DH40 - Instructions

The knob one turns to set the humidity level was removed. The two screws holding the top on were removed. The top was lifted and swung to the side. After noting which of the two wires went where on the humidistat the wires were removed. Small flat screwdrivers were used to pry back the plastic retainers on one side of the original failed humidistat. The new one was put in place, the two wires were reattached. The knob was replaced. The top was positioned and its two retaining screws replaced. A magnetic phillips screwdriver was handy but not necessary. Piece of cake! Someone with ten thumbs could do it!! Thanks for the prompt courteous attention to the returned erroneous part! Dealing with partselect. Com was a pleasure. . . . . . Thanks!! P. S. The dehumidifier works like new now!!

The forums indicate that one solution for this problem is replacement of the sensor assembly, which is what I did. Upon switching the sensor assembly it DID work for one bucket full, but then went back to indicating bucket full when it isn't. Other fixes indicate changing the switch assembly, which I tried to do but the part has been discontinued. The only other item is replacement of the main computer, which the cost added to the cost of the sensor assembly would equal the cost of replacement of the appliance, so I won't go there.

Troubleshoot on the schematic/wiring diagram to find the defective thermostat. Order a replacement part. Remove all outer covers to gain access to the thermostat. Only tool needed for this is a #2 phillips screwdriver. Cut the leads on the defective part and remove thermostat and replace thermostat, wire cutters/crimper required, splice the thermostat leads, Reassemble the outer covers.

Unscrew and detached front and back panels, and inside framework holding the sheet metal to the body, after removing the sheet metal, unscrew the box enclosing the control board, use needle nose pliers to unhook the sensor module from the board and place the new sensor into the spots where the old sensor was connected (thermostat area, humidity Sensor, bucket switch, and control board). Close up the unit and your good to go.

Googled message to see that it was probably the sensor or the bucket full button. The bucket button is no longer made, but the sensor was available, so I gambled and bought it to try. We removed the outer housing and old sensor. then replaced new sensor putting it in same place and following the path of the old one to plug in wires. the whole housing had to be removed, could not just remove a section. Once replaced, plugged in to test, seemed to work. so replaced all the housing and screws. Unit is working again. Definitely worth the gamble, bc a tech would have been 3-4 times more expensive. My tenant was also confidant about being able to replace the sensor. After we did it, I think I could have done it too.

Taking the case apart and replacing the control unit was a piece of cake. And the part arrived the very day after I ordered it.

Removed all screws from the outside case, then I had access to the motor. Removed 4 screws from the bracket holding the motor assembly in place, removed it from the case. Next I pulled off the broken fan part, installed the new blade and secured it with the supplied bracket. Next I installed the motor assembly in reverse with the 4 screws I removed earlier. I made sure the blade would move freely, no wire in the way. Also, when you remove the motor assembly you will have to remove the motor wires from their attachment points, but is easy, they are just "plugged" in. In any case I recommend you make a small drawing/schematic as to where the wires go for proper hookup later. The last thing is to put the case cover back on, line up the holes and insert the screws you removed earlier. The unit has been running like new now!!

replaced a piece of the plastic at the top of the bucket that seems to be the water gauge. this seems to be fixed. we are very happy

Had to pop open the back. The back did not just unscrew and come off. It has to be pried off carefully. Took the turbo off and put the new one on.

Ordered the new humidity sensor. Removed the sides and top all one piece of the dehumidifier by removing several screws. Removed the cover of the electric circuit box 2 screws. Removed old sensor by unplugging the wires. Installed the new sensor plugged in the 3 wires put the electric box cover back on. placed the sides and top back on screwed them in and it works just fine.

released broken wheels from their position using a screwdriver and secured new ones w/ a pliers.

pried off the plastic fastener with flat blade screw driver set new float in place then pressed plastic fastener back in place

First....you need a metric nut driver...not a standard...this took me five trips to four stores to find. So if you have this model number don't think it is merely a screwdriver and a Phillips. After that the job was simple but the humidistat did not fix my dehumidifier. It was worth the $38 try ...but sadly off to buy a new one...

instructions accompanying this replacement fan were great. Easily understood, correct, and instructive pics.

The switch housing was not exactly the same for easy snap in. I removed the actual switch and installed it into the old housing. Then I found that the male pins were larger than the old ones. I chose to clip off the female connectores, strip the wires, and solder the wires to the pins on the switch. It was easier for me than attempting to change the push on connectors. For me, the actual switch was what I wanted and I fixed it my way. It was easy to do however some folks may want to change the push on connectors. Works great and saved me hundreds of dollars. Thanks.
