You can test it out by disconnecting the power cord, wait five minutes and plug it back in. If it retains the original settings you are good to go. If you are wondering before purchasing a new unit ask before you buy.

You need to determine what's "running". Here's why: There are three things that must be working to extract water. The 'coil' (a finned metal part that needs air to flow across its surface) may be filled with dust and obstructions, so no air can move...then no water. There is a blower motor that must move the air. If it is seized up and not blowing air...very little or no water. The compressor creates condensation from air moving across the coil (like the moisture than forms on an ice filled glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.

Try cleaning the filter first. Pull it out and then wash it with water and let it dry overnight. Then clean the spigot/nozzle which fills the pan. This often becomes clogged with dust or debris or even insect webs. Once you wipe the nozzle with a rag, really clean it well with a finger. You should feel the rubber gasket at the end of the nozzle with your finger.

Likely the fill nozzle was just clogged so water drips along the top and down the sides of the pan instead of into it.

Good luck.

Why does blower wheel stop on Frigidaire dehumdifier?

Good Afternoon Desi,

I understand that the blower wheel is not spinning on your Frigidaire dehumidifier, model# FAD504DUD. I also see that the compressor will stay on unless the dehumidifier is unplugged. I suggest you contact the manufacturer for further assistance. They can possibly clarify why the compressor stays on and why the blower fan is not working. If not, they should at least be able to point you in the right direction of having your dehumidifier working. Hope this is helpful.

-Best Regards-

I have a whirlpool dehumidifier (AD75UST0) and it appears to be 'dead'. is there a fuse or a reset?

No. I have had a AD75UST0 WHIRLPOOL Dehumidifier for several years. My unit slowly got less and less efficient, then it "stopped" coming on as if it was not working. Upon disassemble and inspection I found fan was no longer spinning. It tries to start then (actually the condenser coils begin to freeze, but no Fan) then it shuts down within 30 sec or so.

I am going to try a replacement Fan and fan start Capacitor (always replace in pairs).

The fan inside is having a hard time rotating...starting to smell. what gives?

If the fan motor is quite hot to the touch when it is running and the smell is like something burning and the fan blade isn't rubbing on the housing then the fan motor bearing are most likely worn out. If that is the case then the fan motor is bad and needs to be replaced.

Dehumidifier won't shut off

Well your dehumidifer runs constantly. My guess seeing how you bought a 30 pint per 24 hrs. Your house better be 400sqft. It is under sized and humidity need to be 30/50 percent to stop mold growth. It cant keep up its two small 50 pint are for 1000sqft 65 pint is 1300sqft. Upgrade now!!!!!

That's pretty normal. Most of these portable units blow quite a bit of heat.

Lifeguard, there are generally no user accessible safety items in dehumidifiers. You are likely describing the start relay which is used to 'boost' the compressor on starting. Jumping it will not help you. It sounds like the compressor is defective. Economically, there is no justification for servicing these units unless they require refrigerant gas or if the fan motor has seized, something you can readily determine. If you don't hear the compressor hum when it should, there is no service procedure available for these sealed units.
