Haier HDN305 Dehumidifier

The unit stopped working.  No lights, nothing.  Did all recommend troubleshooting related to the tank and switch that cuts the machine off when the tank is full.  Also removed back panel and pulled the wires off the switch and touched them together.  Nothing.  Any thoughts?

    Our haier HDN305 was used 2 summers. It acts like it is completely dead. We tried to clean the inside board, but still nothing. Disappointed that the manual says to call your service man...like that is so cheap. My other one has been running for 10 years...do they make them so cheap today that they only last that long? Please help if you can...my husband is very handy!

The Comfort-Aire crapped out again! We started the season with a little 17-pint Sears, but it wasn't cutting the mustard getting the accumulated moisture out of the cellar, so we fired up the Comfort-Aire 65-pint machine. It got the humidity down to 50% pronto, and kept it there for the better part of a week when all of a sudden it quit. Died! Nothing! Not a glimmer in the control panel, and pushing the buttons did absolutely nothing. Unplugging it and plugging it in again produced a faint "chirp" but that was all. Naturally, the thing is weeks out of warranty. Without the warranty, the nearest service place wants a $60 "consultation fee" just to look at it, so I decided to see if I could fix it myself before seeking professional aid.

After getting an exploaded view of the machine from the web, I removed the collection bucket, the filter, and the two screws from under the plastic front cover. In addition to the two screws, the cover is held by little tabs that fit into notches in the steel sides. To get the plastic cover off, I slid a wooden popsicle stick under the plastic, thus stretching the plastic enough to get the tabs out of their holes without scratchng the unit.
The front cover is tethered to the unit by a cable attached to a circuit board which forms the back of the push-button control panel. On one side of this circuit board there is a row of 14 soldered connections. They are very close together, and any conductive contaminent that gathers between them is guaranteed to short them out. That's apparently what happened to mine, for scraping between them with a toothpick, and cleaning them with a toothbrush
brought the unit back to life again. That's all it took to repair my Comfort-Aire. The plastic cover snaps back
in place easily.

Hauier dehumidifier HDN305 suddenly won't turn on. No motor goes on and no red or green lights go on either. It's properly plugged in to a functioning electrical outlet which has a functioning...


You have already checked everything I would have suggested, so the only other thing I can think of is the temperature in the room, may be affecting it. If the ambient room temperature is above 112 degrees or below 32 degrees, the unit will shut OFF and not restart, until the temperature is within that range.
If you continue to have problems starting the unit, contact Haier America Customer Support 877-377-3639.

Hope this provided some help to you.

Haier hdn305 dehumidifier does not turn on


Had the same problem with two HDN455's and took them to a local electronics repair shop. They replaced a Zener ZD2 diode for a total cost of $53 and now is working fine.

Dehumidifier won't run


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

Hi,
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! :)
