Tip & How-To about Dehumidifiers

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.

Haier dehumidifier will not power on


Turn the ON/OFF Switch to OFF and unplug the unit for 15 minutes.
Once the time has elapsed, plug the unit in and turn the unit ON.

Hopefully, during that 15 minute timeout, the electronics reset and reverted back to the original factory settings. And the unit will turn ON when you press the ON/OFF Switch.

It's also a good idea to check the outlet it's plugged into. It very well could be an issue with the outlet (no power) or the circuit breaker for that outlet has tripped.

If you continue to have a problem getting it started, contact LG Customer Support 1-800-243-0000.

Demudifier worked great, all a sudden it just stopped. No power. Now it won't start up. What should I try?


First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

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

I have two Haier HDN655E dehumidifier's. One works fine and the other wont come on. I have tried unplugging and plugged back in, hit the start button and nothing happens. Is there a reset switch or a fuze that could be blown?


Have you tested the outlet it's plugged into, to make sure it still has power? If it doesn't, check the circuit breaker panel in you home for a tripped circuit breaker. If there is one, unplug the dehumidifier, before resetting it. Then plug the dehumidifier back in. If the circuit breaker trips again, the problem is within the dehumidifier or the outlet is faulty (i.e. Loose wire, burned wire, broken outlet). If the outlet is not faulty, you should contact Haier America Parts and Repair 877-337-3639.

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

fan not working, outlet is live, product is 6 mos old, located in an indoor swimming pool (endless swim machine) Hi E Dry 100,


If the fan does not operate with the fan switch set "on", there is a problem with the power supply, internal wiring, or the fan itself.

First make sure the dehumidifier is plugged in to a working outlet.

Next unplug the dehumidifier and remove the cabinet cover. Check the internal wiring for loose connections.

Next remove the fan and check that it is able to spin freely (by hand). If it spins freely, it should be replaced. Call the manufacturer at 1-800-533-7533 for parts and instructions.

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!
