Haier HDN655E Dehumidifier - Answered Questions & Fixed issues

The fuse is not really needed. Look at the sticker on the compressor in the back and you will see it is rated at 30 LRA which is locked rotor amps. Obviously if the compressor fails to start instantly for any reason that 30 amps is going to blow that 12 amp fuse (which is a fast acting instead of a slo-blo for whatever dumb reason).

The fix is simple, move the black wire that comes from the power cord from the terminal marked L in the lower right corner of the board to the unused terminal marked common on the big relay in the lower left of the board directly above the fuse. This will bypass the fuse and allow the thermal cutout on the compressor itself to do its job when the compressor fails to start due to short cycling.

I just had one of these units given to me because it was DOA and when I found the fuse blown I figured the compressor was shorted but after performing this fix the unit works perfectly and is drawing a normal amount of power according to my Kill-A-Watt meter.

incomplete question - try again please?

Actually, your husband is correct. The settings reflect the amount of humidity you want to remain in the house. I really don't think you want to leave 50 to 60% humidity in the house.

35% removes the greatest amount of humidity.

take the thing back,its under warranty if only a week old

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

It is not abnormal for ON to show up when you first push the arrow up or arrow down button. If you want to lower the humidity press the arrow down button again, once the ON lights up. The lower you take the percentage the more humidity will be removed.

Patty, the model you have has been retired. However, Haier Customer Support 1-877-337-3639 can help you. They can email you the manual as an attachment.

I hope this helped you and thanks for choosing FixYa. Have a great day!

To troubleshoot the problem: First start with the wall outlet. Is there still power to it? If not a circuit breaker in your homes breaker panel may have tripped. Is there a lose wire connection in the outlet or is the outlet damaged inside? If all of these things check out OK, try plugging the unit into another outlet that's on a different circuit.

Other causes:

The bucket is full. Unit shouts off completely when this occurs.

The bucket is not installed properly. Remve bucket and reinstall it "squarely" from top to bottom
into the bucket holder.

If the ambient room temperature is 112 degrees F or lower than 32 degrees F, the unit will shout down to protect the compressor. Wait 3 minutes and then restart the unit.

If all of the above troubleshooting fails to resolve the problem. Call Haier Customer Service

A dehumidfier works by heat, so it puts out a lot of heat that is exhausted back into the room. An air conditioner works with heat also and it also takes the humidity out of the air, BUT it exhaust to the outside.

Debi, there are 5 basic, but solvable reason for what you described. Please pay particular attention to number 1 & 5.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications . Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helped you to further troubleshoot & solve the problem.

If you're referring to the fuse in the plugin socket and Radio Shack couldn't help you. Your best bet is to contact Haier Customer Service (877) 337-3639. As it may be a European type fuse.

Hope this helped you. Please let me know. Thanks.

Bob, you don't need to plug the hole for the water to drain out the hose. Once you remove the hose connection cap and connect a hose, no longer than 5 feet (a garden hose will work), the water will drain from the hose and not into the bucket. That is, unless the drain tube is clogged. In which case, an 18" long, plastic, Zip Tie, appropriately sized to fit in the hole, works well to unclog it.

Hope this helped you. Please let me know. Thanks.

I suspect from what you have described, that the humidity extraction level is set to high. Lower it (Arrow Down) to 30-32%. If the filter is clean and the water collection bucket is installed properly, the unit should start working, shortly there after.

To assist you further, I have included a link to the Owner's Manual for your unit. Just in case you have misplaced yours. You can download and print the manual for future reference.

Hi! Either the hose is clogged or the hose connection on the unit or the interior tubing to the hose connection is clogged. OR the hose is over 5 feet long. OR the hose is not sloped downward from the unit. The unit depends on gravity to drain thru a hose.

To clear a clog in the hose connection and/or the interior tubing:

Use an 18" long plastic Zip Tie or something similar that is appropriately sized to fit the inside of hose connect and tubing (NO wire coat hangers though). Carefully insert the Zip Tie into the hole and continue to push it in, until you reach a bend in the tubing. You must, gingerly work it past the bend, until the Zip Tie bottoms out or you run out of usable Zip Tie. Slowly pull it back out while rotating (twisting it). This will help dislodge any clogs. When you start to reach the inserted end of the Zip Tie, be prepared for some water to follow.

Hope this helped you to solve the problem. Please let me know. Thanks.
