Question about Haier HDN305 Dehumidifier
The unit was running fine for 2 1/2 years. Just stopped running. No lights, turn Humidistat nothing. Took unit apart checked fuse. Metal strip in fuse is intact. Float switch checked ok for continuity. Did not detect continuity on the Humidity switch. Is it possible it is just the humidity switch or could it be the capacitors in the unit? A new Humidity switch is around $26, if I have to replace other parts, I might as well buy new. Any pointers?
use a jumper cord and go directly to the compressor to see if it will run. if it don't run, open up the motor box and see if there is a klixon overload inside. this should be normally closed. if it isn't replace it. the klixon is a thermal overload cutout. it usually trips because of high winding temperatures and protects the motor inside. the compressor is a hermetically sealed unit. no, or little freon will cause the motor to overheat.

Hi, I just cleaned my dehumidifier and had the same problem as you. I used a spray water bottle and was not aware that the humidity sensor was being soaked. Very stupid of me!! Luckily I have two same dehumidifiers and used the other sensor to replace the one that I so stupidly ruined, and behold my machine worked again. Now I have to buy another sensor. To make sure we are talking about the same thing, my sensor is white,about 1 inch by 1/2 of an inch. It as 4 wires connected to it. To access it you remove the water tank, you will see 2 screws. Remove those, and pry the front panel loose. Be careful the top of the panel is held by two plastic hooks, they break easy. The sensor is located on the right side just above the radiator, under a produting oval lip which as foam around its rim. The wire colors are red black blue and yellow. Good luck Herman

Thanks qrx1llb3 for the help!
After carefully removing the plastic covers (yes, u need to remove both, I removed first the back one then the front one by pulling up, then disconnect the cable that joins the panel on the front cover with the electronic board on the upper right area) I found the electronic board with the blown up fuse. My was under a blue plastic cover. I'll try to replace it and see what happens! thanks for the help! :)

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.

After all that testing you have diagnosed the problem. It is the main circuit board. So there is not reason to do any more test. I would just get a new control board and off you go
