You can test the humidistat fairly easily, using a volt-ohm meter. Just set the meter to RX1 scale and attach its leads to the humidistat's terminals. Rotate the humidistat's knob as far as it will turn in both directions. If the volt-ohm meter registers zero ohms through only part of the humidistat dial's range, the humidistat is working. If it registers zero through the entire range, it's broken and must be replaced. Dehumidifier Overflow Cutoff Switch Test- Using a volt-ohm meter, you can tell if the overflow switch works or not. Clip the leads to the terminals on the switch. Depress the bar or trip lever on the switch. If the meter's needle doesn't show continuity and no continuity as the switch is clicked back and forth, the switch is probably faulty and will need replacement.

How to fix\repair a Dehumidifier if it doesn't Work
If your dehumidifier shows no signs of life:
1) Check the power. Be sure it is plugged into a working outlet and turned on.
2) Unplug the dehumidifier unit and check the power cord. If necessary, replace the cord.
3) Remove the cover panel.
4) Look for ice. If you see any ice blocking parts, let the ice melt and do not use the unit until the room temperature exceeds 65 degrees Fahrenheit (most dehumidifiers are not designed for use in colder spaces and may freeze up). Many people find that, by unplugging the unit and waiting about 30 days into the season, the problem is solved.
5) Remove and test the overflow cutoff switch.
6) Remove the humidistat and check it. Replace it if necessary.
7) If the unit still doesn't work, call a repairperson-the compressor motor or the relay and overload switch may be the problem.

Will turn on but no dehumidifying so there is no water in the bucket.
well 67%rh is considered low (70%rh is normal) units will produce much less water when tasked to operate in low moisture air , this is why all the new units have air temp ratings of 60Deg or less. but still the unit should try to go thru all the motions ,that you can easy verify , just by u watching /listening closely
set unit to work normally , listen 4 the fans inside to come on and a few moments later the compressor will come on if everything is working well , try adjusting the humidistat up to a value of say 80% listen 4 one fan and compressor to stop , this is all normal reset desired setting on humidistat
if unit fails any one of these simple tests it has an internal fault inside it and requires service

Our Challenge 4151319 Dehumidifier has ceased to collect water. The fan operates perfectly. Can I get it serviced in Devon?
Hi,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again.

Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue.

This situation will have to be addressed by a qualified technician.

Good luck

Humidty reading remains at 84%
Dehumidifiers are generally a very simple appliance, however a humidistat is one of those items a person tends to rely on to provide feedback. You may want to remove the grille area where the humidistat is mounted and inspect for foreign material in the way of the sensor. If nothing foreign is detected then you should replace the humidistat.

If my assistance helped resolve this issue, please show your appreciation by rating how effective my advice was in resolving this issue.
Thank you,

Humidistat
the humidistat is inside the machine behind the control panel. it has a mylar piece that expands and contracts according to room humidity. one side is connected to a super sensitive switch that is part of the fan/compressor circuit. you could just jump this out with a piece of wire but you'll have no control over the humidity. the unit will just keep on running.

Haier Dehumidifier HD50-T
A humidistat from a different brand will work, provided it is mounted well & hooked up properly. Make sure the replacement is designed to switch the compressor directly.

My dehumidifier is dead
WIZ huh? NAGEV says:

check the plug!??? - DUH! I also love ...

5) Remove and test the overflow cutoff switch.

6) Remove the humidistat and check it. Replace it if necessary.

7) If the unit still doesn't work, call an appliance repair person!!!

I guess he's only helping the repair person! Who would pay for this kind of advise? The layperson needs details not big words!

Powers on but unit doesn't run see more details... Subject: Question regarding my Dehumidifier I have a Dehumidifier model # A7DH45B2A Rev-A-R Fedders Serial # GT947825194W Date Purchased 10-6-2005 It stopped working and we have cleaned the filter and it would not run. The humidity selection works and the temperature selection works but unit will not start and run. I understand that it is out of warranty but thought there might be something I can do to give it a few more years. It is well maintained and looks like new so it has not been abused. Would appreciate any hints to see if we can bring it back to functioning. Thanking you in advance for your help.
