Nothing is working what could be wrong with it

It's basically an air conditioner so if the fan is running---the condenser not plugged up via rats nest---lint----the float switch working---if possible tip over switch working----the system maybe low on refrigerant

the units self testing and it takes a moment to ck that everything is ok , red light ind. it;s found a problem , ck simple things first , empty bucket, ck float sensor inside bucket ck for Level (gravity) ck filter for cleaning and reset filter alarm if present , then move on to more difficult things like is something wrong with cooling fan or did water get inside and dammage something

The fan has to run or the moisture will freeze on the coil, try to help the fan motor turn reach in and the blade a flick in any direction and then pull your long skinny helper out and watch the fan it may just run or give you a idea whats up. They get dirty and I'm sure that it worked last time. Nothing fancy but it might help.

When you powered down the unit, did you just turn if OFF using the controls on the unit Or did you unplug it entirely? If you didn't unplug it, it won't reset itself. Leave it unplugged for at least 30 minutes. As far as the blinking bucket full light is concerned ... It's possible that the bucket is slightly out of kilter and is only making partial contact with the safety switch. Especially if it's sitting on uneven soil or when the bucket get partially full the weight of the bucket is pulling it out of kilter because it's sitting on soil, rather than a hard floor. If nothing else, place it on a 1/2" piece of plywood or OSB and level it.

To be totally candid, I have some concerns about leaving a dehumidifier running, unattended in the crawl space of a house. There's to many things that could go wrong that would have disastrous results.

Hi,

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

How often does the unit run? Does the fan run when the unit is suppose to be running(as the fan pulls the air thru the filter). If every thing operates correctly and the filter is in the right location on the unit then all I can say is that you keep a clean house. Personally I only need to clean the air filter on my dehumidifier about once a summer. I wouldn't be overly concerned if it isn't getting very dirty.

replace 24 volt 1 watt zener diode on circuit board. 1n4749 (nte5081a)
mine was hit by lightning and this fixed it.

Hi,
The fan motors do occasionally get clogged up with fluff - especially if the machine has been operated without the filter screen installed. Also it is possible that some foreign object has fallen into the motor and is jamming it.

With the power off, check to see if the blower will turn when poked with a long plastic pointy thing :-)
