motor is the proper fix. you may dissasemble the fan motor and it may run for a while but the cost of a compressor is not worth the cost of the fan motor

not sure which dehum yo have,but here I go! most fans are not part of the cooling system. first remove the housing where the fan is. turn the unit on and check to see if the fan is turning. if not then just wait till you hear the compressor kick in. if the compressor goes on then you do have a problem w/the fan motor and it will have to be replaced. worst comes to worst just bring it into Sears. they have techs which will let you know what the exact problem is and you can take it from there. make sure you give them the model # first,just to check if the have parts for your dehum.
