If it is removing moisture then you need to replace the humidastat
if it is running and not removing moisture then the sealed syestem needs to be looked at

Why compressor comes on for a second then shuts off

Good Morning Friend,

I understand that the compressor on your Frigidaire dehumidifier, model# FAD504TDD, comes on for a second and then shuts off. First, make sure that when you are first turning your dehumidifier on that you put it in continuous mode. After about 3 days of continuous mode, set your appliance to the humidity level you would like. Secondly, the "Compressor" circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Thirdly, make sure the tank is fitted correctly otherwise your dehumidifier will not turn on. Lastly, make sure your dehumidifier has sufficient clearance to operate. There should be a minimum of 12 inches clearance around your dehumidifier. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your dehumidifier status has changed successfully. Hope this is helpful.

-Best Regards-

It continues to shut down after start saying it is full, but it has no water in it. No matter if I take out the bucket and push back in it still says full. Not even a year old!!!

Here's a solution that often works. Turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12-15 minutes before plugging it back in. Then turn the Master ON/OFF Switch to ON and set your control as you normally do. Hopefully, that 12-15 minute timeout allowed the unit to reset itself. If it continues to do this contact Haier Customer Support 877-337-3639 and have your Model Number and Proof of Purchase handy. If it's less than a year old, it's still under warranty.

Good lick. I hope this helps solve your problem.

I have Haier DE45EJ-L I am confused at what the setting should be. The Temperture is 68, when I put the humidity setting at 50 it shuts down, if I put it to 38 moisture is removed from the air. All the...

The unit shuts down when set at 50% because the controller is sensing that the humidity is below 50% RH. It comes on when set at 38 because the RH is higher, so it will try and dehumidify down to 38% RH.
According to the EPA the ideal RH in a conditioned space is 48 to 54%. You can set it and leave it at 50% if you are comfortable there and the dehumidifier will automatically come on when the RH is above 50% and will automatically turn off when the RH is 50% or below.

I have an lg dehumidifier LHD 45EL. The humidity reading reads 15% higher than a stand alone humidistat and the unit will go on for a short time even though the set humidity level is 70%. What gives?

Possibly the primary humidity sensor behind right side grill. Unit MUST be unplugged from outlet. Take right side grill out, unplug sensor from wire socket and plug back. If no help, you need new sensor.

Dehumidifier has shut down

The GFCI outlet needed to be reset. There was no problem with the dehumidifier itself.
